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.

- 90cm of your own: Each sleeper gets 90cm, which means you can stretch out or curl up without edging into your partner's half.
- Distance plus independent springs: Pocket springs limit the ripple when someone shifts, and at this width the movement has much further to travel before it reaches you.
- Room for small visitors: If a child climbs in at 3am, a 6ft x 6ft 6in surface leaves everyone a usable share rather than two adults clinging to the edges.
- Space for a dog as well: If a large dog sleeps on the bed every night, the extra width stops it from pushing either of you to the edge.
- Less shared warmth: Memory foam responds to body heat, and keeping two bodies further apart can help if you run warm, although the foam itself may still feel slightly cosy.
- In proportion in a large room: In a spacious period bedroom or a generous master, a UK king can look a little lost, whereas a UK super king fills the space in proportion.
This size suits you if...
You share with a partner who tosses and turns and a smaller bed has stopped being enough, or your bed regularly fills up with children or a large dog, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or you want extra space without losing floor around the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee Lasting Memory 1000 super king worth it over the king?
If you have the room, the UK super king is 30cm wider than the UK king and the same length, giving each sleeper 15cm more. That mostly helps with a restless partner or a child climbing in. The UK king needs at least 2.7m x 2.9m, compared with our suggested 3m x 2.9m for the UK super king.
How much space do two people get on the Lasting Memory 1000 super king?
Each person gets 90cm on the UK super king. That extra distance helps the pocket springs, because a partner's movement starts much further from you. If a disturbed night is the main problem, the width will make more difference than any change to the comfort layer.
Is the Sleepeezee Lasting Memory 1000 super king big enough for two adults and a child?
For occasional night-time visits, yes: 180 x 200cm leaves room for a small child between two adults without anyone ending up on the edge. If two children join you most nights, the bed will still feel crowded. That is simply the limit of the largest standard UK size, not a flaw in this mattress.
How much bigger is the Lasting Memory 1000 super king than a double?
The UK super king is 45cm wider and 10cm longer than the UK double. Couples gain 22.5cm each, as the UK double gives 67.5cm per person. The room needs more space too: we suggest at least 2.6m x 2.8m for the UK double against 3m x 2.9m for the UK super king.
Will the Lasting Memory 1000 feel warm with two people in a super king?
It should feel a little cooler than sharing a smaller size, because 90cm each keeps your body heat further from your partner's. The memory foam still moulds using warmth, so very hot sleepers may notice some heat on their own side. The breathable knitted cover helps, but it won't match an all-spring design.
