Layer Details
Memory foam
A 70mm layer of memory foam sits just under the soft stretch fabric cover and is designed to contour to your body shape. You get a cushioned, shaped feel at the surface, which suits a medium feel.
Open coil spring system
Rows of springs linked together with spiral helical wires give medium support underneath the foam. It makes a simple, supportive base, though open coils are a more basic build than individually wrapped springs.

Key benefits
- Real space for one: At 30cm wider than a UK single, it lets a solo adult roll over and stretch out without teetering near the edge.
- Fits rooms a double won't: Being 15cm narrower than a UK double can be the difference between a door that clears the bed and one that doesn't.
- Sensible for guest rooms: A couple can share it for a weekend visit comfortably enough, so it suits spare rooms where nobody sleeps nightly.
- Standard 4ft sizing: Small double is a recognised UK size, so frames, fitted sheets and mattress protectors are easy to find on the high street.
- Same length as a double: You give up width but no length: at 190cm it matches the UK single and UK double, so taller sleepers lose nothing.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't spare the floor space a full double demands, your box room, studio or loft conversion makes every centimetre of width count, or you're furnishing a guest room where couples stay occasionally rather than every night.
Consider another size if...
You share the bed most nights, or your room comfortably clears our suggested minimum with space to spare. We'd recommend the UK double of the Highgrove Stratus instead, which adds 15cm of width at the same length.

FAQ's
What size room do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a small double, which leaves room to walk around the bed and open drawers or a wardrobe. That figure is our own guidance rather than Highgrove's. In a loft conversion or box room, measure where the ceiling slopes and where the door swings before you commit.
Is the Highgrove Stratus in a UK small double big enough for one adult?
Yes, generously so. At 120cm wide it gives a solo sleeper 30cm more width than a UK single, which is enough to change position freely without meeting the edge. It's a sensible step up for a teenager who has outgrown a single, provided the room can absorb the extra footprint.
Should I choose the Highgrove Stratus in a UK small double or a UK king?
They serve different situations. The UK small double is 30cm narrower and 10cm shorter than the UK king, so it suits solo sleepers and compact rooms, while the UK king suits couples with space to spare. If two of you will share the bed every night, the UK small double will feel tight.
What are the exact dimensions of the small double Highgrove Stratus?
It measures 120 x 190cm, or 4ft x 6ft 3in. The length matches the UK single and UK double, so you only trade width, and standard small double fitted sheets will fit. Most people pair it with a regular double duvet, which drapes nicely over the slightly narrower base.
Where can I buy the Highgrove Stratus in a UK small double?
Compare the retailers listed on this page, where prices are updated as retailers change them. Because Highgrove doesn't publish full construction or firmness details for this mattress, it's sensible to read the retailer's own listing before ordering, particularly if a specific feel matters to you.
