At 27cm deep with a 2,800 spring count in the king size era of construction, the MLILY Glacier 2800 sits at a fair price for a cooling hybrid with so much going on inside. It's hypoallergenic, vegan friendly and available in UK Double, King and Super King. If you sleep warm but like a cushioned, slightly cradling surface, this one deserves a look.

Why should you choose this mattress?
Cooling is the headline here. The quilted sleep surface and the M-Luxe Cool Gel Memory Foam beneath it are both designed to draw heat away from your body, which means you should feel that gentle memory foam hug without waking up clammy. Underneath, mini pocket springs and full-size pocket springs work together, and because each spring moves independently the mattress can respond to your shoulders and hips separately rather than as one flat surface. The medium firm feel suits most back and side sleepers, although very lightweight side sleepers may find it a touch firm through the shoulder. Certifications for fire resistance, hypoallergenic materials and vegan-friendly construction round it out.
Key features & layer details
Gel Infused Quilted Sleep Surface
A quilted top layer of M-Luxe Gel Memory Foam that cushions your pressure points, which means less strain on hips and shoulders. The gel infusion draws heat away from your body as you sleep.
M-Luxe Cool Gel Memory Foam
A second layer of cool gel memory foam that gently moulds to your body shape for full-body support. It continues the heat-drawing work of the surface above, keeping things fresher through the night.
Reflex foam and mini pocket springs
A layer of mini pocket springs sandwiched between breathable reflex foam, which moulds to your body for a more personalised feel. The mini springs add responsiveness that foam alone can't match.
Full-size pocket springs
Full-size pocket springs sit in individual fabric pockets so each one moves independently. In practice, that means targeted support for each part of your body and less motion transfer to a partner.
High-Density Support Foam Base Layer
A deep base of supportive Flex Foam that promotes healthy spinal alignment. It anchors the whole mattress and provides full-body tension relief.

Best suited for?
Warm sleepers
The gel infused quilted surface and cool gel memory foam beneath are both designed to draw heat away, so you get the memory foam hug without feeling clammy.
Couples
Full-size pocket springs sit in individual fabric pockets and move independently, which means less motion transfer when your partner shifts or gets up in the night.
Back sleepers
A medium firm feel with memory foam moulding to your shape and a deep supportive foam base gives steady, full-body support while you lie flat.
Allergy sufferers
Hypoallergenic materials are certified in this mattress, which makes it a sensible pick if you want bedding that has been made with allergens in mind.
Side sleepers
Independently moving springs respond to your shoulders and hips separately, and the cushioning gel memory foam top layer eases pressure points, though very lightweight sleepers may find it firm.
If you prefer a soft, sink-in feel, the medium firm rating will likely feel too solid. If you prefer a traditional, springy sprung-only mattress, you may find the memory foam layers a little slow to respond. There's also no single size, so solo sleepers wanting a UK Single will need to look elsewhere.
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 Glacier 2800 good for hot sleepers?
It's built with hot sleepers in mind. Both the quilted sleep surface and the M-Luxe Cool Gel Memory Foam layer are designed to draw heat away from your body, so you get memory foam comfort with less of the warmth that foam mattresses are known for.
How firm is the MLILY Glacier 2800?
It's rated medium firm. That suits most back and side sleepers, offering a supportive base with a cushioned, contouring top, although lightweight side sleepers may find it slightly firm at the shoulder.
What sizes does the MLILY Glacier 2800 come in?
It's available in UK Double, UK King and UK Super King. There's no single size, which is a shame for solo sleepers or children's rooms.
Does the MLILY Glacier 2800 come with a guarantee or trial?
MattressNextDay lists a 5-year guarantee alongside free next day delivery, although some addresses may incur a small fee. These are the retailer's stated terms, so check them at the point of purchase. No trial period is mentioned on that listing.
How deep is the MLILY Glacier 2800 mattress?
It's 27cm deep, made up of five layers including gel memory foam, reflex foam, mini pocket springs, full-size pocket springs and a high-density foam base. Standard deep fitted sheets should fit comfortably.
