Layer Details
Knitted Cover
A soft knitted cover that breathes well, which means heat can escape rather than building up around you. It helps keep you at an even temperature through the night.
Memory Foam
A generous layer of memory foam that uses your natural heat and weight to mould to your body's curves. In practice this means pressure points like hips and shoulders feel cushioned rather than pressed against the surface.
High-density and soft polyester support layers
These polyester layers add further pressure relief and have strong rebound properties, springing back into shape once you move. That should help the mattress keep its feel over time rather than developing body impressions quickly.
1000 Pocket Springs
Up to 1000 springs sit in their own individual fabric pockets, so each one moves independently. This targets support exactly where your body needs it and reduces the ripple effect when a partner shifts position.

Key benefits
- Room to sprawl on your own: At 30cm wider than the UK single, you can sleep diagonally or starfish and still keep the memory foam cushioning under your hips and shoulders.
- Suits a compact double bedroom: We suggest a room of at least 2.4m x 2.8m, so a small second bedroom or loft conversion can take it with space left to walk round.
- Can decide whether the door clears: Being 15cm narrower than the UK double, it can make the difference between a bedroom door that swings fully open and one that catches the frame.
- Calmer for the odd shared night: Each pocket spring moves on its own, which means a visiting partner turning over sends less movement across a bed that is snug for two.
- Easy to find bedding and frames: The UK small double is a standard 4ft size, so fitted sheets and bed frames are simple to source for a rental or spare room.
This size suits you if...
You sleep alone and have outgrown a single, your bedroom is too tight for a double frame to leave walking space around it, or a partner only stays over occasionally rather than every night.
Consider another size if...
You share the bed every night, because a UK small double feels cramped for two regular sleepers. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
Will the Sleepeezee Lasting Memory 1000 UK small double fit in a box room?
It often will. We suggest a room of at least 2.4m x 2.8m for a UK small double, and the UK small double is 15cm narrower than the UK double. Before ordering, measure where the door swings and where any bedside table would go, as that clearance usually decides it in a box room or studio.
Can a couple share the Lasting Memory 1000 small double for guest stays?
For the occasional weekend, yes. The pocket springs move independently, so one guest shifting position travels less across the surface. It is snug for two, though, so for a couple sleeping together nightly the UK double, at 67.5cm each, is the more comfortable option.
What size is the Sleepeezee Lasting Memory 1000 small double in feet?
The UK small double measures 4ft x 6ft 3in, which is 120 x 190cm. That is a standard UK size, so a 4ft bed frame and small double fitted sheets will suit it.
Should I choose the UK single or UK small double Lasting Memory 1000 for a teenager?
If the room allows, the UK small double gives them 30cm more width at the same length. We suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single, so check the floor space you would lose before sizing up.
Is the Lasting Memory 1000 in a UK small double good for a loft conversion?
It can be a sensible fit where sloping ceilings leave little standing room beside a wider bed. The UK small double is 120cm wide, and at 25.5cm deep the mattress sits comfortably on most frames, so check your headroom above the sleeping position as well as the floor measurements.
