Best mattress for heavy people (UK)

What changes when you're a heavier sleeper

More weight pushes deeper through a mattress, so depth, firm support and strong edges matter more than the comfort layer on top. On a thin or soft mattress, a heavier sleeper passes through the comfort layer quickly and rests on the support core. That can feel hard in some places and saggy in others.

• Depth. Around 25cm or more gives the springs and comfort layers room to work before you reach the base. When we checked on 16 October 2026, 174 of the 252 firm and extra-firm mattresses we compare with a stated depth were 25cm or deeper. Of those, 63 were 30cm or more. Every pick below is at least 25cm.
• Firmer tension. A heavier body compresses any mattress more, so one labelled firm often feels closer to medium firm. Our firm and extra firm ranges are where most heavier sleepers should start.
• Pocket springs. Individually wrapped springs push back where you press hardest and spread the load, which is why every pick here uses them. Our open coil vs pocket sprung comparison explains the difference.
• Reinforced edges. Rod edges, firmer outer springs or foam side walls stop the sides collapsing when you sit on the bed to dress.

Memory foam isn't ruled out, but deep, soft foam is the construction most likely to let the hips sink. If you prefer the foam feel, choose a firm build with a dense base.

How we chose these seven

We picked these seven by comparing depth, spring construction, edge support, firmness and guarantee terms across the UK market. We haven't slept on them. The comparison is based on each manufacturer's or retailer's specification, verified owner reviews where they exist, and how each one compares with similar mattresses.

We ordered them by weighing depth, firm support, edges and guarantee length against price. That's why the cheaper Rock Hard Mega Firm sits second, and the Premium Gold, with its one-year guarantee, comes last. What we earn plays no part in which mattresses appear or where they sit.

Heavy sleeper picks at a glance

Here's how the seven compare on the details that matter most at higher weights. The trial column shows whose trial it is.

The best mattress for heavy people: our seven picks

The Sleep Story Ortho 2000 is the best mattress for heavy people for most buyers, with the Rock Hard Mega Firm 1500 the one to choose if budget comes first.

1. Sleep Story Ortho 2000: the long-guarantee pick

Sleep Story is Furniture Village's own brand, and the Ortho 2000 puts 2,000 pocket springs into a king size, which help keep your spine level. DynamicEdge side support means you can use the full width of the bed, and at 30cm it's one of the deepest picks here. Furniture Village describes the filling as hypoallergenic.

Rated extra firm, it's backed by a 20-year guarantee, matched here only by the Village Luxury 4850, at a mid-range price. Furniture Village doesn't state a trial for it, so check before you order. Side sleepers and lighter bodies are a poor match, since their shoulders and hips need to sink in a little. Against the Rock Hard Mega Firm, you pay more for 5cm of extra depth and four times the guarantee. See the Sleep Story Ortho 2000

2. Mattress Online Rock Hard Mega Firm 1500: the value pick

Mattress Online makes this own-brand mattress by hand in the UK, and it does what the name suggests. Its 1,500 pocket springs respond individually, so you get firmer pushback where you're heavier, and steel piping around the edge helps the sides hold their shape. At 25cm deep and rated firm, it was the cheapest pick here in a double when we checked on 16 October 2026.

Across owner reviews on Mattress Online, buyers describe a very firm, supportive surface with minimal dipping. There's no thick comfort layer, so side sleepers, particularly lighter ones, will likely find it too firm at the shoulder and hip. Mattress Online gives it a 100-night trial and a 5-year guarantee, which matters with a feel this firm. Against the Premium Gold 2000, it's 4cm shallower and a step down in firmness, but its guarantee runs five years against one. See the Rock Hard Mega Firm 1500

3. Otty Extra Firm Hybrid: the flippable pick for over 15 stone

Otty recommends this mattress for people over 15 stone (95kg), which gives you a clear figure to check against. High-density foam sits over up to 2,000 encapsulated pocket springs to hold your spine level, and thick foam side supports make the full width usable. You can flip it, and Otty rates one side 9 and the other 10 on its 10-point firmness scale.

At 25cm deep, it comes with a trial of up to 100 nights and a 10-year guarantee from Otty, at a mid-range price. Both sides are deliberately firm, so there's no softer side to fall back on, and side sleepers, especially lighter ones, should look elsewhere. Compared with the Sleep Story, you get a shorter guarantee but two firmness options in one mattress. See the Otty Extra Firm Hybrid

4. Village Luxury 4850: the deepest pick

At 33cm, this is the deepest mattress here. Cotton, wool, silk and cashmere make up the fillings, which Furniture Village says breathe well and manage moisture. Pocket springs and micro springs sit in seven zones, so your hips can sink slightly more than your shoulders. A double steel-framed edge reinforces the sides, and Furniture Village backs it with a 20-year guarantee.

Rated firm, it sits at a premium price. Delivery can take up to five weeks, so order well ahead, and no trial is stated. If you prefer memory foam's slow, sinking hug, this might not be the best choice. Against the Sleep Story, you pay more for natural fillings and extra depth with the same guarantee. See the Village Luxury 4850

5. Hypnos Honley Extra Firm: the extra-firm pick for warm sleepers

The Honley gets its extra-firm feel from 1,000 pocket springs and fibre layers instead of dense foam, so it should feel supportive without sleeping hot. Three outer rows of firmer-gauge springs stiffen the edges, and the wool fillings carry Responsible Wool Standard certification. At 30cm deep, it comes from a National Bed Federation Approved brand.

Mattress Online lists a 100-night trial and a 10-year guarantee, and it sits at a premium price. Being single-sided, it can't be flipped, and lighter side sleepers will find too much pressure at the shoulders and hips. If you sleep warm and want extra firm, it's the one to pick over the Otty, which uses a foam layer. See the Hypnos Honley Extra Firm

6. Sleepeezee Wool Luxe 1200: a traditional firm feel

Sleepeezee's Wool Luxe layers British wool and silk over 1,200 pocket springs, with Caliber edge support that keeps the sides usable right to the edge. Wool and silk breathe, which helps if you also sleep warm. Rated firm and 25cm deep, it carries a 10-year guarantee from Sleepeezee at a mid-range price, and trial terms depend on the retailer.

Lightweight partners and dedicated side sleepers may find it presses on the shoulder and hip, and it uses wool and silk, so skip it if you avoid animal-derived materials. Next to the Hypnos Honley, it's 5cm shallower and a step down in firmness. See the Sleepeezee Wool Luxe 1200

7. Mattress Online Premium Gold 2000 Extra Firm: deep, with a short guarantee

Step up to 2,000 pocket springs and 29cm of depth, with a wire rod edge so the sides shouldn't sag. Rated extra firm, it was the second-cheapest pick here in a double when we checked on 16 October 2026, which is a lot of depth for the money. Across owner reviews on Mattress Online, buyers say the surface holds its shape on all sides, though some feel the edge could be better when sitting on it.

The catch is the guarantee: one year, against five for the Rock Hard Mega Firm and twenty for the Sleep Story. Mattress Online gives it a 100-night trial, which lets you judge the feel, but weigh that guarantee if you want a mattress for the long haul. Lightweight side sleepers should look elsewhere. See the Premium Gold 2000 Extra Firm

Check the base and bed frame as well as the mattress

A firm mattress on a weak base won't stay firm for long, because slats that bow or sit too far apart let it sag between them. That wear can look like the mattress failing. Before you buy, check the bed you already own:

• The frame's stated weight limit, which should cover everyone who sleeps in it.
• Slat spacing and a central support rail. Read the mattress guarantee too, since some set conditions on the base.
• The age of the base. An old divan with tired springs undermines a new mattress from underneath.

If a maximum weight per sleeper matters to you, ask the brand or retailer before ordering, and keep the answer in writing.

Signs your current mattress isn't coping

A mattress that's losing the fight usually shows a dip where your hips rest, which you can see when you strip the bed. Edges that fold when you sit on them and springs you can feel through the surface point the same way, as does waking stiff after a full night's sleep. If your mattress is several years old and shows two or more of these, a replacement built for your weight will usually do more than a topper.

Guarantees: what's covered, and for how long

Guarantees on the picks here run from one year to twenty, and a longer one gives you more years of cover against faults. Most cover manufacturing faults and body impressions deeper than a set measurement, rather than the gradual softening every mattress goes through, so read what counts as a fault. That length is worth more to a heavier sleeper than to most.

Sharing a bed with a lighter partner

A firm mattress that suits you can feel hard to a lighter partner, who may be happier on medium firm. Some couples in larger sizes choose two single mattresses zipped together so each side gets the firmness it needs, and our mattress sizes guide shows which sizes allow that. If either of you has back pain, our guide to the best mattress for back pain covers the research on medium-firm versus firm.

For budgets under £500 in a double, the best budget mattress guide includes a firm option, and the mattress buying guide covers the rest of the decision, from sizes to trials.
