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
- Room to spread out alone: At 30cm wider than the UK single, it lets a solo back sleeper lie flat with elbows out, which suits a firm mattress like this one.
- Kinder to compact rooms: It's 15cm narrower than the UK double, which means a little more clear floor in a box room where the door has to swing past the bed.
- A realistic room minimum: We suggest a room of at least 2.4m x 2.8m, and a loft conversion with sloping ceilings may need more if you want to stand beside the bed.
- Fewer disturbances for guest couples: The 800 pocket springs move independently, so a couple staying the odd weekend should feel each other turning slightly less, although nightly sharing would feel snug.
- Easy to dress: Small double fitted sheets and a standard double duvet both fit, so kitting out a spare room or a teenager's bedroom shouldn't mean hunting for odd bedding.
This size suits you if...
You sleep alone, like a firm bed and have outgrown a single, or you're furnishing a compact guest room where couples stay only now and then.
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 and needs a room of at least 2.6m x 2.8m.

FAQ's
Is the Bodyshape Boost 800 Pocket Ortho UK small double big enough for two?
For occasional guests, yes. Two adults will find it snug, but the independent springs help limit disturbance over a weekend stay. If you'll share every night, the UK double gives 67.5cm each and is the more comfortable choice for regular couples.
What size room do I need for a UK small double Bodyshape Boost 800?
We suggest a room of at least 2.4m x 2.8m, which leaves space to walk round the bed and open a wardrobe. In a box room, check that the door still clears the frame. Measure the stairs and doorways too, then compare the retailers listed on this page.
Bodyshape Boost 800 small double or double: which should I choose?
The UK small double is 15cm narrower than the UK double, and both are the same length. If you sleep alone in a tight room, the small double keeps more floor free. If two of you sleep in it nightly, the UK double needs at least 2.6m x 2.8m and is the better fit.
What bedding fits a Bodyshape Boost 800 Pocket Ortho small double?
Use small double (4ft) fitted sheets with a standard double duvet. The mattress is 24cm deep, so choose fitted sheets with pockets deep enough to tuck fully under a 24cm mattress, or they may ping off at the corners.
Is a UK small double Bodyshape Boost 800 good for a teenager?
It suits a teenager who has outgrown a single: it's 30cm wider than the UK single and the same length, so it won't eat much more of the room. The firm rating suits back sleepers best, although a lighter teen who sleeps on their side may find it hard on the shoulders.
