Silentnight Airmesh 1600 Eco Comfort Super King Mattress
The Silentnight Airmesh 1600 Eco Comfort is a pocket spring mattress with a medium firm feel, which means the springs respond to your body individually rather than moving as one unit, so you should feel less disturbance from a restless partner.

Layer Details
Coolmax cover
A soft, tactile cover made with Coolmax, which is designed to feel cool against the skin. It gives you a smooth, fresh-feeling surface to settle onto.
Comfort Breathe Fibre
A breathable fibre filling with a soft feel. It adds a little cushioning under the cover while letting air move through, so heat is less likely to build up.
1000 mini pocket springs
1,000 mini pocket springs that respond instantly to small movements through the night. This means the surface adjusts as you shift, rather than pushing back in one go.
Airmesh layer
A 3D honeycomb design that uses your body movement to push air around inside the mattress. The aim is better air circulation, which should help you stay fresher as you sleep.
600 Mirapocket springs
600 pocket springs that give deeper support and are designed to improve posture. This is the layer that helps keep your hips and spine in line.
Support pad
A supportive foundation for the layers above. You won't feel it directly, but it gives the springs a stable base to work from.

Key benefits
- Distance beats any comfort layer: With 90cm each for two people sharing, a restless partner is simply further away, and no spring technology matches that.
- Pocket springs, amplified by width: The springs respond individually rather than as one unit, so movement on one side stays there, and the super king's width doubles that isolation.
- Room for night-time visitors: When a child pads in at 3am, or the dog treats your bed as routine, everyone can still find a workable share of 180cm.
- Medium firm across the full width: The medium firm feel keeps hips level for back and stomach sleepers, and stays consistent however far apart you and your partner sleep.
- Full 200cm length: At 6ft x 6ft 6in, taller sleepers get 10cm more length than a UK single or UK double offers, so feet stay on the mattress.
This size suits you if...
You share the bed every night and want the maximum sleeping space a mainstream UK size offers, your partner turns over often enough that a UK king still feels crowded, or your household includes children or pets who treat your bed as partly theirs. It also suits a large master bedroom or period property where a UK king would look a little lost against the wall.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum for this size, or you sleep alone. The UK king would suit you better: it's the same length, 30cm narrower, and we suggest at least 2.7m x 2.9m for it.

FAQ's
What room size do I need for a super king Silentnight Airmesh 1600?
We suggest at least 3m x 2.9m. That leaves walking room down both sides and space for the door to swing, though a room around 3.5m x 3.2m feels more comfortable with bedside tables on both sides. Measure the room and the route to it before ordering, as this is a large single-piece mattress.
Is the super king Airmesh 1600 good for couples with a restless partner?
Yes, and it's arguably the best case for this size. The pocket springs move individually rather than as one unit, so turning over on one side transfers little movement across the bed, and 90cm each for two people sharing adds physical distance on top. The combination does more for disturbed sleep than any single comfort layer could.
Will a super king Airmesh 1600 fit up my stairs?
It's the tightest of the sizes to move, so check tight landing turns, low ceilings and door swings along the route before you buy. A loft conversion master needs extra thought: the slope often decides which wall the bed can sit against, and a 180 x 200cm footprint limits your options. Silentnight doesn't publish a weight, so ask the retailer if that matters.
Is the super king worth it over the king for this mattress?
If your room takes it, usually yes. The UK super king is 30cm wider than the UK king and the same length, and that extra width is what turns a shared bed with children or a large dog from a squeeze into something sustainable. Compare the retailers listed on this page, as prices are updated as retailers change them.
What bedding does the super king size take?
Super king sheets, and we'd suggest a 260 x 220cm duvet. Bedding at this size costs more than UK king equivalents and fewer shops carry it, which is one running cost of the extra width. Factor it in alongside the mattress price rather than discovering it afterwards.
