Layer Details
- Advance e-Fibre™. These comfort layers have a breathable cell structure that improves air flow and helps moisture evaporate, which means a cooler, drier sleep surface through the night. It's a fibre-based alternative to foam, so hot sleepers tend to get on with it.
- Open coil spring core. A deep sprung core, with 325 springs in the king size, distributes support evenly across the mattress. Open coil gives a gently springy, traditional feel rather than the contouring you'd get from pocket springs.

- Real space for two: At 75cm each for two people sharing, partners on different schedules can settle or leave without a tangle of elbows in the middle.
- Extra length for taller sleepers: The 200cm length is 10cm more than the UK double, which means anyone approaching six foot stops finding their feet at the edge.
- 325 springs across the king: The open coil core in the UK king uses 325 springs, spreading two sleepers' weight evenly rather than dipping where the heavier partner lies.
- Breathable across a bigger surface: Two bodies generate more heat than one, and the e-Fibre layers let air move through the mattress, so a shared bed stays cooler and drier.
- Rolled delivery, easier stairs: A king is an awkward size to move flat, so arriving rolled makes getting it to an upstairs bedroom genuinely manageable.
This size suits you if...
You're a couple who has outgrown a double and wants a proper stretch of space each, one of you is tall enough that a standard 190cm mattress feels short, or you're pregnant or recovering from surgery and need room to prop pillows and shift position without crowding your partner.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you mostly sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

How many springs does the Jay-Be Ryze Comfort have in a UK king?
The UK king uses 325 open coil springs in its sprung core. That count spreads support evenly across the full 150cm width, so two sleepers of different weights both get a consistent surface. Open coil gives a gently springy, traditional feel rather than the close contouring of pocket springs, and this size gives it the most room to do that.
Is the Jay-Be Ryze Comfort UK king good for couples?
The width certainly helps: 75cm each for two people sharing means less accidental contact through the night. One caveat: open coil springs transfer more movement than pocket springs, so if your partner is restless or gets up hours before you, you'll feel it more than the extra space alone suggests. Couples who sleep soundly will be fine.
What size room do I need for the Jay-Be Ryze Comfort in a UK king?
We suggest a room of at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with the furniture in place. If the numbers don't work, the UK double needs at least 2.6m x 2.8m.
Is the UK king Jay-Be Ryze Comfort long enough for tall sleepers?
At 200cm, or 5ft x 6ft 6in, it's 10cm longer than the UK double, and that length is often the real reason taller couples upgrade rather than the width. If one of you is over six foot, this is the size where feet stop hanging off the end. The 21cm depth also suits standard king fitted sheets.
