Layer Details
Memory foam layer
A 2cm memory foam layer that gently contours to your shape. It eases pressure points a little, though at this depth the contouring is light, which fits the firm feel.
Comfort support foam
A 3.5cm layer of high density comfort foam that gives adaptive support. It sits between the memory foam and the springs, so you get a steadier feel underneath the top layer.
Pocket spring core
Several rows of small diameter pocket springs, each in its own cloth sleeve, with 2000 springs in total. Because each spring works on its own, the mattress responds to your shape and movement rather than moving as one piece.
Flex support foam base
A foam base layer that provides corner to corner support. It gives the springs a stable platform and helps the whole mattress feel even across its surface.

Key benefits
- Proper space for two: At 75cm each for two people sharing, you can both change position without a negotiation, which is the main reason couples upgrade to a UK king.
- Pocket springs help with different schedules: The pocket sprung design responds to each sleeper independently, which means an early alarm on one side is less likely to wake the other.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, so feet stay on the mattress rather than hanging off the end.
- Fits a typical master bedroom: We suggest at least 2.7m x 2.9m for a UK king, which most master bedrooms manage even after wardrobes go in.
- Affordable route into the size: This model sits towards the cheaper end for a pocket sprung and memory foam design, which makes the jump up to a king easier to justify.
This size suits you if...
You share the bed every night and have outgrown a double, or one of you keeps different hours and you want movement on one side to disturb the other less. It also suits couples where one partner is tall, since the 200cm length adds headroom a 190cm double can't. If the dog has a permanent spot on the bed, the extra width absorbs that too.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone and don't need the width. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m of room space.

FAQ's
Is the Mlily Lite Synergy in a UK king big enough for a couple?
Yes, comfortably for most. The UK king gives 75cm each for two people sharing, which is 7.5cm more each than the UK double provides. If one of you sprawls, or you regularly share with a pet or a small child, the UK super king offers 90cm each, though it demands a bigger room.
What room size do I need for the Mlily Lite Synergy UK king?
We suggest at least 2.7m x 2.9m, which allows walking space around the bed and room for doors and drawers to open. That's our guidance rather than Mlily's. New build master bedrooms often look generous empty but shrink once fitted wardrobes go in, so measure the usable floor, not the room on the plan.
Is the UK king long enough if my partner is over six foot?
It helps. At 200cm, the UK king is 10cm longer than the UK double, which is often the difference between feet on the mattress and feet over the edge. For anyone approaching 6ft or beyond, the length is arguably the bigger upgrade than the width. The UK super king is the same length, so sizing up buys width only.
Will I feel my partner moving on the Mlily Lite Synergy king?
Less than on a smaller size. The pocket sprung construction compresses under each sleeper individually rather than as one surface, and the 75cm of width each means you're rarely lying on the same springs. If one of you gets up hours before the other, that combination reduces the chance of a full wake-up. Mlily publishes limited construction detail beyond this, so check the retailer listing for specifics.
Should I choose the double or the king in this mattress?
If the room takes it, the UK king. It's 15cm wider and 10cm longer than the UK double, and the UK double gives 67.5cm each for two sharing, which many couples find tight. Choose the UK double only if your room falls short of 2.7m x 2.9m, or if the price gap on the retailers listed here stretches your budget.
