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.

- Fits compact rooms: At 90cm wide it leaves floor space free, useful where a child's bed competes with a wardrobe, a desk and toy storage.
- Sensible for spare rooms: A single suits a spare room that spends most of its week as an office, keeping the bed's footprint small while still sleeping a guest properly.
- Low-cost way to furnish a provided frame: Student rooms and first flats often come with a single frame but no mattress, and a memory mattress at this price fills that gap without straining a budget.
- Room for two beds: Where siblings share, or a guest room needs two beds rather than one, the 90cm width makes a pair of UK singles plus a walkway workable.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and least expensive of any UK size, which keeps the ongoing costs down too.
This size suits you if...
You're buying for a child's or teenager's room, a guest bed, or yourself as a solo sleeper in a compact space such as a loft room or student flat. It also fits where two beds need to share one room, since the 90cm width leaves space for a walkway between them.
Consider another size if...
You're an adult who moves around a lot at night, or you occasionally share the bed. We'd recommend the UK small double instead, which is 30cm wider than the UK single at the same length.

Will the Highgrove Stratus Memory Mattress in a UK single fit a bunk or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk, cabin and mid sleeper frames, so width and length are fine. Raised frames also have depth limits for guard rails, and Highgrove doesn't publish a depth for this mattress, so check the measurement on the retailer's listing against your frame before ordering.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open a wardrobe or drawers, though in a child's room with a desk and toy storage you may want a little more. Loft rooms with sloped ceilings often suit a single's narrow footprint well.
How much smaller is a UK single than a UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length at 190cm. That 45cm is the difference between a one-person bed and one a couple can share, so if the mattress will ever sleep two, the UK double is the safer buy.
Is the UK single long enough for a tall teenager?
At 190cm, or 6ft 3in, it suits most teens and adults comfortably. Anyone approaching six foot may prefer the extra length of the UK king, which is 10cm longer than the UK single, though that also means a much wider bed and a bigger room to house it.
Can two UK singles fit in one guest room?
Often, yes. Two 90cm-wide beds with a walkway between them need noticeably less width than you might expect, and twin singles are more flexible for guests than one double. Measure your room against two mattress widths plus around 60cm of walking space, and remember bedside tables if you want them.
