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.

Key benefits
- Fits compact rooms: At 90cm wide it leaves floor space free in a child's bedroom where the bed competes with a desk, wardrobe and toy storage.
- A sensible depth for raised frames: The 27cm depth sits within the limit most bunk and mid-sleeper frames specify, though you should check your frame's maximum before ordering.
- Grows with a child: The medium feel and zoned PostureTech springs support a growing teenager as readily as a lighter primary-age child, so it should last through the years.
- Guest-ready comfort: The memory foam layer cushions hips and shoulders, which means visiting side sleepers get proper pressure relief rather than a token spare-room mattress.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teenager's first proper mattress, you sleep alone in a compact bedroom or loft conversion where only a narrow footprint fits under the slope, or you're kitting out a spare room or study that doubles as guest space. Allow at least 2.1m x 2.8m of floor space and the UK single slots in with room to move around it.
Consider another size if...
You're a single adult who spreads out in the night, or you share the bed even occasionally. The UK single is 45cm narrower than the UK double, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

FAQ's
Is the Sealy Claremont single suitable for a bunk or mid-sleeper frame?
Usually, yes. At 27cm deep it sits within the depth limit most bunk, cabin and mid-sleeper frames allow, though frames vary, so check the maximum mattress depth your frame specifies, and for a top bunk make sure the guard rail still sits well above the mattress surface.
Is the Sealy Claremont in a UK single a good choice for a child?
For most children and teens, yes. The medium feel gives cushioning without letting lighter bodies sink too far, and the zoned springs keep the spine aligned as they grow. It sits at the pricier end for a child's bed, but it should outlast cheaper foam-only options.
What room size do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough clearance to walk around the bed and open drawers or a wardrobe. In a shared children's room with two singles plus a walkway between them, you'll need considerably more width.
How much smaller is the UK single Claremont than the UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length. If a solo adult sleeper has the space, that extra width makes a real difference to how freely you can turn; we suggest at least 2.6m x 2.8m for the UK double.
