At 23cm deep, the Mlily Bamboo+ Ortho Memory 800 is a little slimmer than some hybrids, but the construction is aimed squarely at people who want proper firm support, particularly for backs and joints. The bamboo charcoal memory foam on top has air channels to help with airflow and moisture, a sensible touch given memory foam's reputation for warmth. The price is good value for a pocket sprung hybrid. It's available in UK Single, Double, King and Super King.

Why should you choose this mattress?
Choose this if you sleep best on a firm surface and want memory foam comfort without sinking too deeply. The Ortho Comfort layer is engineered to ease back and joint pain, and the core support foam underneath promotes spinal alignment, so it suits back and front sleepers who need their spine kept level. The 800 pocket springs adapt to movement individually, which means you feel support where you need it rather than a rigid slab. If you're buying on a budget, the starting price makes firm orthopaedic-style support accessible. Mattress Online backs it with a 100-night trial and 5-year guarantee, with conditions worth checking.
Key features & 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.

Best suited for?
Back sleepers
The firm feel and 4cm core support foam promote spinal alignment, which means your back stays level instead of sinking into the mattress.
Front sleepers
Firm support from the Ortho Comfort layer and core foam keeps your middle from dipping, so your spine stays level when lying face down.
Budget buyers
Described as good value for a pocket sprung hybrid, it gives you firm orthopaedic-style support without paying for extras you may not need.
Couples
The 800 pocket springs each sit in their own cloth pocket and move independently, so the mattress adapts to each person's movement.
Heavier sleepers
Five layers, including 800 Ortho Firm pocket springs and a 4cm foam base, give a firm, supportive feel that resists sinking in too deeply.
If you prefer a soft, sink-in feel, this isn't the mattress for you: it's firm throughout, and lightweight side sleepers may find it doesn't give enough at the shoulder and hip. Hot sleepers should also weigh up the memory foam layers, as some owners report heat retention despite the bamboo charcoal top.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Mlily Bamboo+ Ortho Memory 800 firm or soft?
It's firm. The Ortho Firm pocket springs and a 4cm core support foam layer give it a solid, supportive feel, while 4cm of memory foam across the top two layers adds cushioning. It suits people who want firm support, although lightweight side sleepers may find it a little too firm.
Does the Mlily Bamboo+ Ortho Memory 800 come with a trial and guarantee?
Mattress Online offers a 100-night trial and a 5-year guarantee. The trial requires you to buy a mattress protector from Mattress Online, and these terms are the retailer's own, so check conditions before you order.
How deep is the Mlily Bamboo+ Ortho Memory 800 mattress?
It's 23cm deep, made up of five layers: 2cm of bamboo charcoal memory foam, 2cm of flex comfort memory foam, 3cm of ortho comfort foam, 800 pocket springs, and a 4cm core support foam base. Standard fitted sheets should fit without trouble.
Does the Mlily Bamboo+ Ortho Memory 800 sleep hot?
The bamboo charcoal memory foam top layer has air channels for airflow and absorbs moisture to help regulate temperature. That said, some owner reviews mention the memory foam can retain heat, so if you're a very hot sleeper this may not be the best fit.
What sizes does the Mlily Bamboo+ Ortho Memory 800 come in?
It's available in UK Single, Double, King and Super King. Mattress Online offers free delivery to most locations, with next day and weekend options, paid room-of-choice delivery and old mattress removal for an extra charge.
