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 spread out: The UK king is 15cm wider than the UK double, which means 7.5cm more space each before elbows and knees start to meet in the middle.
- Fewer early-morning wake-ups: Each spring sits in its own pocket, so when one of you gets up before dawn the other feels only a little of the movement.
- Length for taller partners: At 200cm (6ft 6in) long, the UK king adds 10cm over the UK double, a relief if one of you is tall and used to feet hanging off the end.
- Space for extra pillows: During pregnancy, or while recovering from an injury, there's room for a body pillow on one side without squeezing the other sleeper towards the edge.
- Fits more rooms than a super king: We suggest a room of at least 2.7m x 2.9m, noticeably less demanding than the 3m x 2.9m we suggest for the UK super king.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, or one of you is tall and your different alarm times keep disturbing the other.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Lasting Memory 1000 UK king big enough for two adults?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than the UK double. If you both sprawl, or a child or dog regularly joins you, the UK super king gives 90cm each, although it needs a larger room.
Will I feel my partner moving on a Lasting Memory 1000 king size?
Less than you might expect. The pocket springs move independently, so a partner turning over or getting up early sends only a slight ripple across the bed. The UK king's 150cm width also puts a little more distance between you than a UK double, which helps if you keep very different hours.
Is the Lasting Memory 1000 UK king long enough for someone over 6ft?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double, the UK small double and the UK single. For a partner over six foot that extra length is often the real reason to upgrade, because it lets you lie straight with a pillow behind you.
Should I get the Lasting Memory 1000 in a UK king or a UK super king?
Both are the same length, so the choice comes down to width and room. The UK king gives 15cm less each than the UK super king, but we suggest at least 2.7m x 2.9m for the UK king against 3m x 2.9m for the UK super king. If your room is tight, choose the UK king.
Will a Lasting Memory 1000 UK king fit in a new build master bedroom?
Often, but measure once the wardrobes are in, because fitted furniture takes more floor than the plans suggest. Allow at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m giving comfortable space to walk round both sides and open drawers.
