Layer Details
- Top layer. A body-contouring memory foam layer that moulds to your shape, which means personalised comfort at every point of contact. You'll feel a gentle cradling rather than lying on top of the mattress.
- EcoFoam® layer. A recycled, breathable EcoFoam® layer that lets your heaviest pressure points dip slightly into the surface. This helps position your back properly, and the breathability keeps things a little cooler than solid foam alone.
- Pocket springs. Up to 1000 individually pocketed springs that move independently, which means support targeted to key areas of your body rather than the whole bed shifting when you do. They deliver the medium-firm feel.
- Border. A foam-encapsulated border that maintains the mattress's structure right to the edge. You can spread out and use the full surface without a soft, saggy perimeter.

- Proper space for two: At 75cm each for two people sharing, you both get room to stretch out rather than negotiating a shared middle.
- Less partner disturbance at this width: The 1000 pocket springs move independently, and with 75cm each an early alarm on one side is far easier to sleep through.
- Extra length for taller sleepers: The UK king runs to 200cm, so anyone approaching six foot gets their feet on the mattress rather than hanging off it.
- Usable edges matter more when sharing: The foam-encapsulated border keeps support firm to the perimeter, so the full 150cm is genuinely sleepable, useful when a dog claims the middle.
- A kinder price for the upgrade: King sizes usually carry a premium, but this hybrid sits in budget territory, making the move up from a double less painful.
This size suits you if...
You share the bed every night and have outgrown a double, you or your partner keep different hours and want movement on one side to stay on that side, or someone in the bed is approaching six foot and needs the 200cm length. Your bedroom can spare at least 2.7m x 2.9m, our suggested minimum for a UK king.
Consider another size if...
Your room falls short of 2.7m x 2.9m, or you mostly sleep alone. We'd recommend the UK double of this mattress instead, which needs at least 2.6m x 2.8m and still gives two sharers 67.5cm each.

Is the Simply Memory Pocket 1000 in a UK king good for couples on different schedules?
It's a sensible fit. The pocket springs compress individually rather than shifting the whole surface, and the UK king's 75cm per person adds physical distance on top. If one of you leaves for work hours before the other, the combination makes those early exits much less disruptive than they would be on a narrower mattress.
Is the UK king version long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than the UK double, and that difference is usually the point for taller sleepers. Length, rather than width, is often the real upgrade here. Someone comfortably over six foot may still find their feet near the edge, but most people around that height will fit properly.
How much space do two people get on the UK king Simply Memory Pocket 1000?
You get 75cm each for two people sharing, compared with 67.5cm each on the UK double, so the UK king gives 7.5cm more per person. That sounds small on paper, but it's the difference between turning over freely and nudging your partner every time you move.
What room size does this mattress need in a UK king?
We suggest at least 2.7m x 2.9m for a UK king, which allows walking space around the bed once it's in. Measure with wardrobes and drawers in place, as a new build master bedroom can feel far tighter than the floor plan implies. If you're short of that, the UK double needs at least 2.6m x 2.8m.
Should I go for the UK king or hold out for a super king?
MattressNextDay doesn't offer this mattress in a super king, so the UK king is the largest size available here. For comparison, a UK super king is 30cm wider and gives 90cm per sharer, but it also demands a room of at least 3m x 2.9m. For most couples, the UK king is the practical ceiling anyway.
