Layer Details
- Memory Foam. A memory foam layer that cradles to your unique shape, which means a cushioned, cosy feel as you settle in. It's the layer doing the pressure-relief work.
- Pocket Springs. 1000 individual springs, each encased in its own cloth pocket, adapting to movement to give personalised support across your body. Because the springs move independently, you should feel less disturbance when a partner shifts.

- Fits where space is tight: At 90cm wide, it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or two beds plus a walkway where siblings share.
- Suits raised frames: The 20cm profile sits comfortably within the depth limits most bunk, cabin and mid-sleeper frames set, where a taller mattress could raise a child above the guard rail.
- Grows with a child: The medium firm feel gives lighter bodies enough give to settle in while the 1000 pocket springs keep growing spines properly supported.
- A comfortable guest bed: The memory foam layer cushions hips and shoulders, which means occasional guests get genuine comfort rather than the thin, springy feel spare beds often have.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teen moving up from a toddler bed, you need a mattress for a bunk or mid sleeper where depth is limited, or you're kitting out a spare room or student flat where the frame is provided and space is short. It also suits a solo adult in a compact room, such as a loft conversion with a narrow usable footprint.
Consider another size if...
You're an adult who spreads out in your sleep, or you occasionally share the bed. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Is the Memory Zone 1000 Pocket UK single suitable for a bunk bed?
Yes, in most cases. Its 90 x 190cm footprint matches standard UK bunk, cabin and mid-sleeper frames, and at 20cm deep it sits within the depth limit most raised frames specify so the guard rail still does its job. Check your frame's stated maximum depth before ordering, as a few budget frames allow less.
Is the UK single Memory Zone 1000 Pocket good for a child?
It's a sensible choice. The UK single is the standard children's size, and the medium firm feel balances support for a growing spine with enough memory foam cushioning that lighter bodies still sink in a little. It has room to last through the teenage years too, since a single suits teens and single adults alike.
What room size do I need for a single Memory Zone 1000 Pocket?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves enough clearance to walk around and change bedding without squeezing past furniture. In practice it fits box rooms, loft conversions with a narrow usable strip under the slope, and children's rooms that also hold a desk and wardrobe.
Will the single fit a bed frame from a rental or student flat?
If the frame is a standard UK single, yes: this mattress is 90 x 190cm, the size UK single frames are built around. Measure the frame's internal dimensions first, as some older or European frames are slightly different. An EU single, for example, is longer, and a mattress that's short for its frame will slide about.
What bedding do I need for the Memory Zone 1000 Pocket single?
Standard UK single fitted sheets and a single duvet, which measures 135 x 200cm. Because the single is the most common UK size, bedding for it is the cheapest and easiest to find of any size, useful if you're setting up a guest room or a child's bed and want spare sets on hand.
