Assessed from Mlily's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main reasons to pick this one are the adjustable-bed compatibility and the ortho-firm build. The 1000 pocket springs sit at the core, which means support that responds to each part of your body separately rather than as one rigid slab. Above them, quilted gel memory foam contours to your shape while the cooling gel is there to take the edge off the heat that plain memory foam can trap. A Flex Support Border runs corner to corner, so you can sleep closer to the edge without that rolling-off feeling. The base layer is a firmer Flex Support Foam, in keeping with its orthopaedic design. The size range is limited, but for smaller frames it's sensibly priced from £440.83.
Key Features & what's inside
- 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.

Who's it NOT for?
This is an orthopaedic build, so if you prefer a soft, sink-in feel, it will likely feel too firm, particularly for lightweight side sleepers. It's also only made in Small Single, Single and Small Double, so couples wanting a standard Double or King will need to look elsewhere.
Mlily Gel Profile Ortho Pocket 1000 Adjustable Bed Mattress
Is the Mlily Gel Profile Ortho Pocket 1000 suitable for an adjustable bed?
Yes, it's designed for adjustable bases. The 1000 pocket springs and foam layers are built to flex with the profile of the bed rather than resisting it, which is why Mlily sells it specifically as an adjustable bed mattress.
How firm is the Mlily Ortho Gel 1000 mattress?
Mlily doesn't publish a firmness rating for this model, but it's built as an orthopaedic mattress with firm ortho pocket springs and a firmer support foam base. Expect it to sit at the firmer end of the spectrum rather than plush.
What sizes does the Mlily Gel Profile Ortho Pocket 1000 come in?
It's available in UK Small Single, UK Single and UK Small Double, priced from £440.83. There's no standard Double or King option, which reflects its focus on adjustable beds, where smaller and split sizes are common.
Does the Mlily Gel Profile Ortho Pocket 1000 have a guarantee?
Yes, Mlily lists a 5-year guarantee on its own site. The mattress is also FIRA tested. No sleep trial is stated on the brand page, so check terms with your retailer before buying.
Does the gel memory foam in this mattress sleep cool?
The top layer is memory foam infused with cooling gel, which is designed to draw heat away from your body as the foam moulds to you. It should run cooler than plain memory foam, although very hot sleepers may still prefer a spring-only surface.
