Layer Details
- Knitted cover. A soft knitted finish that adds cosiness while enhancing airflow. This means the surface stays breathable rather than trapping heat against you.
- Bamboo Charcoal Memory Foam. A 2cm layer infused with bamboo charcoal, which helps regulate temperature and absorb moisture. In practice, that means a cooler feel than standard memory foam.
- Flex comfort foam. A 3cm layer that cushions your body, easing pressure at the shoulders and hips.
- Pocket Springs. 800 springs, each encased in its own cloth pocket so they move independently. This means support adapts to your shape and you feel less of a partner's movement.
- Core Support Foam. A 4cm base layer providing enhanced support beneath the springs, giving the mattress a stable foundation.
- Aero-Flex Support Border. Reinforced edge support that keeps the sides sturdy. This maximises the usable sleeping surface, so you won't feel a roll-off sensation near the edge.

- 7.5cm more space each than a double: The UK king gives 75cm per sleeper against 67.5cm in a UK double, which means fewer accidental elbows and easier turning without waking anyone.
- Pocket springs earn more in this width: With 800 springs moving independently across 150cm, one partner getting up at 5am transmits less movement to the other side than a shared-spring design would.
- 200cm length for taller sleepers: The UK king is 10cm longer than the UK double, so anyone approaching 6ft gains room at their feet as well as their side.
- Edge support keeps all 150cm usable: The Aero-Flex border resists that roll-off feeling, so sleeping near the side, or sitting on it, doesn't waste the width you paid for.
- Cooler surface for two bodies: Two sharers generate more heat than one, and the bamboo charcoal memory foam with a knitted cover helps this king stay comfortable through the night.
- 22cm depth stays manageable: A king is heavy to rotate, but this slimmer profile keeps the job realistic for one person, with a bit of effort.
This size suits you if...
You and your partner have outgrown a double and want space to sleep well rather than politely, you keep different hours and need one person's early alarm to disturb the other less, or one of you is around 6ft and keeps finding feet at the end of the bed. It also suits couples whose dog treats the mattress as a third occupant.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you mostly sleep alone. We'd recommend the UK double instead, which needs a smaller room, at least 2.6m x 2.8m by our guidance.

Is a UK king big enough for a couple with different sleep schedules?
Yes, and this mattress helps more than most at the price. The 75cm each of a UK king gives a clear buffer between you, and because each of the 800 springs sits in its own pocket, movement on one side is absorbed rather than passed across. When one of you leaves hours before the other, that matters.
Will the Mlily Bamboo+ Memory 800 UK king fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m comfortable. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the floor you'll actually have left before committing. If it's snug, the UK double needs at least 2.6m x 2.8m.
Is the UK king long enough for someone over 6ft?
At 200cm, the UK king gives you 10cm more length than the UK double, which is often the difference between feet hanging off and not. If height is your main reason for upgrading, the length here does as much work as the width. Sizing up to the UK super king adds width only; the two are the same length.
Can two people use the full width of this mattress?
Yes. The Aero-Flex reinforced border keeps the edges sturdy, so neither of you gets a roll-off feeling sleeping near the side. That makes the full 150cm usable, which is the point of buying a king. It also helps if you sit on the edge to dress, or if getting in and out carefully matters to you.
