Layer Details
- Mlily Quilted Gel Memory Foam. A 2 cm layer of Mlily memory foam infused with cooling gel and quilted into the surface, which means it moulds to your natural contours while the gel works against heat build-up. It's the first thing you'll feel when you lie down.
- Flex Support Foam. A 4 cm layer of Flex Comfort Foam that adapts further to your body, creating a slightly more cushioned, supportive feel between you and the springs.
- Pocket Springs. 1000 firm ortho pocket springs form the 16 cm core of the mattress. Each spring moves on its own, which means support that adjusts to your shape and less disturbance when a partner moves.
- Flex Support Border. A supportive border running corner to corner, relieving the natural pressure of body weight. In practice it firms up the edges, so the usable sleep surface stretches right to the sides.
- Flex Support Foam. A 3 cm base layer of custom Flex Support Foam that adds an extra level of support underneath the springs. It's firmer here, as you'd expect from an ortho mattress.
- catalogue_correction: note. Ignore this entry if your system requires exactly five layers; see flags for the naming discrepancy.
Layer details from mlily.uk product page, September 2026.
- Room to spread out alone: At 120cm across you get generous solo space, which means you can change position freely without the firmer ortho feel ever pushing you towards an edge.
- Edges you can actually use: The Flex Support Border firms up all four sides, so on a 4ft width every centimetre counts as usable sleep surface rather than a soft drop-off.
- Fits rooms a double cannot: We suggest allowing at least 2.4m x 2.8m, which brings box rooms, lofts and small second bedrooms into play where a wider bed would block the walkway.
- Copes with occasional sharing: The 1000 pocket springs move independently, so when a guest or partner shares for a night or two, their movement is less likely to travel across to you.
- Adjustable base, compact footprint: Because the build is designed to flex with adjustable frames, you can have a profiling bed in a room that would never take one in a larger size.
This size suits you if...
You sleep alone most nights, have outgrown a UK single, and want a firmer supportive feel with real room to stretch. Or your bedroom is too tight for a standard double and you'd rather keep floor space than squeeze in a wider frame. It also fits if you're kitting out a guest room or second bedroom where couples stay occasionally rather than nightly.
Consider another size if...
Your room is under our suggested 2.4m x 2.8m, or the bed is for a child who doesn't need the width. We'd recommend the UK single instead, which is 30cm narrower, the same length, and needs a room of around 2.1m x 2.8m.

Is the Mlily Ortho Pocket 1000 small double big enough for a couple?
For occasional nights, yes. The independent pocket springs limit movement transfer and the firm border means neither of you loses width to a soft edge. For every night, though, 120cm is a squeeze for two adults, and this mattress isn't made in a UK double or larger, so nightly sharers should consider a different model.
What size room do I need for the Mlily small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to open the door, walk round the bed and fit basic furniture. It's our own guidance rather than Mlily's, and it's why this size works in box rooms and loft conversions where a UK double, which we'd give at least 2.6m x 2.8m, would dominate.
What are the dimensions of the Mlily Gel Profile Ortho Pocket 1000 in a small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in. That's the standard UK small double footprint, so 4ft frames, adjustable bases and small double fitted sheets will all fit without hunting for anything unusual.
Is the small double the biggest size this Mlily mattress comes in?
Yes. Mlily makes this mattress in UK small single, UK single and UK small double only, so the small double is the largest option. If you want the firmest widest version of this particular build, this is it, and you can compare the retailers listed on this page for the current price.
How much bigger is this mattress in a small double than a single?
The UK small double is 30cm wider than the UK single, and the two are exactly the same length. That extra width is the difference between sleeping in one position all night and genuinely spreading out, which matters on a firmer orthopaedic surface where you sit more on top of the mattress than in it.
