Layer Details
- Cover. A Cooler Extreme fabric cover with cool-touch properties, which means the surface feels noticeably cooler when you first lie down. It works by dispersing heat away from your body through the night.
- StayCool gel. Pressure-sensitive StayCool gel that creates a supportive, edge to edge floating sensation. It also reduces heat build-up, so warm sleepers should feel a genuine difference.
- Pocket springs and Softech springs. Pocketed and Softech springs deliver body-cushioning comfort, with 1,800 springs in the king size. Each spring moves independently, which means support that follows your shape rather than pushing back as one unit.
- Superbond foam. Superbond foam forms part of the filling system, adding a stable comfort layer beneath the springs and gel.

- More room for each of you: The UK king gives you 7.5cm more each than a UK double, which means less shuffling towards the edge and fewer accidental elbows in the small hours.
- Length for a taller partner: At 6ft 6in long, the UK king adds 10cm over a UK double, so someone over six foot can stretch out without their feet meeting the footboard.
- Calmer mornings on different schedules: Independent pocketed springs plus the extra width help keep an early alarm and a quiet exit on one side of the bed.
- 1,800 springs in this size: Sleepeezee quotes 1,800 springs for the king size specifically, and says other sizes may differ, so that figure applies to exactly this mattress.
- Cooling for two bodies: Two people under one duvet generate more warmth, and the StayCool gel beneath the cool-touch cover is there to reduce that heat build-up.
- Fits where a super king won't: We suggest at least 2.7m x 2.9m for the UK king, against 3m x 2.9m for the UK super king, which helps in a tighter master bedroom.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is over six foot and keeps running out of length, or you get up at different times and want the early riser's movements to stay on their own side.
Consider another size if...
You sleep alone, or your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the Sleepeezee Cooler Extreme 1800 king size long enough for someone 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 is often the bigger change than the width, because it gives room to stretch out without feet hanging off the end.
How much space does each person get on a king Sleepeezee Cooler Extreme 1800?
Two people sharing get 75cm each on the UK king. That is 7.5cm more each than on a UK double, a small figure on paper that you tend to notice most when one of you sleeps spread out.
Will I feel my partner getting up on the Sleepeezee Cooler Extreme 1800 in a UK king?
Less than on a narrower bed, most likely. The pocketed springs move independently rather than as one unit, and the UK king puts 75cm between you each, so an early riser climbing out is less likely to jolt the other person awake. Some movement still travels, just a little.
Should we choose the UK king or UK super king Sleepeezee Cooler Extreme 1800?
The UK super king gives 15cm more each, but we suggest at least 3m x 2.9m for it. The UK king needs at least 2.7m x 2.9m and is the same length. If your room is tight once wardrobes are in, the UK king is the sensible choice.
Will a Sleepeezee Cooler Extreme 1800 king fit in a new build master bedroom?
Measure after the wardrobes and bedside tables are in, because new build rooms often shrink once furnished. We suggest at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m comfortable. At 150 x 200cm and 30cm deep, it also sits fairly tall on its base.
