Sewn-in pillow top
A sewn-in pillow top filled with British wool, cotton, kapok, Himalayan allo, Solotex and eOlus recycled fibres. It adds extra cushioning over the medium-rated mattress, so the surface feels softer.
ReActivePro pocket spring core
ReActivePro pocket springs with six active turns, with Triple Edge Protection at the edges. The springs give the support underneath, and the protected edges help the sides hold up when you sit on them.

Key benefits
- Room to spread out alone: It's 30cm wider than a UK single, which means a restless solo sleeper can turn, sprawl or curl up without hitting the edge.
- Kinder to a small floor plan: Being 15cm narrower than a UK double, it can leave enough clearance for a door to swing or a wardrobe to open in a tight room.
- Usable right to the sides: Triple Edge Protection helps the edges hold up when you sit on them, which matters on a narrower bed where you'll often perch near the side.
- Cushioned medium feel for one: The sewn-in pillow top softens the surface of a medium-rated mattress, so a single side or back sleeper gets plenty of comfort across the whole width.
- Easy to dress: The UK small double is a standard 4ft size, so fitted sheets labelled small double and an ordinary double duvet are simple to find.
This size suits you if...
You sleep alone but feel cramped on a single, your bedroom is too small to give up the floor a 4ft 6in bed would take, or you're furnishing a spare 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; we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the Hypnos Pillowtop Select 1200 UK small double big enough for two people?
For a weekend guest couple, yes, though it will feel close. For nightly sharing, we'd point you to the UK double, which gives 67.5cm each for two. Allow at least 2.6m x 2.8m of room for the UK double before you size up.
What size bedroom do I need for a UK small double Hypnos mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk around the bed and open drawers. In a converted loft with sloping ceilings, also check you'll have headroom on the side you climb out.
What sheets and duvet fit a Hypnos Pillowtop Select small double?
Look for fitted sheets sold as small double or 4ft, and choose deep-pocket ones, because this mattress is 29cm deep with a pillow top. A standard double duvet covers the 4ft width comfortably, with a little overhang on each side.
How much wider is a UK small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length. So taller sleepers gain no extra legroom by moving up, but anyone who sprawls sideways will notice the difference straight away.
Will a 4ft Hypnos mattress fit my existing double bed frame?
Only if the frame is built for a 4ft small double. A standard double frame is made for a mattress 15cm wider, so a UK small double would leave a gap and slide around. Measure the inside of the frame first, then compare the retailers listed on this page.
