Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This one suits you if you want the contouring of memory foam without the heat that often comes with it. The bamboo charcoal infusion is there to draw away moisture and keep the surface cooler, and the knitted cover adds breathability on top. The 800 pocket springs adapt to your body shape, which means better spinal alignment than a basic open coil, and the reinforced Aero-Flex border keeps the edges sturdy, so you can sleep right up to the side or sit on it to put shoes on without it sagging. At 22cm deep it's slimmer than some hybrids, but that keeps it lighter to rotate. It's also hypoallergenic and conforms to BS7177: 2008 fire safety standards.
Key Features & what's inside
- Knitted cover. A soft knitted finish that adds cosiness while enhancing airflow. This means the surface stays breathable rather than trapping heat against you.
- Bamboo Charcoal Memory Foam. A 2cm layer infused with bamboo charcoal, which helps regulate temperature and absorb moisture. In practice, that means a cooler feel than standard memory foam.
- Flex comfort foam. A 3cm layer that cushions your body, easing pressure at the shoulders and hips.
- Pocket Springs. 800 springs, each encased in its own cloth pocket so they move independently. This means support adapts to your shape and you feel less of a partner's movement.
- Core Support Foam. A 4cm base layer providing enhanced support beneath the springs, giving the mattress a stable foundation.
- Aero-Flex Support Border. Reinforced edge support that keeps the sides sturdy. This maximises the usable sleeping surface, so you won't feel a roll-off sensation near the edge.

Who's it NOT for?
If you love a soft, sink-in feel, this is listed as medium and some owners report it firmer still, so it may feel too solid for lightweight side sleepers. At 22cm deep it's slimmer than many hybrids, which won't suit anyone wanting a tall, plush profile.

Is the Mlily Bamboo+ Memory 800 firm or medium?
The product listing describes it as medium, though some customer reviews mention it feels firm or medium-firm. If you're a back or combination sleeper that's likely welcome, although lightweight side sleepers may find it slightly too firm for pressure relief.
Does the Mlily Bamboo+ Memory 800 sleep hot?
It's designed not to. The 2cm bamboo charcoal memory foam layer helps regulate temperature and absorb moisture, and the knitted cover enhances airflow. If you're a hot sleeper who's been put off memory foam before, this construction is a sensible compromise.
Does the Mlily Bamboo+ Memory 800 come with a trial?
Mattress Online, the retailer listing this mattress, offers a 100-night trial and a 5 year guarantee. These are the retailer's own terms rather than Mlily's, so check what applies if you buy elsewhere.

Mattress Online offers free delivery to most locations, covering mainland England and most of Scotland, Wales and Northern Ireland, with next day delivery available. Old mattress removal is offered for £35.00. These are the retailer's own delivery terms.
