Layer Details
Reflex foam
A layer of Reflex foam that shapes around your body. It gives a cushioned yet sturdy feel, so the firm surface isn't harsh.
Soft white fibres
Soft white fibres that increase airflow to help dispel heat. This means the mattress should feel fresher through the night.
Dense polyester fibres
Two layers of dense polyester fibres that enhance the firm feel. They also give the spring system extra support.
Pocket springs
A core of 800 pocket springs, each encased in its own fabric pocket. Each spring moves independently, so the mattress can respond to your body.

Key benefits
- Leaves room for everything else: At 3ft x 6ft 3in, the UK single leaves floor clear for a desk, a wardrobe and toy storage in a small child's bedroom.
- Firm support for one back sleeper: The firm pocket spring core suits a back-sleeping teenager or adult, and the Reflex foam on top means the surface feels cushioned rather than hard.
- Two can sit side by side: Two UK singles make a flexible guest room for friends or siblings who would rather not share a bed, with a walkway between them.
- A known depth for raised frames: Bodyshape gives a depth of 24cm, so you can check it against a cabin bed's or mid sleeper's maximum before you order.
- Fresher in a small, warm room: Soft white fibres increase airflow, which means the mattress should feel a little fresher in a box room or loft space that holds heat.
- Simple bedding: Standard single sheets fit, and a single duvet at 135 x 200cm completes the bed without hunting for unusual sizes.
This size suits you if...
You sleep alone, mostly on your back, and like a firm bed, or you are furnishing a teenager's room or a loft conversion where every bit of floor counts and a firm, supportive mattress is what you want.
Consider another size if...
You want space to spread out or often share the bed. The UK small double would suit you better: it is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the Bodyshape Boost 800 Pocket Ortho UK single fit a bunk bed?
It is 24cm deep. Bunk beds, cabin beds and mid sleepers usually set a maximum mattress depth so the guard rail stays high enough to stop a child rolling out. Check the frame maker's guidance, and only order if 24cm sits within it.
Is the Bodyshape Boost 800 UK single good for a child?
It can be, with a condition. It is rated firm, and lighter sleepers may find it hard on the shoulders and hips, particularly if they sleep on their side. A heavier teenager who sleeps on their back is a better match than a small child who curls up.
What size bedroom do I need for a UK single Bodyshape Boost 800?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough room to walk round the bed and open a wardrobe, which matters in a child's room or a spare room that also holds a desk.
Is a UK single long enough for a tall teenager?
The UK single is 190cm long. If your teenager is already close to that height, the UK small double will not help, as it is the same length. The UK king is 10cm longer, though we suggest at least 2.7m x 2.9m for that size.
Two singles or one small double Bodyshape Boost 800 for a guest room?
Two UK singles let guests who are not a couple sleep apart, and you can push them together if needed. A single UK small double is 30cm wider than one UK single and needs at least 2.4m x 2.8m. Measure the room first, then compare the retailers listed on this page.
