Layer Details
Pillowtop
A sumptuous pillowtop layer sewn onto the surface, which means the first thing you feel is soft cushioning rather than the springs. It gives the mattress its plush, welcoming character.
Geltex
Geltex is a breathable comfort material that offers personalised pressure relief, which means it moulds to your shape without the warm, sunken feel some foams create. Airflow through this layer helps keep the sleep surface cooler.
Pocket springs
Body-responsive pocket springs provide gentle support and reduce movement transfer between partners. Furniture Village specifies 1,000 springs in the king size, though counts for other sizes aren't stated.

Key benefits
- Fits compact rooms: At 90cm wide it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or two beds with a walkway between them where siblings share.
- A softer feel for growing sleepers: The pillowtop gives a cushioned, medium surface with pocket springs underneath, a forgiving combination for teenagers who sleep on their side.
- Cool for one sleeper: Geltex lets air move through the comfort layer, which means a solo sleeper is less likely to overheat than under traditional memory foam.
- Guest room friendly: In a spare room that doubles as an office, or a guest room with two beds rather than one, the UK single keeps the floor usable between visits.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for one person: a child moving up from a cot bed, a teenager, or an adult sleeping solo who likes a softer surface. It also makes sense for a guest room or a spare room that spends most of the week as an office, and it suits a student flat or first rental where the frame is provided and the mattress isn't.
Consider another size if...
You're an adult who shares the bed regularly, or you have the space for more stretching room. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
What size is the Sealy Ashton UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any ordinary single bed frame, standard single fitted sheets and a 135 x 200cm single duvet without any hunting for odd dimensions.
Can I use the Sealy Ashton UK single on a bunk or mid sleeper?
Be careful here. The Ashton is 32cm deep, which is taller than most bunk and mid-sleeper frames allow: a deep mattress can raise a child above the safety rail on the top bunk. Check your frame's maximum mattress depth before buying, as many raised frames are designed for slimmer mattresses.
Is the Sealy Ashton single a good mattress for a child or teenager?
The medium feel and pillowtop suit lighter bodies, since a lighter sleeper sinks in less and gets the cushioning without feeling swallowed. The Geltex layer breathes well too, useful for teenagers who run warm. If your child prefers a firm, taut surface, this isn't that.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk alongside the bed and open drawers or a wardrobe. At 90cm wide, the UK single is also the practical choice under a sloped loft ceiling, where only a narrow footprint fits usable headroom.
How much bigger is the double than the single Sealy Ashton?
The UK double is 45cm wider than the UK single and the same length, so you gain width rather than legroom. For the UK double we suggest a room of at least 2.6m x 2.8m. Depth, feel and construction are identical across sizes; only the footprint changes.
