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.
Layer details from mattressonline.co.uk product page, September 2026.
- Real space for one: At 30cm wider than the UK single, it gives a solo sleeper genuine room to sprawl without demanding a bigger bedroom.
- Fits compact rooms: Being 15cm narrower than the UK double, it slots into box rooms and studio flats where every centimetre of walking space matters.
- Pressure relief where you lie: The memory foam layer cushions hips and shoulders, which means a solo sleeper can settle anywhere across the 120cm width in comfort.
- Quiet support for occasional sharing: The 1000 pocket springs move independently, so on nights a partner or guest shares, movement on one side transfers less to the other.
- Easy bedding to find: 4ft is a standard UK size, so small double fitted sheets and frames are stocked almost everywhere.
This size suits you if...
You're a solo adult who has outgrown a single and wants space to stretch, but your room can't take a full double. It also suits a teenager moving up from a single in a bedroom that needs its floor space, or a guest room where couples stay the odd weekend rather than every night.
Consider another size if...
You share the bed every night and want proper space for two. We'd recommend the UK double instead: it's 15cm wider, giving 67.5cm each for two sharing, and needs a room of at least 2.6m x 2.8m.

Is the Memory Zone 1000 Pocket small double big enough for two adults?
For occasional nights, yes. The pocket springs adapt to each sleeper independently, so a visiting couple will sleep reasonably undisturbed. For every night, 120cm is a squeeze for two adults; the UK double adds 15cm of width and gives 67.5cm each, which makes a real difference over months of sharing.
What room size do I need for a small double Memory Zone 1000 Pocket?
We suggest a room of at least 2.4m x 2.8m for a UK small double. That allows walking space around the bed and room for a door to open, though check your own layout: radiators, built-in wardrobes and sloped ceilings in loft rooms can all eat into the usable floor.
Should I buy the Memory Zone 1000 Pocket in a small double or a double?
It comes down to who sleeps in it and how much floor you can spare. Sleeping alone in a compact room, the UK small double is the sensible pick. Sharing nightly, go for the UK double: it's 15cm wider, the same length, and needs a room of at least 2.6m x 2.8m.
Is the small double Memory Zone 1000 Pocket good for a teenager?
It suits a teenager who has outgrown a single, provided the room keeps enough floor space; the UK small double is 30cm wider than the UK single but the same length. The medium firm feel with a memory foam top works well for lighter bodies, though a heavier person may want deeper support layers.
Will the Memory Zone 1000 Pocket small double fit in a loft conversion?
Often, yes. At 120cm wide it can leave standing room beside the bed where a UK double would run into the sloped ceiling, and the 20cm profile keeps the overall height modest. Measure where the ceiling meets usable head height before you buy, then compare the retailers listed on this page.
