Layer Details
- Bamboo cover. An ultra-soft knitted bamboo cover wicks away moisture, which means less clamminess on warm nights. It also has a naturally antibacterial finish to help prevent odours forming.
- Pillow top. A cloud-like pillow top adds a plush, indulgent surface feel over the firm core. It includes a layer of cooling gel for soothing relief as you sleep.
- Staycool gel. Dual layers of Staycool gel regulate your temperature through the night. They also give pressure-sensitive support, adapting to where your body pushes in most.
- Pocket springs. 2,400 pocket springs in the king size move independently to cushion your body, which means less disturbance when a partner shifts. Highly adaptive nano pocket springs add a finer layer of support.
- Side support border. An enhanced side support border creates a durable edge around the mattress. This helps prevent dipping or sagging where you sit or sleep near the side.

- Room to yourselves: You each get 75cm of width, which means 7.5cm more each than the UK double, enough to stop elbows meeting every time one of you rolls over.
- 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 their feet hanging off the end.
- Calmer nights on different schedules: If one of you is up hours before the other, the 2,400 independently moving springs in the king size help keep that early exit from waking the sleeper left behind.
- A firm edge across a wider bed: The reinforced side border runs the full 200cm length, so you can sit on either side to get in or out without the edge dipping under you.
- Cushioning where two bodies press in: The pillow top softens a firm core on shoulders and hips, although lightweight side sleepers may still find the Witham a little too firm.
- Space without a super king's footprint: We suggest at least 2.7m x 2.9m for the UK king, while the UK super king needs at least 3m x 2.9m.
This size suits you if...
You share the bed every night and have started to feel cramped on a double, one of you is over six foot and keeps running out of length, or your hours differ and you want the early riser's movements to reach the other person less.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

Is the Sleepeezee Witham UK king big enough for two people?
Yes, for most couples. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. If you both sprawl, or a dog regularly joins you, the UK super king gives 90cm each, although it needs a larger room.
Is the Sleepeezee Witham king long enough if you're over 6ft?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner over six foot, that extra length can make more difference than the extra width. The UK super king is the same length, so sizing up beyond the UK king adds width only.
Will I feel my partner moving on a Sleepeezee Witham king size?
Less than on many beds. The king size uses 2,400 pocket springs that move independently, which means a partner turning over or getting up early disturbs the springs near them rather than the whole surface. The 75cm each also puts a little more distance between you than a UK double would.
Sleepeezee Witham king or super king: which should couples choose?
The UK king gives you 75cm each, while the UK super king gives 90cm each, so the UK king offers 15cm less each. Both are 200cm long. We suggest at least 2.7m x 2.9m for the UK king and 3m x 2.9m for the UK super king, so check your bedroom first.
What size bedroom do I need for a Sleepeezee Witham UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms often shrink quickly once wardrobes go in, so measure after furniture is placed. You need space on both sides to get in and out, especially if one of you is recovering from an injury.
