Key benefits
- Less disturbance at close quarters: With 67.5cm each, you sleep near your partner, so independent pocket springs that limit motion transfer matter more here than on a wider bed.
- Fits rooms a UK king would crowd: At 4ft 6in x 6ft 3in, it usually leaves space for a wardrobe and drawers in a modest main bedroom or first flat.
- Support where two bodies press down: The firmer centre zone sits under the hips and lower back of both sleepers, which helps when two people share one surface.
- Cooler for sharing: Comfort Breathe fibres help regulate temperature, a welcome feature when two people's body heat builds up on a mattress of this width.
- Easy bedding to find: Double sheets are sold almost everywhere, and a 200 x 200cm double duvet fits, so dressing the bed is simple.
This size suits you if...
You share a bed with your partner in an ordinary UK bedroom and want a medium feel with good motion isolation, or you're kitting out a guest room where visiting couples will stay, without the bed taking over the space.
Consider another size if...
You're both tall or like plenty of room to spread out. We'd recommend the UK king instead, which is 10cm longer and gives 7.5cm more each; allow at least 2.7m x 2.9m.

FAQ's
Is a UK double Silentnight Castleton 800 big enough for two adults?
It gives 67.5cm each, which most couples find workable, particularly as the pocket springs limit how much movement travels across the bed. If either of you sprawls, the UK king gives 7.5cm more each and 10cm more length.
What room size do I need for a UK double Castleton 800 Pocket Eco?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. If you want bedside tables on both sides plus a wardrobe, aim nearer the larger figure so you can still walk round the bed.
UK double or UK king for the Silentnight Castleton 800?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is close to 2.6m x 2.8m; the UK king needs at least 2.7m x 2.9m and suits couples who want more space each.
How big is a Silentnight Castleton 800 double in feet?
It measures 4ft 6in x 6ft 3in, or 135 x 190cm. Silentnight doesn't publish a depth for this mattress, so check with the retailer if your bed frame or headboard has depth limits.
Is a UK double Castleton 800 good for a guest room?
Yes, for visiting couples it's a sensible choice: the medium feel suits most back and side sleepers, and it fits a second bedroom more easily than a UK king. Measure stairs and landings first, then compare the retailers listed on this page.
