- A firm feel for two: Pocket springs move independently, which means when your partner turns over on their side of the 135cm width, you feel less of it.
- Fits the typical UK bedroom: We suggest at least 2.6m x 2.8m of floor space, which most British double bedrooms clear with room for wardrobes and drawers.
- Bedside tables on both sides: In a room around the 3m x 3m mark, a UK double usually leaves space for a table each side, something a UK king can make tight.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, so replacing bedding is cheap and simple.
- Simpler to get upstairs: At 135cm wide, a UK double is easier to turn on the stairs of an older terrace or a tight new build landing than the larger sizes.
This size suits you if...
You share the bed every night and your room sits comfortably around the suggested 2.6m x 2.8m minimum, you sleep alone but like space to spread out, or a pet has claimed a corner, or you're furnishing a guest room that visiting couples will use and want a firm, supportive surface that holds up over years.
Consider another size if...
Either of you is broad shouldered or a restless sleeper, because 67.5cm each for two people sharing can feel snug on a firm surface. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

Is the Knaresborough 3750 double big enough for two adults?
It works for most couples, though with a firm mattress you'll notice the width more, as there's less sink to settle into. You get 67.5cm each for two people sharing. If either of you sleeps starfish style, the UK king is 15cm wider and 10cm longer, and we'd suggest a room of at least 2.7m x 2.9m for it.
What room size do I need for the Knaresborough 3750 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our own guidance, not the manufacturer's. At the minimum you'll fit the bed and a wardrobe; at the comfortable norm you can add bedside tables on both sides and still open drawers without shuffling round the frame.
Is a UK double or UK king better for this mattress in a smaller bedroom?
The UK double, in most cases. It's 15cm narrower and 10cm shorter than the UK king, and that difference is often what keeps walkways clear on both sides of the bed. If your room comfortably exceeds 2.7m x 2.9m and you both want more space, the UK king becomes the better long term buy.
Does the double suit a guest room?
Yes, and rather well. A firm pocket spring surface divides opinion less than very soft mattresses do, so visiting couples tend to get on with it, and the 135 x 190cm footprint leaves guest rooms feeling like rooms rather than corridors. Double bedding is also the cheapest and easiest to keep spare.
