Layer Details
- Fits almost any room: At 90cm wide, it leaves floor space free in a child's bedroom that also has to hold a wardrobe, a desk and a growing pile of toys.
- Made for the age group: Komfi pitches the Unity Regular at kids and teenagers, and the UK single is exactly the size that stage of life calls for.
- One-person setup: Boxed delivery means you can carry it upstairs alone and unroll it in place, useful when the room is up a narrow staircase.
- Sensible for spare rooms: A spare room doubling as an office rarely has space for anything wider, and a budget single covers occasional guests without a big outlay.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and least expensive of any size, which keeps the running costs as low as the mattress itself.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, you need two beds plus a walkway in a room siblings share, or you want a low-cost mattress for a spare room, student flat or rental where the frame is already provided. Allow at least 2.1m x 2.8m of floor space and the UK single fits comfortably.
Consider another size if...
You're an adult who wants room to stretch out, or a couple. The UK single is 45cm narrower than the UK double, so we'd recommend the UK double instead, allowing at least 2.6m x 2.8m of floor space.

Will the Komfi Unity Regular UK single fit a bunk bed or mid sleeper?
The footprint matches: bunk beds, cabin beds and mid sleepers in the UK take a standard 90 x 190cm single. The catch is depth. Raised frames often specify a maximum mattress depth for safety rails, and Komfi doesn't publish a depth for the Unity Regular, so check with the retailer against your frame's limit before buying.
Is the Komfi Unity Regular UK single suitable for an adult?
For a single adult of average build, the UK single is the standard one-person size and works fine, particularly in a first flat or student room. That said, Komfi positions this mattress towards kids and teenagers, and heavier adults or anyone wanting a long-term everyday bed would be better served by a mattress with fuller published specifications.
How much space does a UK single need in a child's bedroom?
We suggest allowing at least 2.1m x 2.8m of floor space. In practice the 90cm width is what makes the UK single so useful in a child's room: it leaves space alongside for a desk, wardrobe and toy storage. In a loft conversion, the narrow footprint also tucks under a sloped ceiling more easily than wider sizes.
Can two Komfi Unity Regular singles work for a shared or guest room?
Yes, and it's a common setup. Two UK singles suit siblings sharing a room with a walkway between the beds, or a guest room where two separate beds are more flexible than one double. Because it ships rolled in a box, getting two mattresses up the stairs is far easier than with flat-packed traditional ones.
Should I get the UK single or the UK small double for a teenager?
The UK single is 30cm narrower than the UK small double, and both are the same length. If the room is tight, the UK single keeps floor space free. If a teenager wants more room to sprawl and the bedroom allows at least 2.4m x 2.8m, the UK small double is a reasonable step up without going to a full double.
