Layer Details
Castellated reflex foam
A generous top layer of castellated reflex foam, cut in a pattern that is designed to reduce pressure points. For you, that means a medium to firm feel with some cushioning where your body presses down.
Deep castellated foam base
A deep castellated foam base layer that forms the rest of the 22 cm mattress. It gives the foam above something solid to rest on, and the castellated cut suits a bed that raises and lowers.

Key benefits
- The most space this model offers: At 120 x 190cm, this is the biggest size in the PureProfile Coolmax range, giving a lone sleeper on an adjustable bed real stretching room.
- Fits rooms a double cannot: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- 30cm wider than the single: Compared with the UK single of this mattress, you gain 30cm of width at the same length, a noticeable upgrade for anyone who shifts position through the night.
- Works for occasional sharing: A small double can host a couple for the odd night, which suits a guest room or holiday let where nobody sleeps two-up every evening.
- Standard 4ft sizing: Small double is a standard UK size, so fitted sheets and adjustable frames in this width are straightforward to find.
This size suits you if...
You sleep alone on an adjustable or profiling bed and have outgrown the width of a single, or you're furnishing a box room, loft conversion or small second bedroom where a full double would leave no floor space. It also fits a guest room or holiday let where couples stay occasionally rather than nightly. Allow at least 2.4m x 2.8m of room for this size.
Consider another size if...
You share the bed every night, since 120cm is snug for two long term and this model doesn't come any larger. For a solo sleeper in a tighter room, we'd recommend the UK single instead, which needs at least 2.1m x 2.8m.

FAQ's
What room size do I need for a small double adjustable bed mattress?
We suggest allowing at least 2.4m x 2.8m for the UK small double, which gives you space to walk round the bed and open drawers. That's our own guidance rather than Komfi's. If your room falls short of that, the UK single of this mattress needs at least 2.1m x 2.8m.
Is the Komfi PureProfile small double big enough for a couple?
For occasional nights, yes. At 120cm wide it will take two adults for a guest room stay or the odd weekend. As an everyday couples' mattress it's a squeeze, and since the UK small double is the largest size Komfi lists for this model, sharers may need a different mattress altogether.
Does the Komfi PureProfile Coolmax come in a UK double?
No. The UK small double is the biggest size available for this mattress, and at 120 x 190cm it's 15cm narrower than a UK double. That points the range at solo sleepers and profiling beds rather than couples wanting a full-width bed.
How much bigger is the small double than the single in this mattress?
The UK small double is 30cm wider than the UK single, and the two are exactly the same length. If you sleep alone, that extra width is the whole appeal: more room to spread out without stepping up to a footprint your bedroom can't take.
What are the dimensions of the Komfi PureProfile small double?
It measures 120 x 190cm, or 4ft x 6ft 3in. Check that any adjustable base you pair it with is built for a 4ft mattress, and use small double fitted sheets with a standard double duvet. The prices shown on this page are updated as retailers change them.
