Layer Details
- Cover. A cover of wool and natural viscose, fibres that are soft to the touch and naturally fire retardant. That means no chemical fire-retardant treatments are needed to meet safety standards.
- Comfort fillings. Multiple layers of wool, hemp and flax sit beneath the cover, which means a cosy surface feel that also breathes well. Natural fibres like these tend to sleep cooler than synthetic foams.
- MicroHD springs. A layer of 2,000 MicroHD springs sits above the core spring unit. These smaller springs add responsiveness and a more contouring feel at the surface.
- Support layer. Two layers of Ecotex fibres, made from recycled materials, support the spring system. A small sustainability point, and it gives the springs a stable base to work from.
- Core springs. The core holds 750 Cortec Quad springs, a design where four springs are fused into a single pocket. In practice that means increased responsiveness, so the mattress reacts quickly as you shift position.

- Room to sleep apart, together: At 75cm each for two people sharing, you can both turn over without negotiating, which matters when one of you shifts position often.
- Length for taller sleepers: The 200cm length gives anyone approaching or over six foot proper coverage, so feet stay on the mattress rather than hanging past the end.
- Responsive springs across a wider bed: The Cortec Quad core reacts quickly as you move, which means an early riser can slip out at 5am with less of a wrestle.
- Pocket springs on your own side: Each spring sits in its own pocket, so movement on one half of the 150cm width is less likely to travel across to yours.
- Natural fillings over a bigger surface: Wool, hemp and flax breathe well, useful when two bodies are warming a shared bed all night.
- A standard size to shop for: UK king (5ft x 6ft 6in) bedding and bases are everywhere, so frames, sheets and duvets are easy to find.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, one of you is up hours before the other and wants to leave without waking the whole bed, or someone in it is tall enough that the extra 200cm length is the real draw. It also suits couples whose dog has quietly claimed a corner and shows no sign of giving it back.
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 around 2.6m x 2.8m.

Is the Classic 2750 UK king long enough for a tall sleeper?
Yes, for most. The UK king is 200cm long, 10cm more than the UK double, which is often the difference between feet on the mattress and feet dangling off it. If one of you is over six foot, that added length is arguably a bigger upgrade than the extra width.
How much space do two people get on the Classic 2750 in a UK king?
75cm each for two people sharing, across the full 150cm width. That is 15cm more than a UK double offers between you, enough to change position without brushing elbows. The pocket springs help here too: each one compresses independently, so your partner's tossing is less likely to reach your side.
What room size do you need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m, with more feeling noticeably more comfortable once wardrobes and bedside tables go in. New build master bedrooms can be tighter than they first appear, so measure with the furniture in mind, then check the walking space left on each side of the bed.
Should I buy the Classic 2750 in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king, and the two are the same length, so this is purely a width decision. If your room comfortably clears 3m x 2.9m and you want maximum space, size up. If not, the UK king remains a genuinely generous bed for two.
Is the UK king worth it over the double for this mattress?
For most couples, yes. The UK king is 15cm wider and 10cm longer than the UK double, and on a responsive spring mattress like this one, that gap reduces how much of your partner's movement you notice. Compare the retailers listed on this page, as prices for both sizes change regularly.
