Layer Details
Reflex foam top layer
A 3cm layer of high-density Reflex foam sits at the top of the mattress. It adds a layer of cushioning over the springs, so the surface feels softer than bare springs would.
Pocket spring core in Ecofoam
Traditional pocket springs, each moving independently, are encased in Ecofoam made from 100% recycled foam. Because the springs work separately, the mattress can respond to each sleeper, which means less disturbance from a partner's movement. The recycled foam is a plus if you prefer to cut down on waste.

Key benefits
- Fits the smallest rooms: At 90cm wide, it leaves floor space for a desk, wardrobe and toy storage in a child's bedroom, and we suggest a room of at least 2.1m x 2.8m.
- Boxed delivery suits awkward access: It arrives compressed and rolled, which means narrow staircases, loft conversions and student flats stop being a problem on delivery day.
- Pocket springs at a low price: The 1000 independently moving pocket springs offer proper support at a price that suits a guest bed or a first flat where budget matters.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and they're the cheapest and most widely stocked bedding of any UK size.
- Pairs up neatly for guests: Two UK singles suit a guest room or siblings sharing, giving each sleeper their own mattress with a walkway between the beds.
This size suits you if...
You're buying for a child or teenager, kitting out a spare room or study that occasionally hosts guests, or you're a solo adult in a compact room, perhaps a student flat or loft conversion where only a narrow footprint fits under the slope. It also suits anyone furnishing on a budget who still wants pocket springs rather than an all-foam feel.
Consider another size if...
You're an adult who shares the bed, or a solo sleeper who likes room to spread out. We'd recommend the UK double instead, which is 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 Pocket 1000 single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. The catch is that raised frames often have a maximum mattress depth for guardrail safety, and Komfi doesn't publish a confirmed depth for this model, so check the measurement with the retailer before buying for a bunk.
Is a UK single big enough for an adult on this mattress?
At 90cm wide and 190cm long, it works for a single adult of average height in a compact room, and the pocket springs support one sleeper well. Taller adults or anyone who spreads out in the night may feel restricted, in which case the UK double, 45cm wider, is the safer choice.
Is the Komfi Unity Pocket 1000 single good for a child's room?
Yes, this is arguably where it makes most sense. The single is the standard UK children's size, the low price suits a bed a child will outgrow, and the 90cm width leaves space for a desk and storage. We suggest a room of at least 2.1m x 2.8m.
Can two singles work instead of one double in a guest room?
Yes, and it's a flexible setup: two 90 x 190cm mattresses suit couples and solo guests alike, and pocket springs mean each bed supports its sleeper independently. You'll need enough floor space for both beds plus a walkway between them, so measure the room before committing.
How is the single delivered and is it easy to move upstairs?
It arrives compressed, rolled and boxed, and the single is the smallest boxed version of this mattress, so it's the easiest to carry up narrow stairs, into a loft conversion or through a student flat's tight hallway. Once unrolled and expanded it can't be re-compressed, so unbox it in the right room.
