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.

Key benefits
- Fits where space is tight: At 90cm wide, this size leaves room for a desk, wardrobe and toy storage in a child's bedroom, or slots under a loft conversion slope.
- Sensible for raised frames: The 20cm depth sits comfortably below the safety rails on most bunks and mid sleepers, where a taller mattress would be unsuitable.
- Firm support for growing sleepers: The 17cm reflex foam base gives children and teens a stable, resilient surface that holds its shape rather than sagging where they sleep.
- Guest rooms and studies: A single suits a spare room that doubles as an office, or two singles where you host more than one guest at a time.
- Easy, affordable bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are among the cheapest and easiest bedding to find in UK shops.
This size suits you if...
You're kitting out a child's or teenager's room and want a firm, durable mattress that can move to a bunk or mid sleeper later, you need a guest bed for a spare room that also works as an office, or you're a solo adult in a compact bedroom, student room or first flat where a 90cm width is the practical limit.
Consider another size if...
You're an adult who spreads out in the night or simply finds 90cm restrictive. The UK small double is 30cm wider and the same length, and we suggest allowing at least 2.4m x 2.8m of floor space for it.

FAQ's
What are the dimensions of the Bodyshape Ortho mattress in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That is the standard one-person size in the UK, so it fits ordinary single frames, divans, bunks and mid sleepers without any sizing surprises. Standard single sheets and a 135 x 200cm single duvet fit it.
Is the Bodyshape Ortho single suitable for a bunk bed or mid sleeper?
Yes, and it's one of this size's stronger uses. At 20cm deep it should sit below the guard rails on most raised frames, where deeper mattresses can be unsafe, and the firm reflex foam base copes well on slatted bunk bases. Check your frame's maximum mattress depth before ordering, as designs vary.
Is the Bodyshape Ortho single a good mattress for a child or teenager?
It suits most children and teens well. The firm feel gives growing bodies steady support, and the durable reflex foam base resists the dips that cheap kids' mattresses often develop. One caution: very light side sleepers may find it a little unyielding, as the memory foam comfort layer is only 3cm thick.
How much floor space do I need for a UK single in a small bedroom?
We suggest allowing at least 2.1m x 2.8m, which is our guidance rather than the manufacturer's. That leaves enough walkway to make the bed and open a wardrobe. In practice a single fits almost any UK bedroom, including box rooms and loft conversions where the ceiling slope narrows the usable footprint.
Should I choose the UK single or size up to the UK small double?
For a child, a bunk, or a compact spare room, the UK single is the sensible choice. If it's an adult's everyday bed and the room allows, the UK small double is 30cm wider and the same length, giving a solo sleeper noticeably more room to turn. Allow at least 2.4m x 2.8m for the UK small double.
