Layer Details
Cool-Touch Surface
A sleeping surface that feels cool to the touch, designed to reduce body temperature. You'll notice it most when first getting into bed.
Staycool™ Gel
Pressure sensitive gel that responds immediately to your body shape, which means contouring without losing the firm feel. It also helps regulate body temperature through the night.
White fibre filling
This layer cushions spring movement and reduces allergens. A sensible inclusion if you're prone to allergies.
Pocket spring core
The spring system at the heart of the mattress, providing the underlying support.

Key benefits
- More room each: At 75cm each for two sharing, the UK king gives you 7.5cm more each than the UK double, which means fewer elbows and knees meeting in the night.
- Length for a taller partner: The UK king is 10cm longer than the UK double, so someone approaching 6ft can lie straight without their feet reaching the end.
- Calmer mornings on different schedules: If one of you rises hours earlier, the wider surface plus a fibre layer that cushions spring movement should make the early start a little less noticeable to whoever stays in bed.
- Cooling for two: Two people under one duvet make more warmth, so the cool-touch surface and Staycool gel suit couples where one or both of you tend to wake up hot.
- Space without super king demands: We suggest at least 2.7m x 2.9m for the UK king, compared with at least 3m x 2.9m for the UK super king.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, or one of you is close to six foot and wants the extra length. It also suits you if your working hours differ and you'd like a little more distance from a partner who gets up early.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Cool Refresh 1600 king size good for couples?
For most couples, yes. The UK king gives 75cm each for two sharing, and the cooling surface helps when two bodies warm the bed. The one flaw is the feel: Sleepeezee describes it as extra firm, so a lighter partner who sleeps on their side may find the shoulder and hip area a little unyielding.
Is the Cool Refresh 1600 in a UK king long enough for someone over 6ft?
The UK king is 200cm long (6ft 6in), which is 10cm longer than the UK double. That extra length is often the real reason tall sleepers upgrade. The UK super king is the same length, so sizing up adds width but no extra length.
Should we get the Sleepeezee Cool Refresh 1600 in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king and gives 15cm less each. The UK super king gives 90cm each, but we suggest at least 3m x 2.9m for it, against 2.7m x 2.9m for the UK king. If floor space is tight, the UK king is the more practical choice.
Will a UK king Cool Refresh 1600 fit in a new build master bedroom?
Often it will, but measure after the fitted wardrobes are in, because new build bedrooms lose a surprising amount of floor to them. We suggest at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m feeling comfortable once you add bedside tables.
