Layer Details
Cover
A knitted fabric cover with a smooth quilted surface. It gives the sleeping surface a soft, finished feel before you reach the firmer layers below.
Filling
A layer of Geltex, a gel-infused foam that offers pressure-relieving comfort and breathability. In practice this means gentle cushioning at the surface and better airflow than traditional foam, helpful if you tend to sleep warm.
Springs
The king size contains 1,000 individually pocketed springs delivering firm support and reducing movement transfer. Each spring responds separately, so the mattress contours to your shape and limits partner disturbance.

Key benefits
- A width that leaves the room usable: At 90cm wide, this UK single leaves space for a desk, wardrobe and floor to play on in a compact child's bedroom.
- Firm support for growing sleepers: The firm pocket spring build suits back and front sleepers, and gives children and teens a stable, supportive surface rather than a sink-in one.
- Geltex softens the top: A layer of gel-infused foam over the springs eases shoulders and hips a little, so the firm feel doesn't read as hard.
- Check it against raised frames: At 26cm deep it's on the taller side, so measure the guard rail height before pairing it with a bunk or mid sleeper.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and they're the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager who needs firm, supportive sleep in a room where every inch matters, you're kitting out a spare room or study that doubles as guest space, or you're a single adult in a first flat or student room where only a 90cm footprint will fit.
Consider another size if...
You're an adult who shares the bed, or a restless solo sleeper who wants room to spread out. We'd recommend the Sealy Sterling in a UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m for it.

FAQ's
Will the Sealy Sterling UK single fit a bunk bed or mid sleeper?
It fits the standard 90 x 190cm frame size, but check the depth. This mattress is 26cm deep, which is taller than many mattresses sold for raised frames, so measure your bunk's guard rail first. Safety guidance generally requires the rail to sit well above the mattress surface, so a slimmer mattress may be the safer pick for a top bunk.
Is the Sealy Sterling UK single a good choice for a child's bedroom?
Yes, with one caveat. The firm pocket spring support suits growing backs, and the 90cm width leaves floor space free for a desk and toy storage in a small room. The caveat is the firmness itself: a very light child who sleeps on their side may find it a little unforgiving at the shoulder and hip.
What room size do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space, which is our own guidance rather than Sealy's. That allows you to walk alongside the bed and open a wardrobe. It also means two UK singles can work in a shared children's room or a twin guest room, provided you keep a walkway between them.
How much smaller is the UK single than the UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length at 190cm. That 45cm is the difference between a one-person bed and one a couple can share, but it's also the difference between a bed that fits a box room and one that dominates it.
Does the firm feel change in the single size?
No, the Sealy Sterling is firm across every size, with the same Geltex layer softening the surface. What changes with the UK single is who it suits: it's the size for one sleeper, so partner disturbance isn't a factor here, and the pocket springs simply contour to a single body's shape.
