Layer Details
- Bamboo Charcoal Memory Foam. A 2cm top layer with air channels that let air flow through the mattress. The bamboo charcoal also absorbs moisture, which helps regulate temperature through the night.
- Flex Comfort Memory Foam. A 2cm layer of memory foam that cradles to your shape. This is where the cushioned, contouring feel comes from.
- Ortho Comfort Foam. A 3cm layer specifically engineered to ease back and joint pain. It sits between the softer comfort foams and the springs.
- Pocket Springs. 800 Ortho Firm pocket springs, each encased in its own cloth pocket so it moves independently. This means the mattress adapts to your movement and distributes support where your body needs it.
- Core Support Foam. A 4cm base layer of supportive foam that adds extra firmness. It promotes spinal alignment, underpinning the firm feel of the whole mattress.

- Room to share, space to live: At 135 x 190cm, the UK double fits comfortably in rooms where a UK king would crowd out everything else.
- 67.5cm each for two sharing: Two people get 67.5cm of width apiece, which works well here because the firm surface stops you rolling towards each other.
- Pocket springs earn more in a shared bed: The 800 individually pocketed springs move independently, which means your partner's turning is less likely to travel across to your side.
- Fits our suggested minimum for most bedrooms: We suggest a room of at least 2.6m x 2.8m, which most UK second bedrooms and older terraces can manage.
- Easier to get upstairs: At 23cm deep and 4ft 6in wide, this size is more forgiving on turning staircases and tight landings than a UK king.
- Easy to dress: Double sheets and duvets are sold everywhere at every price, useful if you're kitting out a whole home on a budget.
This size suits you if...
You share the bed every night and want firm support without the bed dominating the room, or you sleep alone and like space to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the firm feel copes with a range of sleepers passing through.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a restless sleeper. We'd recommend the UK king instead, which gives 75cm each for two sharing; allow at least 2.7m x 2.9m of room space for it.

Is the Mlily Bamboo+ Ortho Memory 800 UK double big enough for a couple?
Yes, for most couples. The UK double gives 67.5cm each for two people sharing, and the firm surface helps because neither of you sinks into a dip in the middle. Broad-shouldered pairs, or anyone used to sleeping apart, may prefer the UK king, which gives 75cm each.
What size room do I need for the Mlily Bamboo+ Ortho Memory 800 in a UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. This is our guidance rather than Mlily's, so measure your own layout before ordering.
Should I choose the Mlily Bamboo+ Ortho Memory 800 in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king, and the UK king gives 7.5cm more width each for two sharing. If your room comfortably exceeds 2.7m x 2.9m and you both value space, size up. If space or budget is tight, the UK double serves most couples well.
Will I feel my partner moving on this mattress in a double?
Less than you might expect for a shared size. The 800 pocket springs are each encased in their own cloth pocket and compress individually, so movement on one side doesn't ripple across the whole 135cm width the way it can on an open coil double.
Will a double mattress fit up a narrow staircase?
Usually, yes. At 4ft 6in wide and a slightly slimmer 23cm deep, this size is easier to manoeuvre round turning stairs in older terraces or tight new build landings than a UK king would be. Measure any awkward corners first, and check the retailer's delivery details on this page.
