Layer Details
Wool and bamboo foam cover
A quilted cover blending wool with 2cm of Bamboo Memory Foam. It gives the surface a soft, cushioned first feel.
Bamboo Air Memory Foam
A 2cm ventilated memory foam layer that encourages airflow. It helps regulate body temperature while still contouring to you.
Flex Comfort Foam
A 3cm layer of responsive foam that adapts to your body contours. It adds cushioning between the top layers and the springs.
Pocket springs
Individually wrapped, small-diameter pocket springs, 14cm deep and not directly attached to their neighbours. They support each part of your body separately.
Airtech Border
A border with a moulded F-Joint system, designed for even edge-to-edge support and consistent airflow. It helps the whole surface feel usable.
Flex Support Foam base
A custom 4cm foam base that gives the mattress complete support from underneath. It keeps the springs stable above it.

Key benefits
- A single's width each: With 90cm each for two people sharing, you each get the full width of a UK single, which means fewer elbows and knees crossing into your half.
- Less disturbance from a restless partner: The 14cm pocket springs are individually wrapped and not attached to their neighbours, so a partner's movement travels less, and the extra distance helps further.
- Room to use the outer edges: The moulded Airtech Border is designed to support evenly out to the sides, which matters when a child or dog nudges you towards the edge.
- Easier to get upstairs: It arrives vacuum packed, which means a mattress 6ft x 6ft 6in once open is far easier to carry round a tight landing turn than a flat one.
- Airflow for a crowded bed: A ventilated memory foam layer sits beneath the wool and bamboo cover, which should help when extra bodies in the bed add warmth through the night.
This size suits you if...
You share with a partner who tosses and turns, your children or a large dog regularly end up in bed with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or the bed would block a door or wardrobe. We'd recommend the UK king instead, which is 30cm narrower and needs at least 2.7m x 2.9m.

FAQ's
What size bedroom do I need for a Mlily Haluna super king mattress?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable. In a loft conversion, measure where the ceiling slopes, because you'll want the headboard wall and both sides of the bed to have proper standing height.
Is the Mlily Haluna UK super king worth it over the UK king?
If you share with a restless partner or a child, often yes. The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each for two sharing. If space for two adults alone is your aim and the room is tight, the UK king is the sensible choice.
Is a super king big enough for two adults and a child?
It's the most room you'll find in a standard UK size, at 180cm wide. Two adults get 90cm each before a child joins, and the moulded border is designed to support right to the edges, so whoever ends up on the outside isn't perched on a soft rim.
Will a super king mattress in a box fit through my door and up the stairs?
Packed, it should handle tight landing turns well, since it arrives vacuum packed. The bigger check is the room itself: once opened it's 6ft x 6ft 6in, so make sure the bedroom door can still swing open with the bed in place before you order.
What bedding do I need for a Mlily Haluna super king?
You'll need super king sheets and a 260 x 220cm duvet. The mattress is 25cm deep, so choose a fitted sheet with pockets deep enough to tuck well under. Bedding at this size costs more than for a UK king, so factor it in before deciding.
