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.
Layer details from mattressonline.co.uk product page, September 2026.
- 90cm each for two sharing: With 90cm of width per person, the 800 pocket springs respond to each sleeper individually, so one side's movement barely registers on the other.
- Firm support at full width: The Ortho Comfort layer and core support foam keep the surface consistently firm across all 180cm, which means no soft edges when you spread out.
- Room for the whole household: When children or a large dog treat your bed as theirs, a UK super king still leaves the adults a proper share.
- Distance beats any comfort layer: If your partner genuinely thrashes about, the extra 15cm each over a UK king does more for your sleep than any foam could.
- Airflow across a big surface: The bamboo charcoal top layer's air channels help heat and moisture escape, useful when a firm memory foam hybrid is sleeping three rather than two.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your children or pets regularly join you and everyone still needs their own patch, or your partner is restless enough that separation matters more than any mattress feature. Your bedroom should comfortably clear our suggested 3m x 2.9m minimum, ideally with space to spare.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king, or you mostly sleep alone. We'd recommend the UK king instead, which still gives couples 75cm each and needs at least 2.7m x 2.9m.

Is the Mlily Bamboo+ Ortho Memory 800 super king big enough for co-sleeping with children?
It's the most realistic size for it. At 180 x 200cm, two adults get 90cm each, so a child slotting in overnight still leaves everyone workable room. The firm surface helps here too: it stays level rather than rolling everyone toward the middle. Just don't expect three across every night to feel spacious on any mattress.
Will the Mlily Bamboo+ Ortho Memory 800 super king reduce partner disturbance?
Two things work in its favour. The 800 pocket springs move independently, so motion doesn't travel far, and the sheer width means you're often out of reach of it anyway. Compared with the UK king, you each gain 15cm, which for a genuinely restless partner is the more meaningful upgrade.
What room size do I need for the Mlily Bamboo+ Ortho Memory 800 in super king?
We suggest at least 3m x 2.9m. That leaves walking room on both sides and space for bedside tables without the door catching the bed frame. In a large master or a period property with generous proportions, a UK super king often looks better than a UK king, which can seem undersized against the room.
Is this super king mattress hard to get upstairs?
It's the size most likely to cause trouble on tight landings and stair turns, so measure your route before ordering, including door swings. At 23cm deep it's slimmer than many hybrids, which gives you slightly more flex through awkward corners than a deeper mattress would. Mlily doesn't publish a weight for this size, so check the retailer listing.
Where can I buy the Mlily Bamboo+ Ortho Memory 800 in a UK super king?
