Key Benefits of the Hypnos Cotton Origins 6 King Size Mattress

  • 75cm each for two sharing: Each of you gets 75cm of width, which means turning over without negotiating for space or waking the person next to you.
  • Pocket springs suit different schedules: Because each spring compresses independently, an early alarm on one side transmits far less movement to the other, useful when your mornings don't match.
  • 200cm length for taller sleepers: The UK king is 10cm longer than the UK double, so anyone approaching six foot gets their feet on the mattress rather than off the end.
  • Edge support across a wider bed: Triple Edge Protection springs firm up the perimeter, so the outer stretch of this 150cm width stays usable rather than feeling like a slope.
  • Hand-tufting across the full surface: Tufting anchors the fillings over the whole 150 x 200cm sleep area, which means less settling in the spots where each of you always lies.

Who should buy the Hypnos Cotton Origins 6 King Size Mattress?

This size suits you if...

You share the bed every night and a double has started to feel like a compromise, especially if one of you gets up hours before the other and the medium firm pocket springs need room to do their motion-isolating job. It also fits if either partner is tall, since the 200cm length takes the pressure off, or if a dog has quietly claimed a share of the mattress.

Consider another size if...

Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, which needs a room of at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Hypnos Cotton Origins 6 in a UK king big enough for two adults?

Comfortably, for most couples. At 150cm wide you get 75cm each, and the pocket sprung construction means each side responds to its own sleeper rather than the pair of you moving as one. If one of you sprawls or you regularly share with a child or pet, the UK super king adds another 30cm of width.

What room size do I need for a UK king Hypnos Cotton Origins 6?

We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves enough space to walk round both sides and open drawers. New build master bedrooms can be tighter than they first appear once fitted wardrobes go in, so measure the usable floor rather than the wall-to-wall figure.

Is the UK king long enough for someone over six foot?

It helps considerably. The UK king is 200cm long, 10cm more than the UK double, which is often the difference between heels on the mattress and heels hanging off it. Length, rather than width, is frequently the real reason taller sleepers upgrade, and the UK super king is the same length, so there's no gain in going bigger for height alone.

Should I choose the king or super king in this mattress?

The UK king suits most couples: real personal space without the room demands of a bigger bed. The UK super king is 30cm wider and needs a room of at least 3m x 2.9m, so it makes sense if your bedroom is generous, you sleep with a dog on the bed, or you both want space to spread out fully.

How much bigger is the UK king than the double for this mattress?

The UK king is 15cm wider and 10cm longer than the UK double. On a medium firm pocket sprung mattress like this, that extra width is felt as reduced partner disturbance: with more distance between you, less of each movement carries across. Bear in mind you'll need king sheets and a 230 x 220cm king duvet.
