Layer Details
Gel Infused Quilted Sleep Surface
A quilted top layer of M-Luxe Gel Memory Foam cushions your pressure points while drawing heat away from your body. You'll feel gentle cushioning without the surface warming up overnight.
M-Luxe Cool Gel Memory Foam
This layer gently moulds to your body shape for full-body support and comfort. The gel infusion continues pulling heat away, keeping things fresh rather than clammy.
Responsive Reflex Foam
Reflex foam contours to your shape while keeping the mattress feeling firm. It adds gentle cushioning without letting you sink too far.
Pocket Springs
Full-size pocket springs adjust individually to your movements and weight distribution, which means orthopaedic support exactly where your body needs it. A layer of mini pocket springs sits alongside, refining that support at an even closer level.
High-Density Support Foam Base Layer
A deep layer of Flex Foam anchors the mattress and promotes healthy spinal alignment. It provides the full-body support and tension relief the layers above build on.

Key benefits
- Distance beats any comfort layer: With 90cm each, a fidgeting partner is simply further away, and the individually adjusting pocket springs keep their movement from travelling across to your side.
- Room for the whole household: When a child pads in at 2am, or the dog treats the bed as routine, 180cm of width means everyone still gets a workable share.
- Firm support across the full width: The 2,800 full-size pocket springs respond to each sleeper's weight separately, so two people of different builds both get consistent orthopaedic support edge to edge.
- Cool at the largest scale: Two bodies plus occasional visitors generate heat, and the gel-infused quilted surface keeps drawing it away rather than letting the bed build up warmth overnight.
- A clear step up from the UK king: The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each, a difference you notice every night.
This size suits you if...
You share the bed every night and want space to sleep undisturbed, your partner is genuinely restless and distance matters more to you than any clever spring layer, or children and pets regularly join you and the bed needs to absorb the extra bodies. Your room should also carry it comfortably: allow at least 3m x 2.9m, with around 3.5m x 3.2m feeling right.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or the bed would dominate the space. We'd recommend the UK super king's sibling, the UK king, instead: allow at least 2.7m x 2.9m for that size.

FAQ's
What size room do I need for the MLILY Summit Ortho 2800 in a super king?
We suggest a minimum of 3m x 2.9m, and around 3.5m x 3.2m feels more comfortable, leaving space to walk around the bed and open drawers. This is our guidance rather than MLILY's. Measure with the door swing and any wardrobes in mind, because at 180 x 200cm this mattress fills a room quickly.
How much space does each person get on a super king MLILY Summit Ortho 2800?
Two people sharing get 90cm each. For comparison, the UK king version of this mattress gives 75cm each, so the UK super king gives 15cm more per person. Combined with pocket springs that adjust to each sleeper individually, that width is what lets a restless partner move without waking you.
Should I choose the MLILY Summit Ortho 2800 in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king; both are the same length at 200cm. If children or pets join you regularly, or one of you moves a lot in the night, the extra width is the better buy. If your room is under 3m x 2.9m, the UK king is the sensible choice.
Is the super king version of this mattress good for couples with children who wander in?
It handles it better than any smaller size. At 6ft wide there is genuinely room for a small visitor without anyone clinging to the edge, and the firm feel means the surface stays stable rather than everyone rolling towards the middle. The gel-infused top also helps when three bodies would otherwise make the bed run warm.
Can I buy the MLILY Summit Ortho 2800 in a super king?
Yes, the UK super king is one of three sizes this mattress comes in, alongside the UK double and UK king. Compare the retailers listed on this page for current pricing; the prices shown here are updated as retailers change them. There is no UK single or small double in this model.
