Layer Details
Pillow Top
An additional layer of plush fillings sewn onto the top, which means a softer initial feel when you lie down. You get cushioned comfort without changing the medium firm support underneath.
Knitted Cover
A soft knitted cover that's breathable, helping to keep you at an even temperature through the night.
Body-Contouring Memory Foam
Super-soft memory foam that adapts to your shape, easing pressure on your joints. Its slow response minimises bounce, so you're less likely to feel a partner moving.
Soft Polyester Comfort Layers
Soft polyester layers that add cushioning without compromising the medium firm feel.
High-Density Polyester Support Layer
A denser polyester layer beneath the comfort fillings, which helps the mattress hold its structure and last longer.
4000 Pocket Spring System
1000 traditional pocket springs combined with 3000 mini comfort springs. Each spring moves independently, which means support that follows your body rather than pushing back as one flat surface.

Key benefits
- Space to share without crowding the room: At 135 x 190cm, the UK double leaves floor space for a wardrobe and drawers in a second bedroom or first flat, where a UK king would start to crowd them out.
- Quieter nights on a closer-quarters bed: With 67.5cm each, you lie nearer your partner than on a larger size, so the slow-response memory foam, which dampens movement, matters more on a UK double.
- Bedside tables can usually stay: We suggest at least 2.6m x 2.8m for a UK double, so a typical master bedroom can often keep a bedside table on both sides of the bed.
- A manageable rotate: The pillow top means you rotate this mattress rather than flip it, and turning a UK double head to foot is an easier two-person job than turning a UK super king.
- A proper shared bed for guests: In a spare room, a UK double gives visiting couples a real shared bed, and the medium firm feel should suit most of the people you invite to stay.
This size suits you if...
You share the bed with a partner in a bedroom of ordinary size and want to keep space for your furniture, you're fitting out a guest room for couples who visit, or you sleep alone and like room to stretch out while a cat or dog claims the corner.
Consider another size if...
You and your partner both sleep spread out, or one of you is tall. We'd recommend the UK king instead, which gives 75cm each and 10cm more length; we suggest at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on a Sleepeezee Memory 4000 UK double?
Two people sharing the UK double get 67.5cm each. That is 7.5cm less each than the UK king, which gives 75cm per person. The memory foam layer helps here, because its slow response absorbs movement, so a partner rolling over close by is less likely to wake you.
Will a Sleepeezee Memory 4000 UK double fit my bedroom with bedside tables?
We suggest a room of at least 2.6m x 2.8m for the UK double, with around 3m x 3m feeling comfortable. At that size, most rooms can take a bedside table on each side and still leave space to walk round the bed. Measure your room before you compare prices.
Is the Sleepeezee Memory 4000 UK double long enough for tall sleepers?
The UK double is 190cm long, or 6ft 3in, which suits most adults. If you or your partner are tall enough that your feet reach the end, the UK king is 10cm longer, and the UK super king shares that longer length too, although both need a larger room.
Sleepeezee Memory 4000 double or king for a couple who toss and turn?
The memory foam limits how much movement travels across either size. On the UK double, though, you have 67.5cm each, so restless sleepers can bump into each other. The UK king gives 75cm each and needs at least 2.7m x 2.9m, which we'd suggest if your room allows it.
Is the Sleepeezee Memory 4000 in a UK double too big for one person?
For a solo sleeper, the UK double is 45cm wider than the UK single, which gives you room to spread out or share with a pet. The UK single only makes more sense if your room is small; we suggest at least 2.1m x 2.8m for it.
