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.

Key benefits
- Room to turn over: Each of you gets 75cm, which is 7.5cm more than on a UK double, so rolling over is less likely to land you on your partner's side.
- Calmer early starts: The full-size pocket springs move independently, so when one of you gets up hours before the other, the movement is kept largely to that side of the bed.
- Length for taller sleepers: At 200cm (6ft 6in) long, the UK king adds 10cm over a UK double, which means a tall partner's feet stay on the mattress rather than over the edge.
- Less stuffy with two: Two bodies give off more warmth than one, and the gel memory foam layers are designed to draw heat away, so a shared UK king should feel a little fresher.
- Manageable room demands: We suggest a bedroom of at least 2.7m x 2.9m, noticeably less than the 3m x 2.9m we'd allow for the UK super king.
This size suits you if...
you share the bed every night and keep waking each other on a UK double, one of you is approaching 6ft and your feet are running out of mattress, or your alarms go off hours apart and you'd like the early riser's movements kept to their own side.
Consider another size if...
your bedroom is smaller than our suggested 2.7m x 2.9m, or you sleep alone most nights. We'd recommend the UK double instead, which needs a room of at least 2.6m x 2.8m.

FAQ's
Is the MLILY Glacier 2800 UK king big enough for two people?
For most couples, yes. The UK king gives each of you 75cm, which is 7.5cm more than the UK double. If you both sprawl, or a child regularly joins you, the UK super king gives 90cm each, although it needs a larger room.
Will I feel my partner moving on the Glacier 2800 king size?
Less than on a narrower bed. The full-size pocket springs each move independently, which limits how far movement travels, and the extra width of the UK king puts a little more distance between you. A restless partner will still be felt occasionally; no mattress removes movement entirely.
Is the MLILY Glacier 2800 UK king long enough for a tall person?
It measures 200cm, or 6ft 6in, which is 10cm longer than a UK double. That extra length is often the real reason people approaching 6ft size up. The UK super king is the same length, so going bigger adds width only, not legroom.
What size bedroom do I need for a Glacier 2800 UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable space to walk around. New build master bedrooms can feel smaller than their plans suggest once wardrobes go in, so measure with furniture in place before you order.
Should I choose the Glacier 2800 in a king or super king?
The UK king suits most couples: it's the same length as the UK super king but 30cm narrower, giving 15cm less each. Choose the UK super king only if you want the most space possible and your room allows at least 3m x 2.9m.
