Layer Details
Damask Cover
A breathable cover made from Belgian damask fabric. Breathability here means air can move through the surface, which helps the mattress feel less stuffy on warm nights.
Polyester and Wool Blend
A comfort layer blending polyester with wool, which is naturally temperature regulating. In practice that means it helps even out warmth rather than trapping heat against you.
Soft White Fibres
Fibre fillings made from 100% polyester, chosen for recovery and durability. They spring back into shape after use, which helps the surface resist dips over time.
1000 Pocket Springs
Up to 1000 springs, each pocketed so it works completely independently of the others. This gives targeted support and reduces the ripple you feel when a partner moves.

Key benefits
- More room each than a double: You each get 75cm of width, which is 7.5cm more per person than the UK double and enough to stop elbows meeting in the night.
- Less disturbance from a partner: Independent pocket springs combined with that extra width mean an early riser can get up without the bed rocking the other sleeper awake.
- Extra length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot is less likely to have feet over the edge.
- Firm support across a wider surface: The firm feel holds each of you level on your own half, rather than letting a heavier partner create a slope you roll towards.
- Fits more rooms than a super king: You get most of the space of a bigger bed, and we suggest at least 2.7m x 2.9m of room rather 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 keep waking when your partner moves, or one of you is over six foot and the UK double is simply too short. It also suits you if you both prefer a firm surface on your back or front and want more room each without giving the whole bedroom over to the bed.
Consider another size if...
Your room is smaller than our suggested 2.7m x 2.9m, perhaps once wardrobes are in. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Ortho Firm 1000 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. With the firm pocket springs, that extra width means you are less likely to feel your partner shifting. If you both like to sprawl, the UK super king gives 90cm each.
Is a king size Sleepeezee Ortho Firm 1000 long enough for someone over 6ft?
The UK king is 200cm long, which is 5ft x 6ft 6in in imperial, and 10cm longer than the UK double. That extra length is often the main reason taller sleepers move up to a UK king. The UK super king is the same length, so going bigger than a UK king only adds width.
Will I feel my partner getting up on the Ortho Firm 1000 king size?
Less than on a smaller bed. The springs are individually pocketed, so movement on one side travels less to the other, and the UK king puts 75cm of width between you. That helps when one of you leaves for work hours before the other. A little movement will still come through on any sprung mattress.
Should I get the Sleepeezee Ortho Firm 1000 in king or super king?
Choose the UK king if you want more room than a double but your bedroom is modest. We suggest at least 2.7m x 2.9m for the UK king. The UK super king is 30cm wider, giving 90cm each, but needs at least 3m x 2.9m by our guidance. Both are 200cm long.
What room size do I need for a Sleepeezee Ortho Firm 1000 UK king?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. That leaves space to walk around both sides and get in and out easily. Measure after wardrobes and drawers are in, because a new build bedroom can feel much smaller once it is furnished.
