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.

- Fits the typical UK bedroom: At 135cm wide, this size sits comfortably in rooms where the UK king would crowd the walking space, and we suggest allowing at least 2.6m x 2.8m.
- Cooling matters more when you share: Two bodies raise the temperature under one duvet, so the gel-infused surface drawing heat away is more useful in a double than in any solo size.
- Pocket springs soften a snug share: With 67.5cm each for two sharing, individually moving springs mean your partner turning over is felt less than it would be on a connected coil design.
- Room for tables both sides: In most doubles-sized rooms this width still leaves space for a bedside table on each side, which a UK king often takes away.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet fit, stocked everywhere at every price, handy if this is going in a guest room.
This size suits you if...
You share the bed every night and your room can't comfortably take a UK king, or you sleep alone and want space to stretch out with the classic couples' width. It also suits a guest room that hosts visiting couples, since the medium firm feel works for most back and side sleepers without asking guests to adapt to anything unusual.
Consider another size if...
You and your partner both want more personal space than 67.5cm each, and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead, which is 15cm wider, 10cm longer and gives 75cm each.

Is the MLILY Glacier 2800 double big enough for two people?
Yes, for most couples. At 135 x 190cm you each get 67.5cm of width, which is the traditional UK sharing standard, though it is a snug one. The full-size pocket springs move independently, so a restless partner disturbs you less than on a connected spring mattress. If either of you is broad-shouldered or over 6ft, consider the UK king.
What room size do I need for the MLILY Glacier 2800 in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves room to walk round the bed and, in most layouts, keep a bedside table on each side. These are our own guidelines rather than MLILY's, so measure your space including door swing before ordering.
Should I get the MLILY Glacier 2800 in a double or a king?
It comes down to your room and how much space you each want. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits rooms where the UK king would dominate. If your room meets our suggested 2.7m x 2.9m for the UK king and you value the extra 7.5cm each, size up.
Will a double mattress get up the stairs in an older house?
MLILY doesn't publish handling guidance for this size, but a 135cm-wide, 27cm-deep hybrid is a two-person job on a turning staircase in an older terrace or a tight new build landing. Measure your stairwell, banister clearance and any low ceilings before delivery day, and check the retailer's delivery terms via the listings on this page.
How does the double compare on price with other sizes?
The UK double is normally the cheapest of the three sizes this mattress comes in, since it uses less material than the UK king or UK super king. Prices move with retailer promotions, so rather than quoting a figure that dates quickly, compare the live prices shown on this page, which update as retailers change them.
