Layer Details
Pillow top
Generous layers of cotton and Solotex recycled fibres sit on the surface. They give gentle full-body cushioning, so the medium-firm feel is softened where you lie.
6-Turn pocket spring unit
Hypnos' ReActivePro 6-Turn pocket springs form the support layer. They give the mattress its medium-firm base, so your body is held up while the pillow top cushions it.

Key benefits
- Room to spread out alone: The UK small double is 30cm wider than the UK single, which means a solo sleeper can turn over or sprawl without hitting the edge.
- Fits where a double won't: It is 15cm narrower than the UK double, so in a box room or loft conversion that small saving can decide whether the door still opens freely.
- Same length as a double: You give up width, not length: the UK small double matches the UK single and UK double at 190cm.
- Cushioning without sinking: The cotton and Solotex pillow top softens the surface while the pocket springs keep the medium-firm support, which suits a solo back or combination sleeper well.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets fit and a standard double duvet covers it comfortably.
This size suits you if...
You sleep alone and have outgrown a single, your bedroom is too tight for a 4ft 6in frame, or you're furnishing a guest room where couples stay now and then but nobody sleeps every night.
Consider another size if...
You share the bed every night with a partner. We'd recommend the UK double instead, which gives 67.5cm each and needs at least 2.6m x 2.8m.

FAQ's
Is the Hypnos Stellar Superior Pillowtop small double big enough for two?
For occasional stays, yes. At 120 x 190cm, the UK small double works for a couple visiting for a weekend, but it is 15cm narrower than the UK double, and that gap shows up night after night. If you share every night, the UK double gives 67.5cm each and is the more comfortable long-term choice.
What size bedroom do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves room to walk round the bed and open a wardrobe. In a loft conversion with a sloping ceiling, measure the floor where you can stand upright, not the full footprint.
What bedding fits a UK small double pillowtop mattress?
Small double (4ft) fitted sheets fit, paired with a standard double duvet. The Stellar Superior Pillowtop is about 30cm deep, so check the fitted sheet's pocket depth before buying, as shallower sheets may struggle to stay tucked over the pillow top.
Is a UK small double long enough for a tall adult?
The UK small double is 190cm long, the same as the UK single and UK double. If you're tall and your feet already reach the end of a standard bed, the UK king adds 10cm of length, though it needs a room of at least 2.7m x 2.9m.
Should I buy a UK small double or UK single for a teenager?
If the room allows, the UK small double gives a growing teenager 30cm more width than the UK single at the same length, which suits someone who has started to sprawl. If floor space is very tight, the UK single needs at least 2.1m x 2.8m, against 2.4m x 2.8m for the UK small double.
