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.

Key benefits
- A firm feel in a one-person footprint: The 1000 ReActivePro™ pocket springs respond to one body without compromise, so a solo back or front sleeper gets the full extra firm support the Honley is built for.
- Fits compact rooms: At 90cm wide it leaves floor space free in box rooms, student flats and loft conversions where a wider bed simply wouldn't go.
- Edge support matters more in a single: Three outer rows of firmer gauge springs stiffen the sides, which means you can sleep close to the edge of a narrow bed without feeling like you'll roll off.
- Natural fillings for one warm sleeper: Wool and cotton blend layers regulate temperature naturally, useful in small rooms that heat up quickly overnight.
- Practical for a spare room: A single keeps a spare room usable as an office or study during the day while still giving guests a properly supportive bed.
This size suits you if...
You sleep alone on your back or front and want a genuinely firm surface, your bedroom is compact and a wider bed would crowd the floor, or you're furnishing a spare room that doubles as an office and need a bed that supports guests without dominating the space.
Consider another size if...
You have the room for something wider and would rather stretch out, or you occasionally share the bed. We'd recommend the UK small double instead: it's 30cm wider than the UK single, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

FAQ's
What are the dimensions of the Hypnos Honley single mattress?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in. We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk around the bed and open drawers or wardrobe doors without squeezing past.
Is the Hypnos Honley single suitable for a child's room?
The size is right, since the UK single is the standard for children's and teenagers' rooms. The feel needs more thought: extra firm is a specialist rating, and lighter bodies press into a mattress less, so it may feel harder still to a child. It's a better match for a heavier teen or adult who wants solid support.
Will the Hypnos Honley single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. Depth is the thing to check: this mattress is 30cm deep, which is taller than many raised frames allow, so measure your frame's maximum mattress height and the safety rail clearance before you buy.
Is an extra firm single a good choice for a guest room?
It can be, with a caveat. A single keeps a spare room flexible, and the firm pocket spring surface with breathable wool fillings suits most back and front sleepers. Guests who sleep on their side, particularly lighter ones, may find extra firm uncomfortable, so consider who actually stays with you.
How much smaller is the UK single than the small double in this mattress?
The UK single is 30cm narrower than the UK small double, and the two are the same length. If your room can take the extra width, the UK small double gives a solo sleeper noticeably more space to spread out; allow at least 2.4m x 2.8m of floor space for it.
