Layer Details
- Damask Cover. A breathable Belgian damask fabric cover. It lets air move through the surface, which means less heat building up around you overnight.
- Comfort Layer. A generous polyester and cotton blend layer that cushions your body. It softens the surface slightly without compromising the firm feel underneath.
- Soft White Fibres. Fibre fillings made from 100% polyester. These recover their shape well, which means the comfort layers should resist flattening over time.
- Cotton. A natural filling that helps regulate body temperature. It also adds a touch of extra support and comfort.
- Pocket Springs. Up to 1600 pocket springs that work independently, contouring to your body as you move. That means targeted pressure relief where you need it, and less disturbance from a partner shifting about.
- High-density Support Layers. Dense support layers on both sides of this double-sided mattress. They add further pressure relief and let you flip the mattress to spread the wear.

- Room to settle on your own side: You each get 75cm of width, which is 7.5cm more per person than the UK double, so elbows and knees meet far less often through the night.
- Less wake-up from an early riser: The pocket springs move independently, which means a partner leaving hours before you is less likely to jolt your side of the mattress as they get up.
- Length for taller sleepers: At 200cm, or 6ft 6in, a UK king is 10cm longer than a UK double, which often matters more than width to a partner over six foot.
- Firmness across the whole surface: Sleepeezee describes the mattress as extra firm, and on a UK king that consistent feel runs edge to edge, so neither of you ends up on a softer patch.
- Space without super king demands: We suggest a room of at least 2.7m x 2.9m, a little less than the 3m x 2.9m we'd allow for the UK super king.
This size suits you if...
You share a bed every night and keep brushing against each other on a UK double, or one of you rises much earlier than the other. It also suits you if a partner over six foot needs the extra length, and you both prefer a bed that feels properly solid.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m, or you sleep alone. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

Is the Sleepeezee Ortho Firm 1600 UK king good for couples who disturb each other?
It should help. The pocket springs work independently, so movement stays closer to the person making it, and a UK king gives you 75cm each. If one of you gets up well before the other, that mix of spring design and extra width means fewer knocks crossing the bed.
Is a UK king Ortho Firm 1600 long enough for someone over 6ft?
A UK king is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. For a partner over six foot, that length is often the real reason to upgrade. The UK super king is the same length, so sizing up beyond a UK king only adds width.
Should I choose the Ortho Firm 1600 in a UK king or UK super king?
The UK king gives 75cm each, 15cm less per person than the UK super king. If you sleep comfortably without touching and your room is under the 3m x 2.9m we suggest for a UK super king, the UK king is the better fit. A dog that sleeps on the bed can tip the balance towards more width.
Is a king size Sleepeezee Ortho Firm 1600 hard to flip?
The mattress is double-sided and meant to be flipped, and a UK king is a large, 150cm-wide thing to turn over. Sleepeezee doesn't publish a weight for this size, so plan to do it with two people, and check the brand's own guidance on how often to flip.
Is it worth upgrading from a double to the Ortho Firm 1600 in a UK king?
If space is the problem, yes. You gain 7.5cm each and 10cm of length over a UK double, which you notice every night. Check the room first: we suggest at least 2.7m x 2.9m for a UK king. Compare the retailers listed on this page, as prices shown here update as retailers change them.
