Assessed from the specification published by Furniture Village, captured September 2026, and from regular price comparison across our UK retail partners.
If you like the slow, cradling feel of memory foam but worry about overheating, the cooling gel in the top layer and the ice yarn cover are designed to tackle exactly that. The transition layer minimises motion transfer, which means a restless partner is far less likely to wake you, and the zoned support foam encourages natural spinal alignment. At 30cm deep it feels substantial rather than budget. Yes, it's only available in UK Super King, but if that's your size, £749 is a fair ask for a five-layer foam build. Furniture Village lists 7-day delivery, with a Premium Delivery Service at £39 for mattresses, and offers a 2-year guarantee on it.
Key Features & what's inside
- Top layer. Memory foam infused with cooling gel that conforms to your body and relieves pressure, which means contouring comfort at pressure points like hips and shoulders. The gel actively dissipates body heat, so it should sleep cooler than plain memory foam.
- Second layer. Soft comfort foam that gently conforms to your body for an overall cushioned feel. It adds softness without compromising the support underneath.
- Third layer. Responsive transition foam with a stabilising effect for balanced support and even weight distribution. It also minimises motion transfer, which means less disturbance when a partner moves.
- Fourth layer. Support foam that promotes natural spinal alignment. It's zoned, giving targeted support to your shoulders, hips and lower back.
- Foundation layer. High-density support foam forming the base of the mattress. It provides long-lasting support and helps maintain durability and structural integrity.

Who's it NOT for?
If you sleep in anything other than a UK Super King, this isn't for you: that's the only size listed. Fans of a springy, traditional pocket-sprung feel may find all-foam a little too sinking, and anyone wanting a machine-washable cover should note this one is dry clean only.
Mlily Ultra 300 Mattress
Is the Mlily Ultra 300 mattress hot to sleep on?
It's designed not to be. The top layer is memory foam infused with cooling gel that dissipates body heat, and the cover uses ice yarn, a fabric blend intended to feel cool to the touch. That said, all-foam mattresses do tend to run warmer than sprung ones, so very hot sleepers should weigh this up.
What firmness is the Mlily Ultra 300?
It's rated medium. That suits most back and side sleepers, giving cushioning at the shoulders and hips while the zoned support foam keeps your spine aligned. Heavier stomach sleepers who need a very firm surface may want something more supportive.
Do you need to flip the Mlily Ultra 300 mattress?
No. It's a one-sided foam mattress that doesn't require turning, which makes upkeep easier. The cover is removable, but bear in mind it's dry clean only rather than machine washable.
What guarantee comes with the Mlily Ultra 300?
Furniture Village offers a 2-year guarantee on this mattress. Because the Ultra 300 is exclusive to Furniture Village, this is the retailer's own guarantee rather than a manufacturer warranty, so check the terms with them directly before buying.
What sizes does the Mlily Ultra 300 come in?
It's currently listed in one size only, UK Super King, at £749. If you need a smaller size, you'll have to look at a different model.
