Layer Details
- Knitted cover. A soft knitted top that adds cosiness and warmth while allowing enhanced airflow. In practice, that means a gentler first touch without trapping quite as much heat as some foam mattress covers.
- Memory Foam. A 3cm comfort layer that adapts to the contours of your body and moulds to your shape, which means pressure points like hips and shoulders get some cushioning. It's a fairly slim layer, so the firm base makes itself felt through it.
- Reflex Foam. A 17cm supportive base that is durable and resilient, holding its shape over an extended period. This is where the firm feel comes from, and it should keep the mattress performing consistently for longer.

- Room to spread out, alone: At 120cm wide it gives a solo sleeper considerably more space than a UK single, which means you can shift position freely without an arm hanging off the edge.
- Fits rooms a double crowds: It's 15cm narrower than a UK double, which can be the difference between a door that clears and one that doesn't in a box room or studio.
- Firm feel suits solo back and front sleepers: The 17cm reflex foam base gives a solid, resilient surface, so if you sleep alone on your back or front you'll feel steady, even support.
- Slim depth, easy to handle: At 20cm deep and in a 4ft size, this is a manageable mattress to move up narrow stairs or into a loft conversion.
- Standard 4ft bedding and frames: The UK small double is a standard UK size, so fitted sheets and bed frames are easy to find on the high street.
- Copes with occasional couple use: The firm reflex base resists sagging, so a guest room mattress that hosts two people now and then should hold its shape well.
This size suits you if...
You're a solo adult, or a teenager who has outgrown a single, and you want more width without giving up the floor space a full double demands. It also suits a guest room or holiday let where couples stay occasionally rather than nightly, and you'd rather they had firm, no-fuss support than a plush surface. Allow at least 2.4m x 2.8m of room space.
Consider another size if...
You share the bed every night, as 120cm is snug for two on a firm surface with little give. We'd recommend the UK double instead, which is 15cm wider; allow at least 2.6m x 2.8m for it.

Is a small double big enough for one adult to sleep on every night?
Yes, comfortably. The UK small double is 120cm wide, 30cm more than a UK single, which means a solo adult can starfish, roll over and change position without running out of mattress. The firm feel of this Bodyshape Ortho suits back and front sleepers particularly well when they have that extra width to use.
Can a couple share the Bodyshape Ortho in a small double?
For occasional nights, yes, which makes it a reasonable guest room choice. For every night, 120cm is tight for two adults, and because this mattress is firm with only a 3cm memory foam layer, there's little sink to soften a cramped position. Couples sleeping together nightly would be better served by the UK double.
Will the small double Bodyshape Ortho fit in a box room or studio flat?
This is where the size makes sense. At 120 x 190cm it's 15cm narrower than a UK double, which often decides whether a door still opens fully or you can walk down one side of the bed. We suggest a room of at least 2.4m x 2.8m for comfortable movement around it.
Is this mattress easy to get into a loft room or up narrow stairs?
Easier than most. The 20cm depth and 4ft width make it one of the more manageable combinations to carry, helpful in loft conversions and older houses with tight staircases. It has no handles, though, so repositioning it on the base takes a bit of gripping and shuffling.
What size bedding does a small double take?
Small double (4ft) fitted sheets are made specifically for the 120 x 190cm footprint, and they're widely stocked because it's a standard UK size. A standard double duvet works fine on top, and for one sleeper it drapes generously over both sides.
