The Sealy Claremont pairs MemorySense foam, which moulds to your body for pressure relief, with Sealy's PostureTech spring system, which spreads your weight evenly and gives zoned support where you need it most. That combination suits most back and side sleepers who want cushioning without sinking too far. It comes in UK Single, Double, King and Super King. Furniture Village, which lists it, states a 20-year structural guarantee, a reassuringly long span, although those terms are the retailer's rather than confirmed by Sealy directly.

Why should you choose this mattress?
Choose the Claremont if you want the contouring feel of memory foam but worry pure foam might feel too enclosed. The springs underneath add bounce and airflow that all-foam designs can lack, which means turning over feels a little easier and the bed sleeps slightly cooler than foam alone. The medium firmness is a sensible middle ground: soft enough for side sleepers to settle into, supportive enough for most back sleepers. It sits at a fair price for a hybrid-style build from an established name, and the retailer-listed 20-year guarantee is longer than most brands offer. Furniture Village also mentions EdgeGuard edge support, though the listing gives little detail on it.
Key features & layer details
Cover
A knit fabric cover with a smooth quilted surface. It gives a soft first touch before you reach the comfort layers beneath.
Memory foam
MemorySense foam that moulds to your body for targeted comfort and pressure relief. In practice this means less pressure on your hips and shoulders, especially if you sleep on your side.
Spring system
Sealy's PostureTech spring system distributes your weight evenly and provides zoned support. That helps keep your spine aligned and stops heavier areas sinking too deeply.

Best suited for?
Side sleepers
MemorySense foam moulds to your body and eases pressure at the hips and shoulders, while the medium feel lets you settle in comfortably.
Back sleepers
Zoned support from the PostureTech springs, with medium firmness, gives enough support for lying on your back without feeling hard.
Combination sleepers
Springs under the memory foam add bounce and airflow, which means turning over feels easier than it can on an all-foam mattress.
Couples
Available up to Super King, the Claremont has springs that spread weight evenly, so two people of different builds are both supported.
If you like a properly firm, stay-on-top feel, the medium rating and memory foam layer will likely feel too cushioned. Hot sleepers who react badly to memory foam's hug may also want to look elsewhere, as may anyone who needs their mattress quickly: the listed delivery window is up to five weeks.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Sealy Claremont mattress firm or soft?
It's rated medium. That suits most back and side sleepers: the MemorySense memory foam cushions pressure points while the PostureTech springs keep you supported. Lighter sleepers should find it comfortably yielding, but if you prefer a very firm surface it may feel a little too soft.
How deep is the Sealy Claremont mattress?
It's 27cm deep, which is a generous depth that should work with standard fitted sheets. The height comes from a layered build of memory foam over a full spring system.
Does the Sealy Claremont have a guarantee?
Furniture Village states a 20-year structural guarantee. That's the retailer's stated term rather than one confirmed on Sealy's own page, so it's sensible to check the guarantee conditions wherever you buy.
How much does the Sealy Claremont cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It's available in UK Single, Double, King and Super King.
How long does delivery of the Sealy Claremont take?
Furniture Village lists delivery within 5 weeks, with a paid Premium Delivery Service for mattresses that includes safe delivery to your room. These are the retailer's own terms, so timings may differ if you buy elsewhere.
