Sewn-in pillow top
A sewn-in pillow top filled with British wool, cotton, kapok, Himalayan allo, Solotex and eOlus recycled fibres. It adds extra cushioning over the medium-rated mattress, so the surface feels softer.
ReActivePro pocket spring core
ReActivePro pocket springs with six active turns, with Triple Edge Protection at the edges. The springs give the support underneath, and the protected edges help the sides hold up when you sit on them.

Key benefits
- A little more room each: At 150 x 200cm, you each get 75cm, so a partner turning over at 3am is slightly further away than on a UK double.
- Length for taller sleepers: The UK king measures 6ft 6in long, 10cm longer than a UK double, which means a partner over six foot can stretch out without their feet meeting the edge.
- Space to prop and shift: If you're pregnant or recovering and need a wedge of pillows, the extra width leaves your partner their own side rather than a narrow strip.
- Edges you can use: Triple Edge Protection helps the sides hold up when you sit on them, which matters on a wider bed where you'll often get in and out from the edge.
- Fits more bedrooms than a super king: We suggest at least 2.7m x 2.9m for a UK king, against at least 3m x 2.9m for the UK super king.
This size suits you if...
You share the bed every night and have started to feel crowded on a UK double, one of you is over six foot and keeps running out of length, or you go to bed and get up at different times and want a little more distance between you.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Hypnos Pillowtop Select 1200 UK king big enough for two people?
For most couples, yes. A UK king gives you 75cm each, which is 7.5cm more each than a UK double. If one of you sleeps in a starfish shape or a dog joins you most nights, the UK super king's 90cm each may feel less crowded.
What size bedroom do I need for a UK king Hypnos Pillowtop Select 1200?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms often look roomy empty but shrink once fitted wardrobes and bedside tables on both sides go in, so measure with the furniture in place.
Is a UK king mattress long enough if you're over six foot?
It's 200cm, or 6ft 6in, which is 10cm longer than a UK double. For a partner over six foot, that extra length is often the real reason to upgrade, more so than the width. The UK super king is the same length, so sizing up beyond a UK king adds width only.
Hypnos Pillowtop Select 1200 king or super king for a couple?
The UK king gives 75cm each; the UK super king gives 90cm each, which is 15cm more per person. Both are 200cm long. If your room clears our suggested 3m x 2.9m and you disturb each other a lot, the super king suits you better. Otherwise, the UK king is a sensible middle ground.
What bedding fits a Hypnos Pillowtop Select 1200 king size?
King sheets and a 230 x 220cm king duvet fit. The mattress is 29cm deep with a pillow top, so choose fitted sheets with deep enough pockets to tuck well under the corners rather than standard shallow ones.
