Key benefits
- Two feels in a modest footprint: Each of you gets your preferred side, soft or firm, without giving up the room a bigger bed would take from wardrobes and drawers.
- Fits a typical UK bedroom: We suggest a room of at least 2.6m x 2.8m, which means many second bedrooms and first flats can take it with space to walk around.
- Zoned springs help on a narrower bed: Silentnight says the zoned Mirapocket springs prevent roll-together, which matters more when you each have 67.5cm rather than the extra room of a UK king.
- Familiar British measurements: At 4ft 6in x 6ft 3in, it's the size many older bed frames and headboards were built for, so replacing a worn double is usually straightforward.
- Easy, widely sold bedding: Standard double sheets fit, along with a 200 x 200cm double duvet, so you shouldn't need to hunt for specialist linen.
- A good guest room choice: Visiting couples with different tastes can each pick a side, which suits a spare room where you can't predict who'll be sleeping.
This size suits you if...
You share the bed with someone who wants a different firmness from you, your bedroom has room for a double but not much more, and you'd like bedside tables on both sides without squeezing past the bed frame.
Consider another size if...
Either of you sprawls, or you'd regularly share with a pet as well. We'd recommend the UK king instead, which gives 7.5cm more each and needs a room of at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a Silentnight Yours & Mine UltraGel UK double?
Each of you gets 67.5cm when sharing a UK double. That's enough for most couples who sleep fairly still, although it can feel a little close if one of you sprawls. Silentnight says the zoned Mirapocket springs stop you rolling towards the middle, which helps you stay on your own soft or firm side.
What size bedroom do I need for a UK double Yours & Mine mattress?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m giving you comfortable room for bedside tables and a wardrobe. In a smaller second bedroom, measure where drawers and doors open before choosing, as the bed frame usually adds a few centimetres to the 135 x 190cm mattress.
Silentnight Yours & Mine UK double or UK king: which should we get?
The UK double is 15cm narrower and 10cm shorter than the UK king, giving you 7.5cm less each. If your room only just clears our 2.6m x 2.8m suggestion for a UK double, stay with it. If you have at least 2.7m x 2.9m and either of you is tall or restless, the UK king is the better fit.
What bedding fits a 33cm deep UK double mattress?
Standard double sheets and a 200 x 200cm double duvet fit the UK double. The Yours & Mine is 33cm deep, so check the pocket depth on any fitted sheet before buying, as shallower sheets can struggle to tuck under the corners of a thicker mattress.
Will a UK double Yours & Mine fit up narrow or turning stairs?
Measure the tightest turn on your stairs and landing against the 135cm width and 33cm depth, especially in older terraces or compact new builds. A pocket spring mattress of this size is easier to manoeuvre with two people, one at each end. Once you're sure it'll get upstairs, compare the retailers listed on this page.
