Layer Details
- Cover. A graphite cool cover with graphene, which means heat is drawn away from your body rather than trapped at the surface. Hot sleepers should notice the difference most.
- Gel layer. StaycoolTM Gel provides body-sensitive pressure relief while keeping the sleep surface cool. It cushions shoulders and hips without the warmth some foams build up.
- Support layer. A high-density support layer sits beneath the gel, adding structure. This is where much of the firm, supportive feel comes from.
- Springs. Pocket springs at the base move independently, so your partner's tossing is less likely to disturb you. The king size uses 1,000 springs; other sizes aren't detailed.
Layer details from furniturevillage.co.uk product page, September 2026.
- More room for each of you: The UK king gives you 7.5cm more each than a UK double, which means fewer elbows and less edging towards the side just to find some space.
- Length for a taller partner: At 200cm, the UK king is 10cm longer than a UK double, so someone over six foot can stretch out without their feet reaching the end.
- Less disturbance on mismatched schedules: The UK king is listed with 1,000 pocket springs that move independently, which means one partner getting up before dawn is less likely to wake the other.
- Cooler with two in the bed: Two people generate more warmth, and the graphene cover with a gel layer beneath is designed to draw heat away, which helps couples who run warm.
- Asks less of your room than a UK super king: We suggest at least 2.7m x 2.9m for the UK king, compared with 3m x 2.9m for the UK super king.
This size suits you if...
You share with a partner whose alarm goes off hours before yours and you both prefer a firm surface, or one of you is over six foot and the 190cm length of a UK double has started to feel cramped.
Consider another size if...
Your bedroom is a new build master that shrinks below our suggested 2.7m x 2.9m once wardrobes go in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Will my partner's movement wake me on a SmartTemp Ortho UK king?
It should be less likely than on a smaller bed. The UK king is listed with 1,000 independent pocket springs, and you each get 75cm of width, so there is more distance between you when one person turns over or gets up early. A firm surface also tends to transmit less of that sinking-in movement.
Is the SmartTemp Ortho UK king long enough for someone over 6ft?
The UK king measures 200cm, or 6ft 6in, which is 10cm longer than a UK double. That extra length is often the real reason taller sleepers upgrade. The UK super king is the same length, so sizing up beyond the UK king adds width only.
SmartTemp Ortho king or super king: which is better for couples?
The UK super king gives 90cm each, while the UK king gives 15cm less each at 75cm. Both are 200cm long. If your room reaches our suggested 3m x 2.9m and you want maximum personal space, the UK super king makes sense. Otherwise the UK king needs less floor, at 2.7m x 2.9m.
Is it worth upgrading from a double to a UK king SmartTemp Ortho?
For most couples, yes. The UK king gives 7.5cm more each than a UK double and adds 10cm of length. Yes, the UK king needs a larger room, but the gain is felt nightly, particularly if you keep different hours or one of you is tall.
Will a UK king SmartTemp Ortho fit in a new build master bedroom?
Measure after the fitted wardrobes are accounted for, because new build rooms often look bigger empty. We suggest at least 2.7m x 2.9m for the UK king. If you fall short, the UK double needs at least 2.6m x 2.8m.
