Layer Details
- Tencel™ Lyocell sleep surface. A silky, soft-touch material woven to allow airflow, which means moisture is moved away from you rather than trapped at the surface. You should feel drier through the night as a result.
- British Wool Comfort Layer. Flexible, breathable wool from Cheviot sheep that keeps you cool in the summer and warm in the winter. It's a natural temperature regulator, doing quietly what synthetic layers often struggle with.
- Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam while offering the same pressure relief. In practice that means a cocooning, cushioned feel without the heat build-up foam can bring.
- Mirapocket® springs and mini pocket springs. 600 Mirapocket® springs work alongside 1000 mini pocket springs for additional comfort and increased breathability. Pocket springs move independently, which means less disturbance when a partner shifts position.

- A shared size that leaves the room usable: At 135cm wide, the UK double gives a couple a proper bed while leaving space for bedside tables on both sides in most rooms.
- Independent springs matter more when sharing: The 600 Mirapocket® springs and 1000 mini pocket springs move separately, which means less disturbance across 135cm when your partner turns over.
- Wool keeps two sleepers cooler: Two bodies raise the temperature under one duvet, so the British wool layer and breathable Tencel™ surface count for more in a shared double.
- Generous for one: Sleeping solo, the full 135cm width is yours, with room to spread out or share a corner with the dog.
- Easy to dress and easy to fit: Standard double sheets and duvets are sold everywhere, and we suggest a room of at least 2.6m x 2.8m to place it comfortably.
This size suits you if...
You're a couple happy with the traditional shared size and your bedroom would feel cramped around a UK king, or you sleep alone and want space to stretch out. It also suits a guest room that hosts visiting couples, where the medium feel and cool wool surface will keep most guests comfortable without you second-guessing their preferences.
Consider another size if...
You and your partner both want more personal space than 67.5cm each for two people sharing. The UK king is 15cm wider and 10cm longer, and we'd recommend it if your room allows at least 2.7m x 2.9m.

Is the Silentnight British Wool 1600 in a UK double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, which is the long-standing British standard, and the pocket springs limit disturbance when one of you moves. If either of you is broad-shouldered or a restless sleeper, the extra width of the UK king may be worth the larger footprint.
Will the UK double fit a room with bedside tables on both sides?
Usually. We suggest a room of at least 2.6m x 2.8m for the UK double, and at that size you can typically fit a table either side with walking space around the foot of the bed. In a smaller second bedroom, measure carefully before committing to tables on both sides.
How much bigger is the UK king than the UK double?
The UK double is 15cm narrower and 10cm shorter than the UK king. That extra width is roughly a hand span more per person for a couple, and the extra length helps taller sleepers. The trade-off is room space: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Is the UK double a good guest room choice for this mattress?
It's the safest guest size, since it accommodates couples and solo visitors alike in a footprint most spare rooms can take. The medium feel suits a wide range of sleepers, and the wool surface stays temperate, so guests who run hot or cold are both catered for. Standard double bedding keeps things simple too.
