Key benefits
- More room for each of you: At 75cm per person you each gain 7.5cm over the UK double, which means fewer knocked elbows when one of you rolls over in the night.
- Length for a taller partner: At 200cm (6ft 6in) the mattress is 10cm longer than the UK double, so a partner over six foot can stretch out without their feet reaching the edge.
- A little distance on different schedules: If one of you is up hours before the other, the extra width keeps you slightly further apart, and Silentnight says its Mirapocket springs adapt to each body.
- Airflow for two warm bodies: Sharing a bed builds up heat, and Silentnight uses airy fibres intended to help air move through the surface, which should suit couples who tend to wake up warm.
- Space without super king demands: We suggest a room of at least 2.7m x 2.9m for this size, 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 have started to feel cramped on a double, one of you is near or over six foot and keeps hitting the end, or you keep different hours and want a bit more space between you.
Consider another size if...
Your bedroom measures under 2.7m x 2.9m once the wardrobes are in. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's
Is the Silentnight Breatheasy 1000 UK king long enough for someone over six foot?
It is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner over six foot, that extra length often makes more difference than the extra width, because it leaves room for a pillow at the top without your feet pressing against the end.
How much space does each person get on a UK king Breatheasy 1000?
Two sharers get 75cm each, which is 7.5cm more per person than the UK double's 67.5cm. That doesn't sound like much on paper. In bed, though, it's the gap that stops a restless partner's shoulder ending up in your space, and it gives you a little more room to shift position with extra pillows.
What size bedroom do I need for a king size Breatheasy 1000?
We suggest at least 2.7m x 2.9m, and around 3.2m x 3.2m feels comfortable. New build master bedrooms can look generous when empty and then shrink once fitted wardrobes go in, so measure with the doors open, then compare the retailers listed on this page.
Should we get the Breatheasy 1000 in a UK king or UK super king?
The UK super king gives 90cm each, 15cm more per person than the UK king, and both sizes are 200cm long. If length is your main reason to upgrade, the UK king already gives you that. The UK super king also needs more floor space: we suggest at least 3m x 2.9m.
What sheets and duvet fit a 36cm deep king mattress?
Look for king fitted sheets with deep pockets, because at 36cm this mattress is thicker than many and shallow sheets can ping off the corners. Check the pocket depth on the packet before you buy. A 230 x 220cm king duvet fits the 150 x 200cm surface.
