Key benefits
- Room to spread out alone: At 30cm wider than the UK single, you can sleep diagonally or star-shaped without an arm dropping off the side.
- Every inch feels the same: With one layer of high-density reflex foam and no softer top, the firmness is consistent across the whole 120cm width, so the edges feel as usable as the middle.
- Saves floor in tighter rooms: It is 15cm narrower than the UK double, which can be the difference between a wardrobe door opening fully or catching the bed frame.
- Easier up awkward stairs: It arrives vacuum-packed in a box, so you carry a box up a narrow loft staircase instead of wrestling a flat 4ft mattress round the turn.
- Fine for occasional guests: Two visitors can manage a night or two, and the firm, flat surface means neither rolls towards the other the way they might on a softer foam.
This size suits you if...
You sleep alone, like a very firm surface and want more width than a single without losing much floor, or you're kitting out a guest room or loft conversion where couples stay only now and then. It also suits a teenager who has outgrown a UK single when the bedroom can't spare the space for a full double.
Consider another size if...
You share the bed with a partner every night. 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 the UK double.

FAQ's
Can two adults sleep on a Komfi Vitality Ultra Firm UK small double?
For a night or two, yes, and the firm single-layer foam keeps you from rolling together. For every night, it is snug. If you share regularly, the UK double gives 67.5cm each for two sharing, and the UK king gives 75cm each.
What size bedroom 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 drawers. If your room is smaller than that, the UK single needs less: we suggest at least 2.1m x 2.8m for it.
Is the Komfi Vitality Ultra Firm small double a good upgrade for a teenager?
It can be, provided they like a very firm feel. The UK small double is 30cm wider than the UK single and the same length, so they gain width without the bed taking over the room. Lighter teenagers who sleep on their side may find it too hard.
What bedding fits a Komfi Vitality Ultra Firm UK small double?
Look for fitted sheets sold as small double or 4ft, and pair them with a standard double duvet, which gives enough overhang on a 120cm-wide mattress. Avoid double fitted sheets, as they will be loose on this size.
Is the Komfi Vitality Ultra Firm small double long enough for tall people?
It is 190cm long, the same as the UK single and UK double. If you are tall and your feet already reach the end of a standard bed, the UK king is 10cm longer; we suggest at least 2.7m x 2.9m for the UK king.
