Layer Details
Memory foam layer
A memory foam layer that adapts around your body. That gives you a sink-in, cushioned feel and helps ease pressure.
Reflex foam layer
A layer of Reflex foam that offers durable comfort. It adds resilience beneath the memory foam so the surface should keep its feel.
Soft white fibres layer
Soft white fibres that encourage open airflow. This helps dispel heat and moisture so you sleep more comfortably.
Pocket spring core
A core of 800 pocket springs, each in its own fabric pocket, with firmer springs on the outer rows. This gives supportive, responsive sleep and reduces the roll-off feeling at the edges.

Key benefits
- A soft feel for lighter bodies: The medium soft memory foam top gives under small frames, which means children and slim teens should feel cushioned at the shoulder and hip rather than perched on top.
- Edges you can sit on: Firmer springs line the outer rows, which matters on a narrow bed where you sit on the side to read, dress or get up every morning.
- Leaves room for a desk: At 90cm wide, the UK single leaves space beside it for a wardrobe, a desk or toy storage in a child's room that has to hold all three.
- Two can fit in a guest room: A pair of UK singles gives two visitors a bed each, and with a gap between them, friends or siblings won't disturb each other.
- Cooler under a sloping ceiling: Under the memory foam sits a layer of soft white fibres meant to encourage airflow, a welcome detail in a loft conversion bedroom that tends to hold heat.
This size suits you if...
You're buying for a child or teenager who sleeps alone, you're furnishing a compact spare room or loft conversion where only a narrow bed will fit, or you want a soft, cushioned single for a lighter adult in a first flat.
Consider another size if...
You share the bed every night, or you already find a narrow bed cramped. 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 it.

FAQ's
Will a UK single Bodyshape Boost 800 fit a bunk bed or mid sleeper?
The mattress is 25cm deep, so the width is the easy part. On a raised frame, the deciding figure is the maximum mattress depth set by the frame's maker, because a deep mattress cuts into the height of the guard rail. Check the bunk or cabin bed instructions before ordering, and stick to their limit.
Is a UK single Bodyshape Boost 800 long enough for a teenager?
The UK single is 190cm long (6ft 3in), which suits most growing teens. If yours is already very tall, the UK king is 10cm longer, although it also needs far more floor space: we suggest at least 2.7m x 2.9m for the UK king.
What size room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m for a UK single. That leaves enough floor to walk around the bed and open a wardrobe door. In a shared children's room with two singles, you'll want noticeably more, so measure for both beds and a walkway between them.
Is the Bodyshape Boost 800 a good mattress for a child's single bed?
For most children, yes. It's rated medium soft, and lighter bodies sink into memory foam less than adults do, so the feel tends to read as cushioned rather than saggy. It's single-sided, so rotate it top to toe now and then. Bodyshape doesn't publish a weight limit, so check with the brand for an older, heavier teen.
What sheets and duvet fit a single Bodyshape Boost 800?
Standard UK single fitted sheets fit the 90 x 190cm footprint, and a single duvet (135 x 200cm) covers it. Because the mattress is 25cm deep, look for fitted sheets labelled as deep or extra deep so the corners stay tucked under.
