Mlily Ultra 300 Mattress
The Mlily Ultra 300 is a 30cm deep, all-foam mattress with a medium feel, built around gel-infused memory foam that adapts to your body while drawing heat away, which means you get that classic contouring hug with less of the warmth foam is known for.
- Cooling gel & ice yarn cover
- Minimises partner disturbance
- Zoned support for spinal alignment
The Mlily Ultra 300 is an exclusive to Furniture Village, made by Mlily for them, and currently listed in UK Super King only. Five foam layers work down from cushioning comfort to zoned support for shoulders, hips and lower back, and it arrives rolled, doesn't need turning, and comes with a removable ice yarn blend cover. The dry-clean-only cover is a minor hassle, but the hypoallergenic build is a plus for allergy-prone sleepers.

Why should you choose this mattress?
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, the price is a fair ask for a five-layer foam build. Furniture Village lists 7-day delivery, with a paid Premium Delivery Service for mattresses, and offers a 2-year guarantee on it.
Key features & layer details
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.

Best suited for?
Warm sleepers
Cooling gel in the memory foam top layer and the ice yarn blend cover work together to dissipate body heat, so it should sleep cooler.
Couples
The responsive transition foam layer minimises motion transfer, which means a restless partner is far less likely to wake you during the night.
Allergy sufferers
The hypoallergenic build suits sleepers prone to allergies, and the removable ice yarn blend cover is a sensible feature for anyone wanting a cleaner sleep.
Side sleepers
Memory foam with a medium feel contours to shoulders and hips, easing pressure at those points, while the zoned support foam keeps your spine aligned.
Combination sleepers
Five foam layers move from soft cushioning to zoned support, giving balanced, evenly distributed support whether you shift onto your back, side or front.
If you sleep in anything other than a UK Super King, this isn't for you: that's the only size listed. If you prefer a springy, traditional pocket-sprung feel, you may find all-foam a little too sinking, and anyone wanting a machine-washable cover should note this one is dry clean only.
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 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. If you need a smaller size, you'll have to look at a different model.
