Layer Details
Memory Foam
The top layer is memory foam that lets air and moisture pass through, which means heat is drawn away rather than trapped. You get the contouring feel of memory foam with less of the warmth it's known for.
White fibre filling
Beneath the foam sits a white fibre filling that cushions the movement of the springs, so you feel a smooth surface rather than individual coils. It also helps reduce allergens, a quiet bonus for sensitive sleepers.
Pocket Springs
The base layer holds 1000 pocket springs, each moving independently to adjust to your body shape. This independence is also what lets the mattress flex properly on an adjustable base.

Key benefits
- Room to spread out on your own: At 30cm wider than a UK single, you can raise the head section to read and still roll onto your side without finding the edge.
- Kinder to a small floor plan: Being 15cm narrower than a UK double leaves a little more space beside the frame, which helps in a loft conversion where the sloping ceiling limits where you can stand upright.
- A soft feel with space to use it: Sleepeezee rates it Medium-Soft, so a solo side sleeper gets a cushioned surface and the full width to curl up however they like.
- Good for occasional couples: Two people can share comfortably for a weekend visit, so it makes a sensible guest room choice if that room already has an adjustable base.
- Easy to dress: The UK small double is a standard 4ft size, so fitted sheets and frames are straightforward to find on the high street.
This size suits you if...
You sleep alone but like room to sprawl, your bedroom can't comfortably take a full double, or you're kitting out a guest room where a couple stays only once in a while.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
What size is the Sleepeezee In-Motion Memory Pocket 1000 UK small double?
The UK small double is 120 x 190cm, which is 4ft x 6ft 3in in imperial. It's 30cm wider than the UK single and 15cm narrower than the UK double, with all three sharing the same length.
Will a UK small double mattress fit my adjustable bed base?
Only if the base is also a UK small double, so check that your adjustable frame is made for a 120 x 190cm mattress. A mattress sized for a different frame won't sit correctly as the sections move, and the springs are designed to flex with a base that matches.
What room size do I need for a UK small double adjustable bed?
We suggest allowing at least 2.4m x 2.8m. If you're downsizing to a flat, measure the new bedroom rather than relying on what fitted in the old one, and remember an adjustable frame needs clearance for the head section to rise without catching a wall or window sill.
Can two people sleep on the Sleepeezee In-Motion UK small double?
Yes for the odd night, but it's a squeeze for nightly sharing, especially with the softer feel letting you roll towards each other a little. For a couple every night, the UK double gives 67.5cm each, and we suggest at least 2.6m x 2.8m for the UK double.
Sleepeezee In-Motion UK small double or UK double for one person?
For one adult, the UK small double is usually plenty, and being 15cm narrower than the UK double makes it easier to fit into a tight room. Choose the UK double if your room clears 2.6m x 2.8m comfortably and you'd rather have the extra width.
