Layer Details
Knitted cover
A soft knitted cover that adds a cosy, warm finish. It's designed to aid airflow and breathability, which means a slightly cooler sleep surface.
Wool and cashmere blend
A plush layer of natural wool and cashmere with breathable, moisture-wicking properties. In practice, this helps regulate your body temperature through the night.
Soft white fibres
A layer of soft white fibres that rounds out the feel with extra comfort. It also adds breathability and helps the mattress last.
Pocket springs
2000 traditional pocket springs, each encased in its own fabric pocket so it can move independently. This means the support adapts to your shape rather than pushing back as one unit.

Key benefits
- Room to stop elbows meeting: At 75cm each for two sharing, the UK king gives you 7.5cm more each than the UK double, a little extra space that makes a difference every night.
- Length for a tall partner: It's 10cm longer than the UK double, which means a tall partner can lie straight on firm support instead of sleeping with their feet at the very end.
- Kinder to different body clocks: If one of you is up hours before the other, independent springs plus a wider surface mean their getting up is less likely to wake the person still asleep.
- Measure before you commit: We suggest at least 2.7m x 2.9m for a UK king, so check a new build master bedroom after the wardrobes are fitted, when rooms often feel smaller.
- Easy to match an older frame: In old money the UK king is 5ft x 6ft 6in, helpful if your bed frame or headboard was sold in feet and inches.
This size suits you if...
You share the bed every night and have started to feel cramped on a UK double, or one of you is tall enough to want more length. It also fits if your partner gets up long before you and you'd like to feel less of it when they do.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m. In that case, we'd recommend the UK double instead, and we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Is the Sleepeezee Ultimate Ortho 2000 UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two sharing, compared with 67.5cm each on the UK double, so you gain 7.5cm of personal space. That's enough to stop regular contact for many couples, although broad-shouldered sleepers who like to spread out may still want more.
Will I feel my partner move on a king size Sleepeezee Ultimate Ortho 2000?
Less than on a smaller shared size, most likely. The 2000 springs sit in separate pockets and move independently, so movement stays closer to where it happens. On a UK king you also lie 7.5cm further apart each than on a UK double, which gives that movement a little further to travel.
Is the Sleepeezee Ultimate Ortho 2000 in a UK king long enough for a tall person?
It's 200cm long, which is 10cm longer than a UK double and the same length as a UK super king. If length is your main reason for upgrading, the UK king gives you the full extra length without the extra width of the UK super king.
Sleepeezee Ultimate Ortho 2000 king or super king: which should I choose?
The UK super king gives 90cm each for two sharing, so the UK king gives 15cm less each. It needs less space, though: we suggest at least 2.7m x 2.9m for the UK king and at least 3m x 2.9m for the UK super king. If your room is tighter, the UK king is the sensible choice.
Is the Sleepeezee Ultimate Ortho 2000 king size hard to move and rotate?
Across verified owner reviews, some owners find this mattress heavy and awkward to move, and a UK king is a large mattress to handle. It's single-sided, so it needs rotating rather than flipping. Sleepeezee doesn't list a weight for the UK king here, so check the brand's own guidance and plan on two people to rotate it.
