Layer Details
Memory Foam
A memory foam layer that cradles to your unique shape, which means a cushioned, cosy feel as you settle in. It's the layer doing the pressure-relief work.
Pocket Springs
1000 individual springs, each encased in its own cloth pocket, adapting to movement to give personalised support across your body. Because the springs move independently, you should feel less disturbance when a partner shifts.
Layer details from mattressonline.co.uk product page, September 2026.
Key benefits
- 75cm each, every night: Two people sharing get 75cm of width each, which means room to change position without negotiating for territory.
- Distance plus independent springs: The 1000 pocket springs move independently, and in a UK king your partner is further away too, so an early alarm is less likely to wake you.
- Length for taller sleepers: At 200cm long, the UK king gives 10cm more length than the UK double, a real relief if either of you is approaching 6ft.
- A gentle-priced upgrade: The Memory Zone sits in the value bracket, so moving up to a UK king costs less here than with most premium hybrids.
- Memory foam across a wider surface: The memory foam layer cradles hips and shoulders wherever you settle, useful when the extra width tempts you to sprawl.
This size suits you if...
You share the bed every night and a double has started to feel cramped, or one of you keeps waking when the other gets up hours earlier. It also suits couples where one partner is tall, since the 200cm length removes the dangling-feet problem, and anyone whose dog has quietly claimed a third of the mattress.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. Solo sleepers would be well served by the UK double, which gives generous space for one; allow at least 2.6m x 2.8m for it.

FAQ's
Is the Memory Zone 1000 Pocket in a UK king big enough for a couple?
Yes, comfortably for most. Two people sharing get 75cm of width each, which is 7.5cm more each than a UK double provides. Combined with pocket springs that absorb movement independently, that space makes a noticeable difference if one of you fidgets or keeps different hours.
Will a king size Memory Zone fit in my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round and open drawers. New build master bedrooms can be tighter than they look once wardrobes go in, so measure the usable floor rather than the room on the plan.
Is the UK king Memory Zone long enough for someone over 6ft?
At 200cm, the UK king is 10cm longer than the UK double, so a sleeper around or over 6ft gets meaningful clearance rather than feet at the edge. If length is your only reason for upgrading, the UK king delivers it without the room demands of the UK super king.
Should I get the Memory Zone in a king or a super king?
The UK super king is 30cm wider, giving 90cm each for two sharing against the UK king's 75cm, and both are the same length. The catch is space: we suggest at least 3m x 2.9m for the UK super king. If your room is average sized, the UK king is the safer call.
