- Real stretching room for one: At 120cm wide, it's 30cm wider than a UK single, which means a solo adult or growing teenager can spread out properly.
- Fits rooms a double can't: It's 15cm narrower than a UK double, so a box room, studio or loft conversion keeps walking space either side of the bed.
- Boxed delivery suits tight spaces: The rolled, compressed format goes through doorways and up narrow staircases far more easily than a flat mattress, and setup is a one-person job.
- A sensible teenage upgrade: Komfi pitches the Unity Regular at kids and teenagers, and the UK small double gives a teen who's outgrown a single room to grow into.
- Standard UK size for bedding: 4ft is a standard UK size, which means small double frames and fitted sheets are easy to find on the high street.
This size suits you if...
You're a solo adult or teenager who's outgrown a UK single but can't spare the floor space a full double takes, or you're furnishing a compact guest room, rental or holiday let where couples will only stay the odd night. It also suits a downsized bedroom where the bed has to fit the new room rather than the old one, and the budget price fits a second bedroom nicely.
Consider another size if...
You share the bed every night, or you're a heavier adult wanting a long-term main mattress. For nightly couples we'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m for it.

Is the Komfi Unity small double a good size for a teenager?
Yes, arguably its best use. Komfi positions the Unity Regular towards kids and teenagers, and the UK small double gives 30cm more width than a UK single at the same 190cm length. That means a teenager who's started hanging off the edges of a single gets proper room without the bed swallowing the whole floor.
What size room do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves enough space to walk around the bed and open drawers or a wardrobe. If your room is smaller than that, a UK single may be the more comfortable fit, since it's 30cm narrower and the same length.
Can a couple sleep on the Komfi Unity in a small double?
For occasional nights, yes, which makes it a reasonable guest room choice where nobody sleeps on it nightly. As an everyday couples' bed it's a squeeze at 120cm wide, and Komfi aims this mattress at kids and teenagers anyway, so two adults sharing every night would be better served by the UK double.
Should I choose the Komfi Unity in a small double or a UK double?
It usually comes down to the room. The UK small double is 15cm narrower than the UK double and the same length, so it fits box rooms and studios where a double would dominate. If you have at least 2.6m x 2.8m to play with and share the bed regularly, the UK double is the safer pick.
Does the Komfi Unity small double work for a guest room?
It's well suited to one. The 120 x 190cm footprint fits a compact second bedroom in a home or holiday let, solo guests get generous space, and couples can share for a night or two. The budget price also makes sense for a bed that's slept on occasionally rather than every night.
