Layer Details
Quilted Cover
The cover and fillings are stitched together into a patterned comfort quilt, which means the top surface feels cushioned and stays in place rather than shifting around. It gives the mattress a soft first touch before you reach the firmer layers below.
Geltex®
Geltex is a gel-infused foam that shapes to your body for pressure relief while remaining breathable, so it shouldn't trap heat the way traditional memory foam can. It sits between you and the springs to soften that firm base.
Pocket Springs
The Chrome has 1,000 individually mounted springs, each sewn into its own fabric pocket so it can move independently of its neighbours. In practice, this means better contouring to your shape and less motion transfer between partners.

Key benefits
- Room to sprawl, alone: At 120cm wide the UK small double is 30cm wider than a UK single, so a solo sleeper can stretch out without giving the room over to the bed.
- Fits where a double won't: That 15cm saving over a UK double is often the difference between a door that clears the bed and one that doesn't in a box room or studio.
- Springs that suit occasional sharing: The 1,000 pocket springs move independently, so when guests share it for the odd night, one person turning over disturbs the other less.
- Cooler in a small room: Compact bedrooms can run warm, and the breathable Geltex layer lets air move through rather than trapping heat against you.
- Standard bedding, no hunting: 4ft is a standard UK size, so small double fitted sheets are easy to find, and the 26cm depth works with ordinary ones.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're furnishing a guest room or holiday let where couples stay for the odd night rather than every night, or you're downsizing and the bed has to fit the new room. The firm feel rewards back and front sleepers in particular.
Consider another size if...
You share the bed every night, or you're a lightweight side sleeper who'd feel this firm surface at the shoulder on a narrower footprint. Nightly couples should take the UK double instead, allowing at least 2.6m x 2.8m of room.

FAQ's
Is a small double Sealy Enhance Chrome big enough for a couple?
For occasional nights, yes. At 120cm wide the UK small double gives a visiting couple enough room, and the 1,000 pocket springs keep one person's movement from travelling across the bed. For sharing every night it feels tight, and we'd point regular couples to the UK double, which is 15cm wider.
What room size do I need for the small double Sealy Enhance Chrome?
We suggest at least 2.4m x 2.8m. That leaves enough walking space around a 120 x 190cm mattress to open drawers and change the sheets without shuffling sideways. In a box room or loft conversion, that narrower footprint is often what lets the door still clear the bed frame.
Is the UK small double a good upgrade from a single for a teenager?
It's a sensible step. The UK small double is 30cm wider than a UK single but exactly the same length, so it adds sleeping space without eating further into the floor. The firm feel suits a growing back or front sleeper, although a very light side sleeper may find it a little solid.
How much smaller is the small double than a king in this mattress?
The UK small double is 30cm narrower and 10cm shorter than the UK king. In practice that's the gap between a bed built for two people every night and one built for a solo sleeper or occasional guests. If you're over 6ft and sleep stretched out, the extra length of the UK king matters.
Does the firm feel of the Sealy Enhance Chrome change in the small double?
No, the firmness is the same across every size, with the same Geltex layer over 1,000 pocket springs. What changes is how you use it: sleeping alone on 120cm of width, you can shift position freely, which makes a firm surface easier to live with than it would be for two nightly sharers.
