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.

- Fits most UK bedrooms: At 4ft 6in x 6ft 3in it works in rooms of 2.6m x 2.8m and up, leaving space for wardrobes and drawers.
- Responsive springs help in a shared bed: The 750 Cortec Quad springs react quickly as you turn, which means less heaving yourself over when your partner is asleep beside you.
- Breathable for two warm bodies: Two sleepers generate more heat than one, and the wool, hemp and flax fillings breathe better than foam across the shared surface.
- Easy to dress and easy to buy for: Double sheets and 200 x 200cm duvets are stocked everywhere, so replacing bedding never becomes a hunt.
- A sensible solo upgrade: Sleeping alone, you get the full 135cm to spread across, with the 2,000 MicroHD springs contouring wherever you settle.
This size suits you if...
You share the bed and your room sits around the typical UK size, where a UK king would leave little walking space, or you sleep alone and want proper room to stretch out. It also makes sense for a guest room that hosts visiting couples, since it fits alongside a wardrobe without dominating. Allow at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm.
Consider another size if...
You and your partner both like space, or one of you is broad-shouldered, because 67.5cm each can feel snug. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and needs a room of at least 2.7m x 2.9m.

Is the Classic 2750 in a UK double big enough for a couple?
For most couples, yes. You each get 67.5cm of width, and the medium-feel pocket springs respond quickly when either of you turns, so you disturb each other less. That said, two restless or larger sleepers may find it a little tight. If your room allows, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Classic 2750 UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That larger figure is what you'd want for bedside tables on both sides with enough room to walk around the foot of the bed. In a smaller second bedroom, the bare minimum still leaves space for a wardrobe.
Should I buy the Classic 2750 in a double or a king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits rooms where a king would dominate. If your bedroom measures at least 2.7m x 2.9m and you share every night, the UK king is the more comfortable long-term choice. Below that, the UK double is the sensible pick.
Is the double Classic 2750 a good choice for a guest room?
It's well suited to one. The 135 x 190cm footprint accommodates visiting couples without swallowing a spare room, and the medium feel sits in the range most guests find agreeable. The natural wool and hemp fillings also breathe well, which helps a bed that may sit unused between visits stay fresh.
Is a UK double Classic 2750 worth it for one person?
Yes, if you like room to move. Sleeping solo you get the full 135cm, which is 45cm more than the UK single, and plenty even with a dog or cat claiming a corner. If budget or floor space is tight, the UK small double gives you 120cm of width and needs a room of at least 2.4m x 2.8m.
