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
- Room for two without filling the room: Each of you gets 67.5cm of width, and we suggest a bedroom of at least 2.6m x 2.8m, so most UK master and second bedrooms can take it.
- Firmer edges help when space is shared: The outer rows of the 800 pocket springs are firmer, which means whoever sleeps nearer the side should feel a little less of that roll-off sensation.
- Bedding is easy to find: Standard double sheets fit, along with a 200 x 200cm double duvet, which helps if you're furnishing a whole home at once and want ordinary bedding.
- Soft enough for side-sleeping couples: The medium soft memory foam lets shoulders and hips sink in, so two lighter side sleepers sharing the UK double should both find it comfortable.
- Space for bedside tables: At 135cm wide, the UK double often leaves room for a bedside table on each side in rooms where a UK king would force you to give one up.
This size suits you if...
You share the bed with a partner who also likes a softer, cushioned feel, and your bedroom is roughly 3m x 3m or a little smaller. It also fits if you're kitting out a guest room for visiting couples, or you sleep alone and the cat or dog usually claims the bottom corner.
Consider another size if...
You're both tall, one of you sprawls, and the bedroom has space to spare. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Bodyshape Boost 800 Pocket Memory double big enough for two people?
For most couples, yes. The UK double gives each of you 67.5cm of width, which suits two average-sized people who don't mind being close. If either of you spreads out at night, the UK king gives 75cm each. Because this mattress has firmer springs around the outer edge, sleeping nearer the side should feel a little more stable.
What size bedroom do I need for a UK double Bodyshape Boost 800?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m being a comfortable size. That usually leaves enough space to walk round the bed and open a wardrobe. If you want bedside tables on both sides, measure from wall to wall before deciding.
Should we choose the Bodyshape Boost 800 in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king, so the king gives 7.5cm more width each. Choose the king if the room has space for it: we suggest at least 2.7m x 2.9m. If your bedroom is closer to 2.6m x 2.8m, the UK double is the better fit.
Bodyshape Boost 800 small double or double for a couple?
The UK double is 15cm wider than the UK small double, and they are the same length. That extra width matters when two people share every night. The UK small double works best in a tighter second bedroom or first flat, and we suggest at least 2.4m x 2.8m for it.
What bedding fits a Bodyshape Boost 800 double mattress?
Use standard double sheets made for a 135 x 190cm mattress, plus a 200 x 200cm double duvet. The mattress is 25cm deep, so check that a fitted sheet's pocket depth suits that before you buy. Double bedding is widely available at every price level.
