Key benefits
- Suits a typical bedroom: We suggest a room of at least 2.6m x 2.8m, so the UK double fits many second bedrooms and first flats where a UK king would crowd the floor.
- Cooling helps when you share: Two people sleeping close together build up heat, and the CoolEase cover and breathable latex are designed to draw it away, which means less chance of waking up warm.
- Zoned support on each side: The Mirapocket zoned support system aims to support each of you where your body needs it, which matters a little more when neither of you can spread out.
- Bedding is easy to find: Double sheets are stocked everywhere and a 200 x 200cm double duvet fits, handy if you're furnishing a whole home at once and the budget is spread thin.
- Space for bedside tables: At 15cm narrower than the UK king, the UK double often leaves floor for a bedside table on each side in a room near our suggested minimum.
This size suits you if...
You share with a partner and your bedroom sits nearer our suggested 2.6m x 2.8m than the comfortable 3m x 3m, you're setting up a guest room for visiting couples, or you sleep alone and want room to spare when the dog or cat claims a corner.
Consider another size if...
You and your partner both sprawl, or one of you is tall and already finds a standard length short. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's
Is a UK double Silentnight Relieve 3000 big enough for two adults?
It gives each of you 67.5cm, which most couples used to sharing find comfortable. That is 7.5cm less each than the UK king, so if either of you moves about a lot or you've felt cramped on a double before, the UK king is the safer choice.
What size room do I need for a UK double Silentnight Relieve 3000?
We suggest at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable. If you want bedside tables on both sides plus a wardrobe and drawers, lean towards the larger figure so you can still walk round the bed without squeezing past furniture.
Silentnight Relieve 3000 UK double or UK king: which should we choose?
The UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it. If your room clears that comfortably, the extra width is noticeable for two. In a smaller bedroom, the UK double keeps the room usable while still giving you each 67.5cm.
Will a UK double mattress get up narrow stairs?
Silentnight doesn't publish a depth for this mattress, so measure your stairwell and any landing turns against the 135 x 190cm footprint before ordering. Older terraces with turning stairs and tight new build landings are where problems usually happen. Once you're sure it will fit, compare the retailers listed on this page.
Is a double worth it over a small double for a couple?
For two adults, usually yes. The UK double is 15cm wider than the UK small double and the same length, which makes a real difference when you share every night. We suggest at least 2.4m x 2.8m for the UK small double, so it only wins if your room is genuinely tight.
