Key benefits
- More room each: You each get 75cm instead of the 67.5cm a UK double allows, which means less elbow contact when one of you rolls over in the night.
- Length for a tall partner: At 200cm long, the UK king adds 10cm over a UK double, so a partner over six foot is less likely to sleep with their feet over the edge.
- A little distance on different schedules: If one of you is up hours before the other, the extra width gives the person getting up a bit more space to leave without disturbing the sleeper.
- A cooler surface for two: The CoolEase cover is designed to draw heat away, which helps on a bed where two bodies give off warmth through the night.
- Fits rooms a UK super king won't: We suggest 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 a UK double and keep ending up on each other's side, or one of you is tall enough that 190cm feels short, and your bedroom still clears our suggested 2.7m x 2.9m once the wardrobes are in.
Consider another size if...
Your bedroom falls short of 2.7m x 2.9m once the furniture is in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Silentnight Reflex 2200 in a UK king big enough for two people?
For most couples, yes. You each get 75cm, which leaves room for a pregnancy pillow or a change of position without crowding your partner. If a dog sleeps on the bed every night, the UK super king gives 90cm each, so it may suit you better.
Will a UK king Silentnight Reflex 2200 fit in a new build master bedroom?
New build master bedrooms often feel smaller once fitted wardrobes are in, so measure the clear floor space rather than the walls. We suggest at least 2.7m x 2.9m. Measure the stairs and landing too, then compare the retailers listed on this page.
Is a UK king long enough for someone over six foot?
The UK king is 200cm long, or 6ft 6in. That is 10cm more than a UK double, which gives a tall sleeper room to stretch out with a pillow at the top. If length is the main reason you are upgrading, the UK super king is the same length and only adds width.
UK king or UK super king Silentnight Reflex 2200: which should we choose?
The UK king is 30cm narrower than the UK super king and the same length. It gives you 75cm each against 90cm. Choose the UK super king if you have at least 3m x 2.9m of space and want the widest gap between you. Otherwise the UK king gives couples plenty of space.
What bedding fits a UK king Silentnight Reflex 2200?
Standard UK king sheets fit, and a 230 x 220cm king duvet covers two people comfortably. The mattress is 33cm deep with a pillow top, so look for deep-pocket fitted sheets that will tuck under properly.
