Layer Details
Knitted cover
A soft knitted top that adds cosiness and warmth while allowing enhanced airflow. In practice, that means a gentler first touch without trapping quite as much heat as some foam mattress covers.
Memory Foam
A 3cm comfort layer that adapts to the contours of your body and moulds to your shape, which means pressure points like hips and shoulders get some cushioning. It's a fairly slim layer, so the firm base makes itself felt through it.
Reflex Foam
A 17cm supportive base that is durable and resilient, holding its shape over an extended period. This is where the firm feel comes from, and it should keep the mattress performing consistently for longer.

Key benefits
- Real space for two: At 75cm each for two people sharing, you can both change position without negotiating for territory.
- Less partner disturbance: The all-foam build absorbs movement well, which means one of you getting up early is less likely to wake the other.
- Extra length for taller sleepers: At 200cm long, it's 10cm longer than a UK double, so feet stay on the mattress rather than hanging off it.
- Firm support across the full width: The 17cm reflex foam base holds its shape edge to edge, so the wider surface stays consistent rather than dipping where you each sleep.
- An affordable route to a king: Sizing up usually stings; this firm foam build keeps a king upgrade within reach, and the prices shown here update as retailers change them.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you sleeps on your back or front and wants firm support. It also makes sense if one partner is tall, since the 200cm length is a genuine relief for anyone approaching six foot, or if you're on different schedules and want movement absorbed rather than transmitted.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m, which leaves a king feeling squeezed once wardrobes are in. We'd recommend the UK double instead, where we suggest at least 2.6m x 2.8m.

FAQ's
Is a UK king Bodyshape Ortho mattress big enough for a couple?
Comfortably, for most. You get 75cm each for two people sharing, which is a noticeable step up from a double, and the firm foam build stays supportive across the full width. If one of you is very restless or you like a lot of spread, the UK super king is 30cm wider still.
Will the Bodyshape Ortho king fit in a new build master bedroom?
Often, but measure first. New build masters can be smaller than they look once fitted wardrobes go in. We suggest at least 2.7m x 2.9m for the 150 x 200cm UK king, with room to walk both sides. If yours is tighter, the UK double needs at least 2.6m x 2.8m.
Is the UK king Bodyshape Ortho long enough for someone over six foot?
At 200cm, it's 10cm longer than a UK double, which is usually the difference between feet hanging off the end and not. If one of you is tall, that extra length is often the real reason to size up, with the added width a welcome bonus.
Does this mattress reduce partner disturbance in a king size?
Foam mattresses transfer less movement than sprung ones, and the firm reflex base here keeps the surface stable. Combined with 75cm each for two people sharing, a partner getting up hours before you is far less likely to wake you than on a smaller sprung bed.
How does the king compare with the super king in this mattress?
The UK king is 30cm narrower than the UK super king, and the two are the same length. The super king suits couples who want maximum space, or share with children or a dog, but it needs a bigger room: we suggest at least 3m x 2.9m for it.
