- The classic shared size: At 135cm wide, the UK double gives two people 67.5cm each, enough for most couples who sleep reasonably close.
- Fits typical UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which most doubles rooms in flats and terraces can manage.
- Room for bedside tables: In a typical bedroom, the 135cm width usually leaves space for a table on each side, something a bigger size can rule out.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked everywhere, at every price point, so replacing bedding is never a hunt.
- A sensible guest room choice: A UK double sleeps visiting couples comfortably without demanding a large spare room, which is why it remains the guest bed default.
This size suits you if...
You're a couple in a typical UK bedroom and want a bed that shares well without dominating the floor space, you're furnishing a guest room that needs to sleep two visiting adults, or you sleep alone and want genuine room to spread out. It also suits older terraces and tight new build landings, where a 135cm mattress is far easier to turn up a staircase than a king.
Consider another size if...
You and your partner both want more personal space than 67.5cm each. We'd recommend the Silentnight Just Sleep Serene in a UK king instead: 15cm wider and 10cm longer, needing a room of at least 2.7m x 2.9m.

Is the UK double the smallest size the Silentnight Just Sleep Serene comes in?
Yes. The Just Sleep Serene is sold in UK double, UK king and UK super king only, so there's no single or small double option. If your bed frame is smaller than a double, this model won't fit it and you'll need to look at a different mattress.
Will the Just Sleep Serene in a UK double fit my bedroom?
The mattress measures 135 x 190cm, and we suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. In most UK bedrooms that leaves space to walk round the bed and, usually, room for bedside tables on both sides.
How much space does each person get on the UK double Just Sleep Serene?
Two people sharing get 67.5cm each. That's fine for most couples, although if one of you is broad shouldered or a restless sleeper, it can start to feel snug. In that case the Just Sleep Serene in a UK king, 15cm wider, is the better long term buy.
Should I buy the Just Sleep Serene in a UK double or size up to the UK king?
It usually comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and needs a room of at least 2.6m x 2.8m against 2.7m x 2.9m for the king. If your room clears the larger figure and you share every night, the extra width is worth having.
