Layer Details
Gel Infused Quilted Sleep Surface
A quilted top layer of M-Luxe Gel Memory Foam cushions your pressure points while drawing heat away from your body. You'll feel gentle cushioning without the surface warming up overnight.
M-Luxe Cool Gel Memory Foam
This layer gently moulds to your body shape for full-body support and comfort. The gel infusion continues pulling heat away, keeping things fresh rather than clammy.
Responsive Reflex Foam
Reflex foam contours to your shape while keeping the mattress feeling firm. It adds gentle cushioning without letting you sink too far.
Pocket Springs
Full-size pocket springs adjust individually to your movements and weight distribution, which means orthopaedic support exactly where your body needs it. A layer of mini pocket springs sits alongside, refining that support at an even closer level.
High-Density Support Foam Base Layer
A deep layer of Flex Foam anchors the mattress and promotes healthy spinal alignment. It provides the full-body support and tension relief the layers above build on.

Key benefits
- Fits the typical UK bedroom: Allow at least 2.6m x 2.8m of floor space and the UK double sits comfortably, with room left for a wardrobe and drawers.
- A firm base for two: The 2,800 pocket springs adjust to each sleeper individually, which means one of you shifting position shouldn't disturb the other across a shared 135cm width.
- Cooler when sharing: Two bodies raise the temperature under one duvet, and the gel-infused quilted surface draws that heat away rather than trapping it.
- Easy to dress and manage: Standard double sheets and a 200 x 200cm duvet are stocked everywhere, and a 135cm mattress is simpler to turn stairs with than a UK king.
- Generous for one: Sleeping solo, 135cm gives you room to spread out, or to share the edge with a dog who claims the same corner every night.
This size suits you if...
You're a couple in a typical UK bedroom and want a firm, supportive mattress without giving the bed the whole room, you're furnishing a guest room that visiting couples will use, or you sleep alone and want more space than a single offers, perhaps with a pet who considers part of the bed theirs.
Consider another size if...
You share the bed nightly and 67.5cm each feels tight, especially if either of you is broad shouldered or a restless sleeper. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, giving 75cm each, and we suggest a room of at least 2.7m x 2.9m for it.

FAQ's
Is the MLILY Summit Ortho 2800 double big enough for a couple?
It works for most couples. At 135cm wide you get 67.5cm each, which is the traditional UK shared standard, and the firm pocket-sprung support keeps movement from travelling across the bed. If either of you sleeps restlessly or you're used to more space, the UK king gives 75cm each.
What room size do I need for the MLILY Summit Ortho 2800 in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves walking space on both sides and room for bedside tables, which matters in a shared room where both of you need to get in and out without a squeeze.
Does the MLILY Summit Ortho 2800 come in sizes smaller than a double?
No. The UK double is the smallest size available, so there's no UK single or small double option. Solo sleepers aren't badly served though: 135 x 190cm gives one person plenty of room to spread out on a firm surface, or to share with a pet.
Will a UK double MLILY Summit Ortho fit up the stairs in an older house?
At 135cm wide it's the most manageable size this mattress comes in, and noticeably easier to angle round a turning staircase or a tight landing than the UK king or UK super king. Measure your narrowest turn before ordering, and check the retailer's own delivery guidance for this size.
