Choose the Ultra 270 if you sleep in a Super King and want a medium-feel memory foam mattress with a bit more depth than usual. The 27cm build gives the foam layers room to work, which means better contouring for side sleepers and a more settled, planted feel overall. The gel infusion matters if you've been put off memory foam by overheating: it won't make the mattress cold, but it should take the edge off. A medium feel suits most back and side sleepers, although heavier stomach sleepers may want something firmer. At £699 for a Super King, the price is reasonable for a gel memory foam mattress of this depth.
Key Features & what's inside

Who's it NOT for?
This isn't for you if you sleep on anything other than a UK Super King, as that's the only size listed. Fans of a springy, responsive surface may also find memory foam's slower, hugging feel isn't to their taste, and very heavy or firm-preferring sleepers might want more support than a medium offers.
Mlily Ultra 270 Mattress
What firmness is the Mlily Ultra 270 mattress?
It's rated medium. That's the middle of the road, which means it suits most back and side sleepers who want a balance of cushioning and support. If you strongly prefer a very firm surface, or you're a heavier stomach sleeper, a medium may feel slightly too soft.
How deep is the Mlily Ultra 270 mattress?
It's 27cm deep, which is on the generous side for a foam mattress. That extra depth gives the layers more room to contour and support you, and it means the mattress should feel substantial rather than shallow. Do check your fitted sheets can accommodate a 27cm profile.
Does the Mlily Ultra 270 sleep hot?
It uses gel memory foam, which is designed to disperse heat better than standard memory foam. It won't feel actively cool the way some spring hybrids can, but the gel infusion should reduce the warmth memory foam is known for. Very hot sleepers may still prefer a sprung design.
What sizes does the Mlily Ultra 270 come in?
It's currently listed in UK Super King only, through one retailer, at £699. If you need a different size, you'll need to look at another model, as no other options are available for this mattress at present.
