Layer Details
Memory Foam
Memory foam cradles to your shape, which means a cushioned, contouring feel rather than a springy one. The plush layers mould to your body to encourage correct spinal alignment.
Pocket Springs
2000 standard pocket springs and 1000 mini pocket springs work independently of each other, which means weight is distributed evenly and movement transfers less across the mattress.
Foam Encapsulated Border
A foam wall around the springs firms up the edges. In practice, that means more usable sleep space and less of a roll-off feeling near the sides.

Key benefits
- A gentle feel suited to lighter sleepers: The medium soft memory foam responds readily to lighter body weights, which means children and teens actually sink in enough to feel the contouring.
- Compact footprint for crowded rooms: At 90cm wide it leaves floor space for a desk, wardrobe and toy storage in a child's bedroom, or for two beds with a walkway between them.
- Edge support where it matters for kids: The foam encapsulated border firms up the sides, so a child who drifts towards the edge overnight gets support rather than a roll-off feeling.
- Pressure relief for a solo side sleeper: Memory foam over 3000 pocket springs cushions hips and shoulders, a welcome upgrade in a spare room that guests remember for the right reasons.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager who likes a softer, cradling feel, you need a comfortable guest bed for a spare room that also serves as an office, or you're a lighter solo adult in a compact room, perhaps a first flat or a loft conversion where only a narrow footprint fits under the slope.
Consider another size if...
You want space to spread out as an adult, or a heavier build makes the medium soft feel sink further than is comfortable. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

FAQ's
What size is the Memory Zone 3000 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It's the standard one-person size in the UK, and the smallest of the five sizes this mattress comes in. We suggest allowing at least 2.1m x 2.8m of floor space so you can walk around the bed comfortably.
Will the Memory Zone 3000 UK single fit a bunk bed or mid sleeper?
The width and length match standard bunk frames, but the depth is the thing to check. This mattress is 28cm deep, which is more than many bunk beds allow: guard rails need to sit well above the mattress surface to be safe. Measure your frame's maximum mattress depth before buying, particularly for a top bunk.
Is the Memory Zone 3000 UK single a good choice for a child?
Its medium soft feel works well for lighter bodies, since children sink in enough to feel the memory foam contour rather than lying on top of a firm slab. The foam encapsulated border also supports a child who ends up near the edge. One caution: memory foam can hold warmth, so a very hot sleeper may prefer something breathable.
Should I buy the UK single or the UK small double for a teenager?
If the room allows, the UK small double is a comfortable step up for a growing teen: it's 30cm wider than the UK single and the same length, and we suggest at least 2.4m x 2.8m of floor space for it. In a smaller room, or where the bed shares space with a desk and wardrobe, the UK single keeps things workable.
Where can I buy the Memory Zone 3000 in a UK single?
Compare the retailers listed on this page. The prices shown here are live and updated as retailers change them, so it's worth checking back if you're not ready to buy today. Availability can differ between sizes, so a deal on the UK double won't always apply to the UK single.
