Layer Details
Knitted cover
A soft knitted cover that adds a cosy, warm finish to the sleep surface. The knit construction is breathable, which helps air move through the top of the mattress.
Luna Fusion Cool Memory Foam
A 2cm layer of Luna's Fusion Cool Memory Foam with an open cell structure, which means air moves through it and heat disperses rather than building up. It moulds around your body to ease pressure, giving a cooler feel than standard memory foam.
Reflex Foam
Two layers of reflex foam sit beneath the memory foam, adding cushioning that moulds to your shape. This helps keep your spine aligned as you settle in.
Pocket Springs
1,000 individual springs, each encased in its own cloth pocket, respond to movement separately. That means support is distributed to each part of your body rather than the whole surface moving as one.

Key benefits
- Real space for one: The UK small double is 30cm wider than the UK single, which means a solo adult can starfish freely without needing a bigger room.
- Fits compact bedrooms: At 15cm narrower than the UK double, this size squeezes a proper adult bed into a box room, loft conversion or studio where a 4ft 6in frame would dominate.
- Independent springs, less shared surface: The 1,000 pocket springs respond to movement separately, useful on a 120cm width where two occasional sharers sleep closer together than they would on a wider bed.
- Light to move upstairs: The 20cm build keeps this size manageable, and it arrives rolled, so getting it into a small second bedroom or up a loft staircase is simpler than with a bulkier hybrid.
- Easy bedding and frames: 4ft is a standard UK size, so small double fitted sheets and frames are straightforward to find, and a standard double duvet works fine on top.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're kitting out a guest room where couples stay occasionally rather than nightly, or you're downsizing and the bed has to fit the new room. It also suits a teenager who needs more width without giving up floor space.
Consider another size if...
You share the bed every night, because 120cm is snug for two adults long term, especially with a medium that owners say can feel a touch firm when you're pressed together. We'd recommend the UK double instead; allow at least 2.6m x 2.8m of room for it.

FAQ's
Is a small double big enough for a couple on the Luna Memory 1000?
For occasional nights, yes. The pocket springs move independently, so you won't roll into each other as much as on an open coil bed. For every night, 120cm is tight for two adults, and the UK double gives you 15cm more width at the same length, which makes a real difference.
Will the Luna Memory 1000 small double fit in a box room?
Often, yes, and that's the main reason to pick it. The mattress is 120 x 190cm and we suggest allowing at least 2.4m x 2.8m of floor space so you can still open the door and walk round the bed. Measure your room first, including any alcoves or radiators that eat into the usable width.
What size sheets fit the Luna Memory 1000 in a UK small double?
You need small double (4ft) fitted sheets, which are widely stocked because 4ft is a standard UK size. A regular double duvet works well on top, giving a little overhang on each side. The mattress is 20cm deep, so standard-depth fitted sheets will tuck under without straining.
Is the small double good for a single adult who wants more space?
Yes, that's its strongest use. The UK small double is 30cm wider than the UK single, so you can spread out or change position freely, and the medium feel, which some owners describe as slightly firmer, suits most solo sleepers. You get that extra width without needing the room a UK double demands.
