Layer Details
Cover
A knitted fabric cover, which means a soft touch surface against your sheets.
Advanced e-Fibre®
Jay-Be's award-winning Advanced e-Fibre® sits just below the cover for luxury comfort. It's also breathable, so heat can escape rather than build up around you.
Memory e-Fibre®
A fibre alternative to memory foam, giving quick response pressure relief. You get cushioning at the shoulders and hips without the slow sink of traditional foam.
Rebound e-Fibre®
Rebound e-Fibre® provides contour support, which means it follows your shape while pushing back enough to keep you from bottoming out.
Micro e-Pocket™ springs
A layer of small pocket springs that move independently for adaptable support. They respond to each part of your body separately, useful if you and a partner are different weights.
e-Spring™ core
The e-Spring™ core forms the base of the mattress, providing the main structural support beneath the comfort layers.

Key benefits
- Real space for two: At 75cm each for two people sharing, you both get genuine room to stretch on the soft e-Fibre® surface without meeting in the middle.
- Less partner disturbance: The Micro e-Pocket™ springs move independently, so when one of you slips out early the other feels far less of it across the wider 150cm surface.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, which means anyone approaching 6ft gets their feet on the mattress rather than off the end.
- Cooler sharing: Two bodies raise the temperature of any bed, but the breathable fibre layers and the extra width of a UK king give heat more room to escape.
- An eco upgrade: Sizing up usually means more foam heading to landfill eventually; this foam-free build is 100% recyclable, so the bigger mattress carries no extra environmental guilt.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially on a soft mattress where you both sink in a little. Or one of you is on a different schedule and keeps waking the other, and you want width plus independent springs working together. Or someone in the bed is approaching 6ft and needs the 200cm length more than anything else.
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. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still suits lighter solo sleepers well.

FAQ's
Is the Jay-Be Benchmark S7 in a UK king big enough for two adults?
Yes, comfortably for most couples. The UK king gives 75cm each for two people sharing, and because this is a soft mattress you'll appreciate the space: cushioned surfaces encourage you to settle in rather than perch. The Micro e-Pocket™ springs also support each of you separately, useful if you're different weights.
What room size do I need for the UK king Jay-Be Benchmark S7?
We suggest allowing at least 2.7m x 2.9m so you can walk round the bed and open wardrobes without shuffling sideways. New build master bedrooms can be tighter than they look once fitted furniture goes in, so measure the usable floor, not the room on the plan, before committing to a 150 x 200cm mattress.
Will the UK king size help if my partner gets up earlier than me?
It helps on two fronts. The width means their side of the bed is genuinely their side, and the Micro e-Pocket™ springs move independently, so movement on one edge transfers less to the other. If one of you leaves for work hours before the other, the UK king is a sensible upgrade from a double.
Is the Jay-Be Benchmark S7 UK king long enough for someone over 6ft?
At 200cm long, the UK king is 10cm longer than the UK double, and for taller sleepers that length is often the real reason to upgrade. Someone around 6ft gets clear space above their head and below their feet. Bear in mind the mattress is a soft feel, so heavier tall sleepers may still prefer firmer support elsewhere.
Where can I buy the Jay-Be Benchmark S7 in a UK king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's worth checking back before you order. Availability of the UK king can differ from the smaller sizes, since retailers stock each size of this mattress separately.
