Key benefits

Key Benefits of the Hypnos Bryher King Size Mattress

  • More room between you: At 75cm each, you get 7.5cm more personal space than on a UK double, so an early alarm or a restless turn happens a little further from your partner.
  • Extra length for taller sleepers: The UK king is 200cm long, or 6ft 6in, which means feet stay on the mattress for a partner who regularly finds a UK double too short.
  • Edges you can use: Four hand-stitched rows of edge support help the outer strip of this UK king stay usable, which matters when you're perching on the side to get up carefully.
  • Wear spread across a bigger surface: The Bryher is turnable, so rotating your UK king head to toe stops the dips from forming in the same two spots where you each lie.
  • Space without a super king room: You gain real width over a UK double, while our suggested minimum stays at 2.7m x 2.9m rather than the larger floor a UK super king needs.

Who should buy the Hypnos Bryher King Size Mattress?

This size suits you if...

You share the bed every night and one of you gets up or turns in well before the other, or a partner near six foot keeps meeting the end of a UK double, and your bedroom comfortably clears our suggested 2.7m x 2.9m.

Consider another size if...

Your bedroom falls short of 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, and suggest at least 2.6m x 2.8m for it.

FAQ's

Frequently Asked Questions About the UK King

Is the Hypnos Bryher UK king big enough for two people?

For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than a UK double. If you sprawl, or share with a dog that claims the middle, you may still feel a little short of room, and the UK super king gives 15cm more each.

What size bedroom do I need for a Hypnos Bryher UK king?

We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. Measure after wardrobes and bedside tables are placed, because a new build master bedroom often looks bigger empty than it does furnished.

Is a UK king Hypnos Bryher long enough if you're over 6ft?

The UK king is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. For a partner over six foot, that extra length is often the more noticeable upgrade, since a UK double's 190cm can leave feet near the edge.

Should I get the Hypnos Bryher in a UK king or UK super king?

Both are 200cm long, so the choice comes down to width and room. The UK super king gives 90cm each, 15cm more than the UK king, but we suggest at least 3m x 2.9m for it. If your room is under that, the UK king makes more sense.

What bedding fits a Hypnos Bryher in UK king size?

Standard UK king sheets fit, and a 230 x 220cm king duvet covers two people properly. The Bryher is 31cm deep, so choose a fitted sheet with deep enough corners to tuck under that depth.
