King Size Mattress Online - Premium Comfort & Support

A king size mattress is the largest standard sleeping size sold in India, measuring 72 inches wide by 78 inches long. Split between two adults, that works out to roughly 36 inches of personal width each, which is about as much room as a single bed gives one person. The extra span is the entire reason the size exists. It is what stops one person turning over from waking the other one up.

The mattress matters more than the frame it sits on. A frame carries weight; the mattress decides how your spine is held for seven or eight hours every night. Wakefit's king size mattress range covers memory foam, latex, pocket spring, dual comfort and adaptive cooling grid builds in this one size, which makes the real decision a question of feel rather than dimensions. If you are still settling the bed itself, our king size bed guides walk through frame styles, storage bases and room planning.

Shopping this size online also removes the two-minute showroom test, which was never a real test. Nobody can judge a mattress by lying on it in a shop with their shoes on and a salesperson watching. That is why every Wakefit mattress ships with a 100-day trial: you sleep on it at home, through hot nights and cold ones, and decide once your body has actually adjusted. Buy king size mattress online direct from Wakefit and the price you see is the direct-to-customer price, with free delivery included and no showroom margin sitting on top of it.

Why Choose a King Size Mattress?

A king size mattress earns its floor space the moment more than one body uses the bed. Below that, it is a comfort upgrade rather than a necessity, and a queen will usually do. The size makes the clearest difference for:

• Two adults who share a bed every night and would rather stop negotiating over the middle of it

• Parents whose children migrate into the bed at 3 am and stay there

• Anyone taller than roughly 5 feet 10 inches, for whom a shorter mattress means feet hanging over the edge

• Restless sleepers who change position several times a night and take space with them

• Couples with a pet that has decided the bed belongs to it

Spacious Comfort for Couples and Families

A king size bed mattress gives each adult about 36 inches of width. That sounds like a technicality until you compare it with a queen, where the same two people get roughly 30 inches each and every turn is a negotiation. The width is also what makes a king work as a family bed on weekends, when a child or two ends up in the middle and nobody has to sleep sideways. If you are choosing a mattress for king size bed frames with a storage base, the extra length matters too, because 78 inches leaves headroom for a tall adult instead of putting their ankles past the end.

Enhanced Comfort for Restful Sleep

A comfortable king size mattress does two jobs at once: it keeps your spine in a straight line and it takes pressure off the shoulders and hips, which are the two points carrying most of your weight when you sleep on your side. Space helps with both. When you are not bracing against the edge of the bed or against another person, your muscles stay relaxed, and relaxed muscles are what let you fall back asleep in thirty seconds instead of twenty minutes after a midnight turn.

Wide Range of King Size Mattress Options

The types of king size mattresses on sale in India have multiplied in the last few years, and that is genuinely good news, because firmness preference is personal in a way that shoe size is not. A side sleeper with shoulder pain and a back sleeper with a stiff lower back want opposite things from the same bed. Memory foam, latex, pocket spring, dual comfort and grid constructions each answer that differently, and the sections below explain which does what before you commit.

Explore Different Types of King Size Mattresses at Wakefit

The king size mattress types below are all built to the same 72 x 78 inch footprint, so the choice is entirely about what happens in the layers above the base. Read them by how you sleep rather than by what sounds premium. The full Wakefit mattress range carries the same constructions in smaller sizes if you are buying for a second bedroom at the same time.

King Size Memory Foam Mattress

A king size memory foam mattress works by softening under body heat and pressure, so it moulds around the shoulder and hip and then fills the gap at the lower back. That contouring is why a memory foam mattress king size buyers choose for back support tends to suit side sleepers and anyone who wakes with a sore shoulder. Wakefit's ShapeSense range sits here, with an orthopedic foam layer designed to hold the spine level rather than let the hips sink.

King Size Latex Mattress

A king size latex mattress feels different from foam in a way most people notice within a minute. Latex pushes back. It gives you contour without the slow-sinking sensation, it returns to shape instantly when you move, and it sleeps cooler because the material is naturally more open. It is the pick for people who found memory foam too warm or too enveloping, and for anyone who changes position often and does not want to climb out of a dent each time.

King Size Grid Mattress

A king size grid mattress uses a moulded polymer grid instead of a solid foam top. The grid walls buckle under concentrated pressure at the shoulder and hip and stay standing everywhere else, so you get pressure relief and support from the same layer. The open structure also lets air move straight through, which is why grid constructions run noticeably cooler through an Indian summer. Wakefit's XpertGrid is built on this principle.

King Size Dual Comfort Mattress

A King Size Dual Comfort Mattress is a flippable mattress with a firm side and a soft side, and it is the most practical answer to a problem couples run into constantly: two people, two firmness preferences, one bed. It also handles the seasonal shift, since a firmer surface feels better in summer and a softer one in winter. If you are genuinely unsure which firmness suits you, this construction lets you test both without swapping the mattress.

King Size Pocket Spring Mattress

A king size pocket spring mattress holds each spring in its own fabric pocket, so springs compress independently instead of transmitting movement across the bed. That independence is what makes a king size spring mattress the strongest option for motion isolation, and why a spring mattress king size couples buy tends to work well when one partner keeps hotel hours. The coil layer also gives more bounce and more airflow than solid foam, with a comfort layer on top for contour.

King Size Plus Mattress

A king size plus mattress is the thicker, more layered version of the standard build, usually adding an extra comfort layer, a plusher top and a longer warranty. The Wakefit ShapeSense Orthopedic Infiniti sits in this tier and carries a 12 year warranty. Plus constructions suit heavier body weights, people who want a more cushioned surface without losing spine support, and anyone who wants the mattress to be the nicest thing in the bedroom.

King Size Mattress Size Guide: Find the Right Fit for Your Bedroom

The standard king size mattress size in India is 72 inches wide by 78 inches long. Get that number right and everything downstream falls into place: the frame, the bedsheet, the mattress protector and the walking space around the bed. Get it wrong and you are returning a bedsheet set every time you order one.

Standard King Size Mattress

A standard king size mattress in India measures 72 x 78 inches, which is 6 feet wide by 6.5 feet long. Indian sizing runs Single, Diwan, Queen and King, with the king at the top of that ladder. A single is built for one adult, a diwan covers the 48 inch double width, a queen at 60 inches wide suits two adults in a normal bedroom, and the king adds a further 12 inches of width on top of the queen. That 12 inches is the whole upgrade, and it is worth understanding it clearly before you buy, which is why the queen size mattress comparison is worth a look if your room is under about 11 feet across.

King Size Mattress Dimensions

The king size mattress dimensions are 72 inches by 78 inches, and the king size bed mattress size you order should match the internal measurement of your frame, not its external one. Frames add their own thickness on every side, so a frame that looks 75 inches wide from outside is usually 72 inches inside.

The same size gets typed into search in almost every possible format, which causes a surprising amount of confusion. All of these describe exactly the same product:

• 72x78 mattress and 78x72 mattress - identical, just width-first or length-first

• 72×78 mattress and 78×72 mattress - the multiplication sign version that phone keyboards produce

• 72*78 mattress and 78*72 mattress - the asterisk version typed on a laptop

• 78 72 mattress - the separator dropped entirely

• mattress 72*78, mattress 78*72 and mattress king size 78x72 - marketplace listing titles that lead with the word instead of the number

In feet, a 78 x 72 mattress in feet king size works out to 6.5 feet long by 6 feet wide. The word order moves around just as much as the numbers do, so bed mattress king size, mattress bed king size, mattress king size bed, king bed mattress and king size mattress for bed are all the same 72 x 78 inch product under different listing titles. If a seller quotes anything other than 72 and 78, they are quoting a different standard, usually the American one, and your Indian-sized bedsheets will not fit it.

Mattress Thickness

King mattress thickness changes how a mattress feels far more than most buyers expect, and it is the specification people skip. In India, king size mattresses are commonly sold anywhere between roughly 6 and 12 inches deep. Thicker is not automatically better; it is better for specific bodies and specific frames.

• A 6 inch mattress king size buyers pick is the lean option - lighter, easier to move, suited to lighter body weights and to storage beds where a deep mattress makes the lid hard to lift

• 8 to 10 inches is the everyday range, with enough depth for a proper comfort layer over a supportive core, and it suits most adults

• A 12 inch mattress king size shopper chooses is the plush end - more layers, more cushioning, better for heavier body weights and for anyone who wants a hotel-bed feel

Check the thickness against your frame before ordering. A deep mattress on a tall bed frame can put the sleeping surface high enough to be awkward to get into, especially for older family members.

Ideal Room Size

A king size mattress on a frame takes up roughly 6.5 feet by 7 feet of floor once you allow for the frame itself. Leave about two feet of walking space on both sides and at the foot, and the bed alone needs close to 10.5 by 9 feet. In practice, a king sits comfortably in a bedroom of about 12 by 12 feet or larger. Below roughly 11 feet of wall width the bed starts to dominate, side tables stop fitting, and a wardrobe door may not open fully. Measure the room before you fall in love with the size.

Firmness Levels

Firmness is not a quality rating, it is a fit. Side sleepers usually want medium to medium-soft, because the shoulder and hip need somewhere to go. Back sleepers do best on medium-firm, which holds the lower back without letting the hips drop. Stomach sleepers need firm, since anything soft lets the midsection sink and puts the lower back into an arch all night. Heavier body weights generally need a firmer surface than lighter ones to get the same level of support, which is why two people can describe the identical mattress in opposite terms.

Key Features to Look for in a King Size Mattress

The king size mattress features that matter are the ones you feel at 4 am, not the ones printed on the packaging. Six are worth checking before you buy.

• Spine support - does the construction hold your back in line, or does it let the hips sink?

• Pressure relief - how does it treat the shoulder and hip on your side?

• Motion isolation - can your partner get up without waking you?

• Breathability - does it trap heat through an Indian summer?

• Material quality - foam density and latex or spring grade, not just layer names

• Warranty length - the clearest signal of what the brand expects the mattress to survive

Spine Support

Support is the non-negotiable one. A mattress should hold your spine in the same gentle S-curve it has when you are standing. Too soft and the hips drop into a hammock; too firm and the lower back is left unsupported with a gap under it. The best king size mattress for any individual is simply the one that keeps that line straight for the way they actually sleep.

Pressure Relief

A good pressure relief mattress spreads your body weight instead of concentrating it at the shoulder and hip. Those two points carry the load when you sleep on your side, and concentrated pressure there is what causes the numb-arm wake-up and the constant turning. Memory foam and grid layers are the strongest performers here, because both deform locally exactly where the pressure is highest.

Motion Isolation

A motion isolation mattress absorbs movement at the point it happens rather than sending a ripple across the bed. This is the single most underrated feature in a shared bed. Pocket springs and memory foam both do it well, since each spring or foam cell responds independently. If one of you works late or gets up before sunrise, this feature is worth more than any other on the list.

Breathable Fabric

A breathable mattress moves warm air out instead of storing it under you. In most of India this is a nine-month-a-year problem, not a luxury. Knitted covers, open-cell foam, latex and polymer grid structures all move air better than dense closed foam, and the difference shows up as fewer 3 am wake-ups in April and May.

Premium Materials

A premium mattress is defined by what is inside it, not by the badge on the cover. High-density foam holds its shape years longer than low-density foam at the same thickness. Genuine latex outlasts foam blends. Individually pocketed springs behave completely differently from a connected coil unit. Read the layer specification, not the marketing name given to the layer.

Long-Lasting Durability

Durability is the feature you only judge in year five, which is why warranty length is the most honest shortcut available to a buyer. A brand that covers a mattress for 10 or 12 years is telling you what it expects the foam to survive. Wakefit's ShapeSense Orthopedic Classic carries a 10 year warranty and the ShapeSense Orthopedic Infiniti carries 12 years, both stated on the product itself.

Why Choose a King Size Mattress for Couples with Different Sleep Preferences?

Most couples do not have the same body weight, the same sleeping position or the same idea of firm. A king size mattress is the only standard size with enough width to let two different sleeping styles coexist without one person compromising every night.

Spacious King Size Mattress for Couples

Width solves more arguments than any feature. With 36 inches each, one person can sleep starfished on their front while the other curls on their side, and neither is touching the other. On a narrower bed the same two people are permanently aware of each other, which is exactly the low-grade disturbance that stops sleep going deep.

Motion Isolation for Undisturbed Sleep

If one of you is up at 5.30 am and the other at 8, motion isolation is the feature that keeps the second person asleep. Pocket spring and memory foam builds contain movement locally instead of transmitting it across the surface. Combine that with king width and a partner getting out of bed becomes something you sleep straight through.

Dual-Comfort King Size Mattress

When one of you wants firm and the other wants soft, a flippable dual comfort build gives you both surfaces in one mattress. You test each side for a few weeks and keep whichever wins. It is the cleanest way to settle a firmness disagreement without ordering two mattresses or splitting the bed into two units.

Hybrid and Latex King Size Mattresses

Hybrid and latex constructions are the middle ground that suits mismatched sleepers. Latex supports heavier weights without collapsing and stays responsive for lighter ones. A hybrid pairs a spring core with a foam or latex comfort layer, so it works as a spine support mattress for the back sleeper and as a pressure relief mattress for the side sleeper at the same time. Either way, what you are buying is a spinal alignment mattress that holds two different bodies level rather than favouring one.

How to Choose the Right King Size Mattress for Your Needs

Six checks, run in this order, will shrink the shortlist fast. Most people start with budget and work backwards, which is exactly why they end up on the wrong king size mattress.

• Firmness - decided by sleeping position and body weight, not by preference in a showroom

• Material - foam, latex, spring, grid or dual comfort, based on how warm you sleep

• Thickness - matched to your body weight and your bed frame height

• Sleeping position - side, back or stomach, for both people sharing the bed

• Budget - the total cost over ten years, not the number on day one

• Warranty and trial - what happens if you get the decision wrong

Firmness Level

Start here, because firmness is the one variable you cannot correct with a topper later without wasting the mattress underneath. Side sleepers lean medium to medium-soft, back sleepers medium-firm, stomach sleepers firm. If the two of you disagree, a dual comfort build or a latex construction handles the gap better than picking a compromise firmness neither of you wanted.

Mattress Material

Material decides temperature and feel. Memory foam hugs and holds warmth. Latex is responsive and cooler. Pocket springs give bounce and airflow. Grid runs coolest of all. If you live somewhere hot and sleep warm, weight this factor heavily, because no amount of support makes up for waking at 3 am overheated. For a longer read on sizing and construction, our guide to king size mattresses and king sizes goes deeper.

Mattress Thickness

Match thickness to body weight and frame. Lighter sleepers are well served by 6 to 8 inches. Average to heavier body weights usually want 8 to 12 inches so the comfort layer is not compressed flat against the core. Then check the total height against your bed frame, because a deep mattress on a tall frame makes the bed a climb.

Sleeping Position

Work out both sleeping positions honestly before shortlisting. People rarely sleep in the position they think they do; watch which side you wake up on for a week. Side sleepers need pressure relief at the shoulder and hip. Back sleepers need lumbar contact. Stomach sleepers need a flat, firm surface that stops the hips dropping.

Budget

King size mattress price is driven by four things and nothing else: the material, the thickness, the number of comfort layers and the warranty length. A thicker mattress with denser foam and a longer warranty costs more than a slim single-layer build, and that gap is the same whether you are comparing mattress king size price listings, king size bed mattress price listings or king bed mattress price listings across sites. The honest way to compare is cost per year of use rather than the number on day one - a mattress that holds its shape for a decade is cheaper in the end than one replaced twice. Buying direct also removes the retail margin that normally sits on a mattress, and no-cost EMI spreads whatever remains.

Warranty & Trial

Warranty tells you what the brand expects the mattress to survive, and the trial tells you what happens if you get it wrong. Every Wakefit mattress comes with a 100-day trial, which is long enough for your body to adapt and for you to sleep through a change of season. That risk reversal matters more on a king than on any other size, because it is the biggest, heaviest and most expensive mattress in the house. Buy king size bed online with a trial attached and the decision stops being a gamble.

Explore Wakefit's Best-Selling King Size Mattresses and Prices

If you would rather start with what other homes are already sleeping on, these five move fastest from the king size range. King size mattress price varies with material, thickness, layer count and warranty length, so the live figure sits alongside each model below rather than being quoted in this text. Treat this as a starting shortlist rather than a ranking, because the best king size mattress is decided by your sleeping position, not by sales volume.

• Wakefit ShapeSense Orthopedic Classic Memory Foam Mattress | 10 Years Warranty

• Wakefit ShapeSense Orthopedic Infiniti Memory Foam Mattress | 12 Years Warranty

• Wakefit Elevate Pocket Spring Mattress with Memory Foam

• Wakefit ErgoTech EcoLatex Classic Mattress

• Wakefit XpertGrid Classic Mattress | Adaptive Cooling Grid | 10 Years Warranty

Read that list by construction rather than by name. The ShapeSense Orthopedic Classic is the orthopedic memory foam starting point and carries a 10 year warranty. The ShapeSense Orthopedic Infiniti is the plusher, more layered version of the same idea with a 12 year warranty behind it. Elevate is the pocket spring option, which is where to look if motion isolation and bounce matter most. ErgoTech EcoLatex is the latex build for anyone who found memory foam too warm or too enveloping. XpertGrid is the adaptive cooling grid, and it is the coolest-running of the five through an Indian summer.

Anyone searching for the best king size mattress in India is really asking a question with five different right answers, because the winner depends entirely on how you sleep. Side sleeper with shoulder pain, start with memory foam. Back sleeper with a stiff lower back, start with the orthopedic builds. Sleep hot, start with grid or latex. Share the bed with a shift worker, start with pocket spring. The 100-day trial exists precisely so that this shortlist does not have to be right on the first attempt.

What Makes Wakefit King Size Mattress the Perfect Choice for Your Home?

A Wakefit king size mattress is built the way the rest of the range is: designed around how Indian homes actually sleep, comfort-tested before it ships, made in ISO-certified facilities, and sold direct so you are not paying for a showroom floor. More than 55 lakh customers have bought a Wakefit mattress, and the range holds an average customer rating of 4.5 out of 5.

Selling direct changes more than the price. It means the mattress is designed for Indian bed frames and Indian bedsheet sizes rather than adapted from an imported specification, and it means the 100-day trial is a real policy rather than a line in the terms. The name gets typed a few ways in search - some people look for wait fit mattress - and either spelling lands on the same brand and the same trial.

If you have been searching for a mattress shop near me, it is worth knowing what that search actually buys you: two minutes lying on a mattress, fully dressed, in a lit showroom, with someone waiting. That tells you almost nothing about how the mattress will feel on night forty. A 100-day trial at home tells you everything, which is why buying a king size mattress online has become the more careful way to shop this category rather than the riskier one.

The rest shows up in the small decisions: foam densities chosen for durability rather than for a spec sheet, covers selected for airflow in a hot climate, and free delivery to the room the mattress is going into. Support stays reachable after the mattress arrives, which is the part that matters if anything ever goes wrong inside the warranty period.

FAQs

1. What is a standard king size mattress?

A standard king size mattress in India measures 72 inches wide by 78 inches long, which is 6 feet by 6.5 feet. It is the largest of the four common Indian sizes, sitting above single, diwan and queen. The width gives two adults roughly 36 inches each, which is about as much personal space as a single bed offers one person.

2. What are the dimensions of a king size mattress in India?

The dimensions are 72 x 78 inches, or 6 feet wide by 6.5 feet long. You will see the same size written as 72x78, 78x72, 72*78 or 78*72 depending on whether the listing puts width or length first. All refer to the identical product. Always match these to the internal measurement of your bed frame, not its external size.

3. Is a king size mattress suitable for couples and families?

Yes, and it is the size most couples should be buying if the room allows it. Each adult gets around 36 inches of width, which is enough to sleep in different positions without contact. The 78 inch length suits taller adults, and the extra width absorbs a child joining the bed at night without anyone sleeping sideways.

4. What is the difference between a king size mattress and a queen size mattress?

Width is the only difference in Indian sizing. A king is 72 inches wide, a queen is 60 inches, and both are 78 inches long. That 12 inch gap works out to 6 extra inches per person, which is the difference between two adults having personal space and two adults sharing it. A king needs about a foot more wall space in the room.

5. Which king size mattress is best for back support?

An orthopedic memory foam or high-density foam construction is usually the strongest choice for back support, because it holds the lower back in contact with the surface while keeping the hips from sinking. Medium-firm is the firmness most back sleepers do best on. A hybrid with a pocket spring core and a firm comfort layer is the alternative worth testing.

6. What firmness level is ideal for a king size mattress?

There is no single ideal firmness - it depends on sleeping position and body weight. Side sleepers generally do best on medium to medium-soft, back sleepers on medium-firm, and stomach sleepers on firm. Heavier body weights need a firmer surface than lighter ones for the same support. If two people disagree, a flippable dual comfort build solves it.

7. How do I choose the right king size mattress for my needs?

Work through five checks in order: sleeping position, body weight, how warm you sleep, bed frame height, and warranty. Position and weight settle the firmness. Sleeping warm pushes you towards latex, grid or pocket spring rather than memory foam. Frame height settles the thickness. Warranty and the trial period cover you if the shortlist was wrong.

8. How long does a king size mattress typically last?

A well-made king size mattress generally lasts between eight and twelve years, depending on the material and the density of the foam inside it. Latex and high-density foam hold their shape longest. Warranty length is the most reliable guide available to a buyer: Wakefit's ShapeSense Orthopedic Classic carries 10 years and the Infiniti carries 12.

9. How do I maintain and clean a king size mattress?

Use a mattress protector from day one, because it is far easier than cleaning the mattress itself. Vacuum the surface every month or two, spot-clean spills immediately with a barely damp cloth and mild soap, and let it dry completely before making the bed. Air the mattress with the sheets off every few weeks, and never soak it.

10. Why should I buy a king size mattress online from Wakefit?

Buying direct removes the retail margin that normally sits on a mattress, and the 100-day trial replaces a two-minute showroom test with a hundred real nights at home. Delivery is free, no-cost EMI is available, and warranties run to 10 or 12 years on the ShapeSense range. More than 55 lakh customers have already bought a Wakefit mattress.
