Layer Details
Graphite memory foam
A memory foam layer with cooling graphite that helps relieve pressure and regulate temperature. It adds cushioning over the firm feel and helps limit heat build-up.
Individually wrapped pocket springs
Individually wrapped springs sit beneath the memory foam. Each spring works on its own, which helps reduce partner motion when one of you moves.

Key benefits
- More room each: Each of you gets 75cm of width, which is 7.5cm more per person than the UK double, so elbows and knees meet far less often in the night.
- Length for taller sleepers: At 200cm (6ft 6in), the UK king is 10cm longer than the UK double, which means a partner over six foot is less likely to end up with feet over the end.
- Fewer disturbances on different schedules: The pocket springs are individually wrapped and move on their own, so an early riser climbing out should disturb the person still asleep a little less.
- Usable right to the edge: Edge-to-edge support means the outer part of the 150cm width stays usable, so neither of you drifts towards the middle to feel properly supported.
- Firm support for two back sleepers: The firm feel suits most back sleepers sharing a UK king, although a lighter side sleeper may find it slightly unyielding at the shoulders and hips.
This size suits you if...
You share the bed every night and have started to feel cramped in a UK double, or one of you is over six foot and the extra 10cm of length would make a real difference to how you lie.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m for a UK king. The UK double would suit you better, and we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the Sleepeezee Nova 1800 UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than the UK double. That sounds modest on paper, but it is usually enough to stop you rolling into each other. If you both sprawl, the UK super king gives 90cm each.
Will a UK king Nova 1800 suit a partner over six foot?
It is the better choice for them. The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. A partner over six foot is less likely to have their feet at the very end, and they won't feel pushed to sleep diagonally.
What size bedroom do I need for a Sleepeezee Nova 1800 king size?
We suggest at least 2.7m x 2.9m. Measure carefully in a new build master bedroom, because fitted wardrobes and a radiator can take more floor than the plans suggest. Check the stairs and landing too, then compare the retailers listed on this page.
Should I choose the Nova 1800 in a UK king or a UK super king?
The UK super king is 30cm wider at the same length and gives 90cm each, so the UK king gives you 15cm less each. The UK super king needs more room, though: we suggest at least 3m x 2.9m. If your bedroom falls short of that, the UK king is the realistic upgrade.
Will I feel my partner move on the king size Nova 1800?
Less than on a narrower bed. The individually wrapped pocket springs respond separately, and the 75cm each of a UK king puts a little more distance between you. That helps if one of you gets up hours before the other, although on any shared mattress you may still notice some movement.
