Layer Details
- MemorySense Memory Foam. A memory foam comfort layer that moulds to your body, which means pressure builds more slowly at your hips and shoulders as you settle. It's designed to soothe pressure points and ease aches and pains.
- PostureTech Core Support Springs. A spring system using unique shapes and varied tensions, which means firmer support where your body is heavier and gentler give elsewhere. The result is full-body support with pressure relief rather than a uniformly hard base.

- Fits compact rooms: At 90cm wide it leaves room for a desk, wardrobe and floor space in a small bedroom, box room or loft conversion with a narrow footprint.
- Firm support for growing sleepers: The PostureTech springs give firm, varied-tension support, which suits teenagers moving up from a childhood bed and needing proper spinal alignment.
- Pressure relief for lighter bodies: The MemorySense foam layer softens the firm surface, so lighter sleepers still feel some cradle at hips and shoulders rather than lying on top of it.
- Sensible for a spare room: A guest bed spends most of its life unused, and this size keeps a room that doubles as an office workable day to day.
- Two singles where a double won't work: For siblings sharing or a guest room set up with two beds, a pair of UK singles leaves a walkway between them in most rooms.
This size suits you if...
You're buying for one sleeper: a child ready for a proper supportive mattress, a teenager who has outgrown theirs, or an adult in a student room or first flat where the frame came with the tenancy and the mattress didn't. It also suits a spare room that shares its space with a desk, where anything wider would crowd the room. A firm feel with a softer foam top works well across those ages.
Consider another size if...
You're an adult who sprawls in your sleep, or you're furnishing a room a couple will sometimes use. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Will the Sealy Eaglesfield UK single fit a bunk or mid sleeper frame?
The frame size is right: 90 x 190cm is the standard for UK bunk beds, cabin beds and mid sleepers. The thing to check is depth. This mattress is 25cm deep, which is on the thick side for a raised frame, so measure against the safety rail height before buying. Many bunk frames recommend a shallower mattress for the top bunk.
What size room do I need for the Sealy Eaglesfield UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. The mattress itself is 90 x 190cm, and that allowance leaves room to walk round and open drawers. In a child's room competing with toy storage and a desk, the UK single is usually the only size that leaves the floor genuinely usable.
Is the UK single Sealy Eaglesfield a good choice for a teenager?
Yes, with one caveat. The firm PostureTech springs suit a growing back, and the MemorySense foam eases pressure at the hips and shoulders, useful for lighter bodies that can find firm mattresses unyielding. The caveat is length: at 190cm it's fine for most teens, but a very tall sleeper may eventually want the extra 10cm a UK king offers.
Can you fit two Sealy Eaglesfield singles in one guest room?
Often, yes. Two 90cm-wide beds with a walkway between them is a common guest room layout, and it's more flexible for visitors than one larger bed. Measure your room against two mattresses plus space to move between them, and remember our 2.1m x 2.8m suggestion applies to a single bed on its own.
Is a UK single big enough for an adult?
For one adult who sleeps fairly still, yes: 90 x 190cm is the standard UK one-person size and works well in student rooms and first flats. If you turn a lot in the night or you're used to more width, the UK small double is 30cm wider and the same length, and worth the step up where the room allows.
