Layer Details
- Memory foam layer. A memory foam layer sits at the top, which means the surface moulds gently to your body as it warms. This is where the pressure relief comes from.
- Pocket springs. Beneath the foam, 1000 pocket springs form the core of the mattress. Each spring is sewn into its own fabric pocket, so it responds to your weight individually and helps keep movement from travelling across the bed.

- Fits where bigger beds can't: At 90cm wide it leaves floor space clear, so a child's room can still hold a wardrobe, a desk and somewhere for the toys.
- Doubles up in a shared room: Two UK singles plus a walkway fit in rooms where a double would swallow the floor, useful for siblings sharing.
- Springs where budget beds often use foam alone: The 1000 pocket springs give the single proper structure, which means it should hold its shape better than a cheap all-foam slab.
- Guest-room sensible: For a spare room that spends most of its life as an office, this size and price point keep the bed a background item rather than a commitment.
- Cheap, plentiful bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're kitting out a child's or teenager's room, furnishing a guest bed that sees occasional use, or you're a single adult in a compact room or first flat where the frame came with the tenancy and the mattress didn't. The low price suits any bed you don't want to spend heavily on, though a lighter sleeper gets the same pressure relief from the memory foam as anyone else.
Consider another size if...
You're an adult who sleeps sprawled, or two of you will ever share the bed. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Is the Everyday Arthur UK single good for a child's bed?
Yes, within reason. The memory foam layer cushions shoulders and hips while the 1000 pocket springs provide the support underneath, and the 90 x 190cm footprint is the standard for children's frames. It's a budget mattress, so expect a basic finish, but for a growing child who'll outlast it anyway, that trade-off is reasonable.
Will the UK single Everyday Arthur fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. The catch is depth: Arthur Sleep doesn't publish a depth for this mattress, and raised frames usually need the mattress to sit below the guard rail. Check your frame's maximum mattress depth and confirm the measurement with the retailer before ordering.
Can two Everyday Arthur singles work in a shared children's room?
Often better than one bigger bed. Two UK singles at 90cm wide each can sit against opposite walls with a walkway between, giving each child their own space. The pocket springs help here too: each spring moves independently, so one restless sleeper is less likely to feel like the whole room is bouncing.
How much space does a UK single mattress need in a small room?
Allow at least 2.1m x 2.8m of floor space, which is our suggested minimum rather than the brand's. That leaves room to walk alongside the bed and open a wardrobe door. In a loft conversion, the 90cm width also makes it easier to tuck the bed under the slope where headroom is tight.
Is a single big enough for an adult, or should I size up?
For one average-sized adult who sleeps fairly still, a UK single works, and it's the obvious choice in a student room or box room. If you turn a lot or simply want spread-out space, the Everyday Arthur also comes in a UK double, 45cm wider and the same length. Compare the retailers listed on this page for current prices.
