Layer Details
- Cover. A soft viscose cover that's naturally breathable, which means the sleep surface feels a little fresher against your skin. It's the first line of temperature control before you reach the fillings.
- Wool. Layers of wool sit just beneath the cover, giving cushioned comfort with natural insulation. Wool regulates temperature in both directions, so it helps in warm summers as well as cold winters.
- Cotton and Polyester Blend. Two layers of a cotton and polyester blend increase airflow through the mattress. They also wick moisture away from your body, which matters if you tend to sleep warm.
- eOlus™ Fibres. These fibres are made from recycled materials and spun into a slightly firmer, cushioning layer. They add to the extra firm feel while giving the mattress a sustainability credential.
- Soft White Fibres. Soft synthetic fillings bring a cosier feel to balance the firmness beneath. They're durable and resilient, so the comfort layer should hold its shape over time.
- Pocket Springs. 1000 ReActivePro™ springs, each in its own fabric pocket, respond to your body individually and reduce partner disturbance. Three outer rows of firmer gauge springs increase edge stability, so you can use the full width of the bed.

- 90cm each, every night: Two people sharing get 90cm apiece, which means a fidgeting partner is simply too far away to wake you.
- Extra firm with room to spread: The solid, no-sink surface stays consistent across the full 180cm width, so back and front sleepers can stretch out anywhere on it.
- Firmer edges you can actually use: Three outer rows of firmer gauge springs stiffen the sides, useful at this width where sleepers often drift towards the edge.
- Space for the whole household: Children or a large dog climbing in at 3am is far easier to absorb when the bed is 6ft x 6ft 6in.
- Cool across a big surface: Wool and cotton blend fillings breathe naturally, so even a bed this large with several bodies in it shouldn't turn clammy.
This size suits you if...
You share every night and want distance from a restless partner, your children or pets treat your bed as theirs and you'd rather have space than a nightly negotiation, or you have a large master bedroom where a smaller bed would look lost. You'll also need to like a properly firm surface: this size gives you room, the Honley itself gives no softness.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you sleep alone. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is the Hypnos Honley super king good for a restless partner?
Yes, arguably more than any comfort layer would be. The 1000 pocket springs respond individually to reduce movement transfer, and the UK super king adds 90cm of width per sleeper on top. Between the two, a partner who turns all night is both cushioned and, more usefully, at a distance.
Should I get the Hypnos Honley in a UK king or a UK super king?
If your room allows it, the UK super king. It's 30cm wider than the UK king and the same length, and on an extra firm mattress where you won't sink into a cradled position, spreading out sideways matters more. The UK king suits rooms of at least 2.7m x 2.9m; the UK super king needs 3m x 2.9m.
Is the Honley super king big enough for a family sharing with children?
It's the best mainstream option for it. At 180 x 200cm there's realistic room for a child between two adults, and the extra firm surface means a small visitor doesn't roll into a dip beside you. It won't feel spacious every night with three aboard, but nobody ends up clinging to an edge.
Can you sleep near the edge of the Hypnos Honley super king?
Yes. Three outer rows of firmer gauge springs support the perimeter, so the sides don't give way when you sit or sleep close to them. That matters at this width, because couples sharing a UK super king naturally spread towards the edges rather than meeting in the middle.
Will the Hypnos Honley super king suit a large dog joining at night?
Better than most sizes would. A big dog at the foot or along one side still leaves two adults with usable space on a 6ft wide bed, and the durable wool and fibre comfort layers are the resilient sort that hold their shape. Check the prices shown on this page, as retailers update them regularly.
