Layer Details
COOLMAX sleep surface
A soft-touch, highly breathable COOLMAX fabric that channels heat and moisture away from your body. It should feel dry and fresh against the skin, which helps if you tend to sleep warm.
Comfort Breathe Fibre
A fibre layer made with extra breathable fibres to keep you cool and comfortable. It adds a soft cushion under the cover while letting air move through.
Mini springs
1000 mini springs that respond to even the smallest movement and improve airflow. You get a responsive, comfortable feel, and the springs help air circulate through the mattress.
Airmesh comfort layer
A 3D honeycomb layer that increases airflow around your body by making use of your natural movement in your sleep. It is there to keep you cooler without relying on foam.
Mirapocket springs
600 Mirapocket pocket springs that adjust to your body and give zoned support to improve spinal alignment. They are the main support layer, so they do most of the work of keeping your back well positioned.
Protective layer
A base layer that spreads the pressure from each spring over the full surface of the mattress. This helps the mattress last longer, though you won't feel it as part of the comfort.

Key benefits
- 90cm each for two people sharing: That is a full single bed's worth of space per person, which means neither of you needs to negotiate the middle ground.
- Distance plus pocket springs for restless nights: The 1600 pocket springs already dampen a partner's movement, and at this width you feel even less of it, simply because they are further away.
- Space when children or pets join in: A child wandering in at 3am, or a large dog who treats the bed as routine, still leaves both adults a usable share of the 180cm width.
- A medium feel across a big surface: The medium firmness settles most sleeping positions, so two people with different preferences can usually both get on with it.
- 30cm wider than the UK king: That extra width is the whole point of sizing up: same 200cm length, noticeably more elbow room.
This size suits you if...
You share the bed most nights and want the most sleeping space a standard UK size offers, your children or pets regularly join you and a UK king has started to feel crowded, or one of you is a genuinely restless sleeper and distance matters more to you than any comfort layer. Your bedroom should comfortably clear our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest for this size, or the bed would be for one person. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m and keeps the same 200cm length.

FAQ's
Is a super king too big for my bedroom?
It might be. We suggest a minimum room of 3m x 2.9m for a UK super king, and that is a genuine minimum rather than a comfortable fit. In a period property or a large master it usually looks in proportion; in an average UK double bedroom it can dominate. Measure before you commit, including door swing.
How much space does each person get on the super king Eco Comfort Airmesh 1600?
90cm each for two people sharing, which is the width of a whole UK single per person. Combined with the pocket springs, which move independently so one sleeper's shifting transfers less to the other, that space makes this the size to pick if a restless partner regularly wakes you.
Is the super king worth it over the UK king for this mattress?
If your room and budget allow, usually yes. The UK super king is 30cm wider than the UK king and the same length, and that width is what you notice when children climb in or a partner fidgets. If your room is under 3m x 2.9m, the UK king is the sensible call.
Will a super king mattress get up the stairs?
At 180 x 200cm this is the trickiest standard size to move. Tight landings, banister turns and narrow doorways all bite harder than they would with a UK king. Measure the awkward points of your route before ordering, and check the retailer's delivery access guidance for this size.
Where can I buy the Eco Comfort Airmesh 1600 in a super king?
