Key benefits

Key Benefits of the Hypnos Cotton Deluxe Bedstead Medium Firm King Size Mattress

  • 75cm each for two sharers: Two people get 75cm of width apiece, which means you can spread out without negotiating for territory in the middle of the night.
  • Pocket springs plus space equals less disturbance: Each spring moves independently, so a partner getting up early on a different schedule is far less likely to wake you across the wider 150cm surface.
  • Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping diagonally or dangling their feet.
  • Room for the dog too: If a pet on the bed is part of your routine, the 15cm of extra width over a UK double is the difference between comfort and compromise.
  • Natural fillings across a bigger surface: The premium natural fillings breathe better than synthetic foams, useful when two bodies are sharing one mattress every night.

Who should buy the Hypnos Cotton Deluxe Bedstead Medium Firm King Size Mattress?

This size suits you if...

You share the bed every night and a double leaves you brushing elbows, or one of you is close to six foot and needs the 200cm length. It also fits couples on different schedules, since the pocket springs and 75cm each of width mean an early riser can slip out with less chance of waking the other. Allow at least 2.7m x 2.9m of bedroom space.

Consider another size if...

Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. In either case we'd recommend the UK double instead, which needs a slightly smaller room at 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

How much space do two people get on the Hypnos Cotton Deluxe Bedstead UK king?

You get 75cm each for two people sharing, across a total width of 150cm. Combined with the pocket springs, which compress individually rather than tilting the whole surface, that spacing means one person shifting or getting up disturbs the other noticeably less than on a narrower mattress.

Is the UK king Hypnos Cotton Deluxe Bedstead long enough for tall sleepers?

At 200cm, or 5ft x 6ft 6in in imperial, the UK king is 10cm longer than the UK single, UK small double and UK double. For anyone approaching six foot, that extra length is often the real upgrade, since it stops feet hanging off the end or a permanent diagonal sleeping position.

What room size does the Hypnos Cotton Deluxe Bedstead UK king need?

We suggest at least 2.7m x 2.9m. New build master bedrooms can feel smaller than the floor plan suggests once wardrobes and drawers go in, so measure with furniture in place. If the space is tight, the UK double needs slightly less at 2.6m x 2.8m and still shares this mattress's medium firm pocket spring feel.

Should I get the king or super king in this Hypnos mattress?

The UK king is 30cm narrower than the UK super king, and both are the same 200cm length. If you share with children or a dog most nights and have a room of at least 3m x 2.9m, the UK super king is worth considering. For most couples, the UK king balances space against room demands.
