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.

- Real room for one: At 120cm wide you get 30cm more than a UK single, which means a solo sleeper can change position freely without an arm hanging off the edge.
- Fits the smaller bedroom: Being 15cm narrower than a UK double, it can leave walking space in a box room or loft conversion where a bigger frame would block the door.
- Firm support in a compact footprint: The PostureTech springs give firmer resistance where your body is heavier, so a lighter frame size does not mean lighter support.
- Foam comfort where you actually lie: The MemorySense layer moulds slowly around hips and shoulders, easing pressure at the points a solo sleeper settles into night after night.
- Copes with occasional sharing: Two people can manage the odd night together, which makes this size a practical pick for a guest room that mostly hosts one visitor.
This size suits you if...
You're a solo adult who has outgrown a UK single but your room cannot spare the width of a UK double, or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly. It also suits a teenager moving up from a single without giving up floor space, provided they like a firm feel with slow-moulding foam on top.
Consider another size if...
You share the bed every night, because 120cm across two adults leaves little space to move on a foam surface you sink into. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room for it.

Is the Sealy Eaglesfield small double big enough for a couple?
For occasional nights, yes. For every night, we'd hesitate. The UK small double is 15cm narrower than a UK double, and memory foam holds you where you settle rather than letting you shuffle easily, so two adults will notice the squeeze. As a guest bed for visiting couples it works well; as a permanent shared bed, size up.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves enough room to walk around the bed and open drawers without turning sideways. It is our own guidance rather than Sealy's, and if your room is tighter than that, measure the walkways before committing rather than after delivery.
Should I get the Sealy Eaglesfield in a small double or a double?
It comes down to your room. The UK small double is 15cm narrower than the UK double, and both are the same length, so the choice rarely affects taller sleepers. Sleeping alone in a compact room, take the small double. Sharing regularly, or with space to spare, the UK double is the better long-term buy.
How much bigger is the small double than the single Eaglesfield?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is the whole point of this size: it turns a bed you fit on into one you can stretch out across, without demanding much more floor space than a single frame.
Will a small double fit in a loft conversion or box room?
Often, yes, and this is where the size makes most sense. At 120cm wide it can sit under a sloped ceiling or against a short wall and still leave standing room beside it, where a UK double would not. Measure the usable floor, allow for our suggested 2.4m x 2.8m minimum, and check the door still clears.
