Key benefits
- More room each than a double: You get 75cm each, which is 7.5cm more per person than the UK double, enough to stop elbows meeting when one of you turns over.
- Length for taller sleepers: At 200cm long, the UK king adds 10cm over the UK double, so a partner over six foot is less likely to end up with feet hanging off the end.
- Less disturbance on different schedules: Pocket springs move independently, which means the person still asleep should feel less of an early riser getting up from the far side of a UK king.
- Space to prop and shift: During pregnancy or recovery, the UK king leaves room for support pillows and changes of position without pushing your partner towards the edge.
- Seasonal sides at full size: Flipping between the summer and winter sides takes two people at this size, but you only do it a couple of times a year rather than changing bedding constantly.
This size suits you if...
You share the bed every night and have started to feel cramped in a double, one of you is tall and wants the extra length, or you keep waking each other on different schedules and want a bit more distance between you.
Consider another size if...
Your bedroom measures under our suggested 2.7m x 2.9m for a UK king. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Flaxby Silkstone UK king big enough for two adults?
For most couples, yes. The UK king gives 75cm each, which is 7.5cm more per person than the UK double. If one of you sprawls, or a dog regularly joins you, you may still find it a little snug, and the UK super king gives 90cm each instead.
What size room do I need for a UK king Flaxby Silkstone?
We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. A new build master bedroom can feel smaller than its plans once wardrobes are fitted, so measure the space that's actually left before ordering.
How much longer is a UK king than a UK double?
The UK king is 10cm longer than the UK double, at 200cm. That length is often the real reason to move up if one partner is around six foot, because width alone won't stop their feet reaching the end.
What bedding fits the Flaxby Silkstone in a UK king?
Standard UK king sheets and a 230 x 220cm king duvet fit the 150 x 200cm surface. At 39cm deep, though, check that any fitted sheet has a deep enough pocket to tuck under properly.
Should we choose the UK king or the UK super king in this mattress?
The UK king is 30cm narrower than the UK super king but the same length, giving 15cm less each. If your room fits at least 3m x 2.9m and you disturb each other badly, the UK super king is the better choice. Otherwise, the UK king suits most couples well.
