- Made for sharing: At 135cm wide you get 67.5cm each for two people sharing, enough for most couples who sleep reasonably close.
- Fits the average UK bedroom: We suggest a room of at least 2.6m x 2.8m, which means it works where the UK king would crowd the walking space.
- Room for bedside tables: In a typical double bedroom this size usually leaves space for a table on each side, so nobody balances a lamp on the floor.
- Budget-friendly for a shared bed: This is one of Silentnight's more affordable ranges, which makes the UK double a practical pick when you're furnishing a whole home at once.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet fit, and both are stocked everywhere at every price point.
This size suits you if...
You share the bed every night and want the classic couples' size from a familiar UK brand, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, or a first flat where the budget has to stretch across every room in the house.
Consider another size if...
You and your partner both like space and your room measures at least 2.7m x 2.9m. The UK king is 15cm wider and 10cm longer than the UK double, and we'd recommend it instead for a noticeably easier share.

Is the Silentnight Just Sleep Relax in a UK double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, which suits pairs who don't mind sleeping fairly close. If one of you is broad-shouldered or a restless sleeper, that shared width can feel a little snug, and the UK king is 15cm wider if your room allows it.
What room size do I need for the Silentnight Just Sleep Relax double?
The mattress itself is 135 x 190cm. We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm, so you can open drawers and walk round the bed without shuffling sideways. That guidance is ours, based on typical UK bedrooms, rather than Silentnight's.
Would the UK double fit a second bedroom or first flat?
Usually, yes. A second bedroom that also needs a wardrobe and a chest of drawers is exactly where the UK double makes sense, because the UK king would dominate the same space. Measure the room against our suggested minimum of 2.6m x 2.8m before ordering, and remember to account for door swing.
Should a solo sleeper choose the UK double or the UK single of this mattress?
If your room is small or the mattress is for occasional guest use, the UK single works, and we suggest at least 2.1m x 2.8m for it. The UK double is 45cm wider at the same length, so for a solo sleeper who spreads out, or shares with a pet, the extra width is well worth having.
How much does the double weigh, and will it get up narrow stairs?
Silentnight doesn't publish a weight or rolled dimensions for this size, so check the retailer's listing before you order, especially if you have a turning staircase in an older terrace or a tight new build landing. At 135cm wide a double is manageable for most homes, but confirm access details with the retailer shown on this page.
