Key benefits
- The traditional couples' footprint: At 135 x 190cm, the UK double is the long standing British size for two, so it fits rooms where a larger bed would crowd everything else.
- 67.5cm each when sharing: Two people get 67.5cm each across the width, enough for occasional guests, though couples who sleep here every night may feel a little snug.
- Boxed delivery suits awkward access: Because it arrives compressed and rolled, it turns the tight stairs of an older terrace or a narrow new build landing far more easily than a flat mattress.
- A sensible fit for a guest room: Visiting couples can share it comfortably for a few nights, and the low price means you're spending accordingly on a bed used a handful of times a year.
- Bedding is easy and cheap: Double sheets and a 200 x 200cm duvet are stocked everywhere at every price, which matters if you're furnishing a whole home on a tight budget.
This size suits you if...
You're kitting out a guest room or a first flat and want a shared-size bed without spending much, you're buying for a teenager who's outgrown a single and has the floor space, or you're a solo sleeper who likes room to spread out. Allow at least 2.6m x 2.8m of bedroom, with around 3m x 3m the comfortable norm if you want bedside tables on both sides.
Consider another size if...
You're a couple planning to sleep on it every night and want more space than 67.5cm each. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Komfi Unity Regular UK double big enough for two adults?
For occasional use, yes. At 135 x 190cm you each get 67.5cm of width, which works for visiting couples in a guest room. As an everyday bed for two adults it's less convincing, partly because of the width and partly because Komfi pitches this mattress towards kids and teenagers rather than long-term adult use.
What room size do I need for the Komfi Unity Regular in a double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our own guidance, not the manufacturer's, and it leaves space for a wardrobe and drawers. If you want bedside tables on both sides, aim for the roomier end of that range.
Will the boxed UK double fit up narrow stairs?
This is where the boxed format helps most. The mattress arrives rolled and compressed, so it's a manageable one-person carry around the turning stairs of an older terrace or a tight new build landing. A flat double at 135cm wide would be a much harder job. Once it's in the room, unroll it and let it expand.
Should I get the Komfi Unity Regular in a double or a single for a teenager?
It depends on the room. The UK double is 45cm wider than the UK single and the same length, so a teenager gets far more room to sprawl. We suggest at least 2.1m x 2.8m for the UK single, so if the bedroom is small, the single keeps floor space free for a desk and wardrobe.
What bedding does the double Komfi Unity Regular take?
Standard UK double bedding: double fitted sheets for the 135 x 190cm footprint and a 200 x 200cm double duvet. Both are sold everywhere at every price point, which suits this mattress well, since a budget bed paired with budget-friendly bedding keeps the whole setup cheap, whether it's for a spare room or a first flat.
