Layer Details
Memory foam top layer
A 2 cm layer of Neuform memory foam. It gives gentle contouring that eases pressure on your shoulders, hips and joints, without making the mattress feel soft.
Ecofoam base layer
A 13 cm base of high density ecofoam, made from recycled, re-engineered foam. It provides the firm, steady support that defines how this mattress feels.

Key benefits
- Space for one to sprawl: At 30cm wider than the UK single, you can lie on your back with your arms out, and the firm surface keeps you level rather than rolling toward the middle.
- Kinder to a small room: The UK small double is 15cm narrower than the UK double, which means a little more floor beside the bed for a door to swing or a bedside table.
- Even support edge to edge: The 13cm high density ecofoam base runs the full 120cm width, so a solo sleeper who moves around finds the same steady feel wherever they settle.
- Light cushioning on top: A 2cm memory foam layer softens the firmness slightly at shoulders and hips, although side sleepers wanting deep sink may still find it a little unyielding.
- Easier up tight stairs: It arrives vacuum packed and rolled in a box, which means you can carry it up a narrow loft staircase before it opens out in the room.
This size suits you if...
You sleep alone most nights and want more width than a single without giving up much floor, or you're furnishing a compact guest room where a couple stays now and then but nobody shares nightly.
Consider another size if...
You share the bed every night and want room to move without touching. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the Komfi Unity Visco Ortho small double big enough for two people?
For the occasional night, yes. Two adults can share a UK small double for a weekend visit, but it feels close for nightly use. The firm foam limits roll-together a little, yet the width is the real constraint. Couples sharing every night will be more comfortable on the UK double, which gives 67.5cm each.
What room size 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 space to walk round the bed and open a door or wardrobe without squeezing past. In a loft conversion with sloping ceilings, measure the floor where you can stand upright rather than the full room.
What sheets fit a Komfi Unity Visco Ortho small double?
Buy small double (4ft) fitted sheets, sized for 120 x 190cm. Double fitted sheets will bag at the sides. The mattress is 15cm deep, so most standard fitted sheet pockets grip it well. A standard double duvet gives a solo sleeper generous overhang on each side.
Komfi Unity Visco Ortho small double or double: which should I buy?
Pick the UK small double if you sleep alone or your room is tight, since it keeps 15cm more floor clear. The UK double suits couples sharing nightly and needs at least 2.6m x 2.8m by our guidance. Both are the same length, so height is no reason to choose one over the other.
Is a small double a good next mattress for a teenager?
It is a natural step up from a single, adding 30cm of width at the same length, so it usually fits the same alcove or wall. This firm Komfi suits a teenager who sleeps on their back. A teen who curls up on their side may want something softer than this model offers.
