Layer Details
Neuform memory foam top layer
A layer of Neuform memory foam sits on top, aimed at comfort from edge to edge. It gives the softer, contouring feel of memory foam, which suits the medium-soft feel on record.
Pocket springs
1000 body-reactive pocket springs, each in its own cloth sleeve, spread pressure evenly. For you, that should mean a more responsive, supported feel than foam alone.
Ecofoam core
An Ecofoam core is layered with the pocket springs and has a reduced carbon footprint. It forms the base of the mattress, so you get the springs' support with a lower environmental impact.

Key benefits
- 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 toy storage.
- Boxed delivery suits awkward spaces: The rolled format goes up bunk ladders of stairs, through box-room doorways and under loft slopes far more easily than a flat mattress.
- Hybrid feel for growing sleepers: Memory foam contours while pocket springs keep the surface supportive, which means children and teens get comfort without the fully sunk-in feel of all-foam.
- Works for guest and spare rooms: A single fits a study that doubles as guest space, and two singles fit where one larger bed would crowd the walkway.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teenager's first proper mattress, you sleep alone and want to keep floor space free in a compact bedroom, or you're kitting out a spare room, student let or first flat where the frame is already provided and only the mattress is missing.
Consider another size if...
You're an adult who likes to spread out, or you occasionally share the bed. The UK double of this mattress would suit you better, at 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Will the Komfi Unity single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. The one caution is depth: Komfi doesn't publish a depth for this mattress, and raised frames often set a maximum so the guard rail stays effective. Check your frame's limit with the retailer before ordering.
What room size do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk alongside the bed and open drawers or a wardrobe. That's our own guidance rather than Komfi's, and most box rooms and loft conversions clear it comfortably.
Is the Komfi Unity UK single good for a child or teenager?
Yes, with a small hedge. The mix of memory foam and pocket springs gives contouring without the sunk-in feel some children dislike, and the single size will last through the teenage years. Komfi doesn't publish a firmness rating, so if your child has a strong preference, ask the retailer first.
How much smaller is a UK single than a small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length at 190cm. If a slightly wider solo bed appeals and your room allows at least 2.4m x 2.8m, the UK small double of this mattress is the next step up.
Can I fit two Komfi Unity singles in one guest room?
Often, yes. Each mattress is 90cm wide, so two singles with a walkway between them suit guest rooms that host pairs who aren't a couple, or siblings sharing. Measure your room against the beds plus a gap you can actually walk through, and compare the retailers listed on this page for each.
