Inside the Hypnos Honley Extra Firm sits 1000 ReActivePro™ pocket springs topped with wool, cotton blends and recycled eOlus™ fibres, which means you get natural temperature regulation without any memory foam sink. It's 30cm deep and comes in eight sizes, from UK Single up to Emperor, plus EU sizes. Extra firm is a specialist feel, so this suits back and front sleepers who like a solid base rather than anyone hoping for a plush, cradling surface. MattressOnline offers a 100-night trial and a 10-year guarantee.

Why should you choose this mattress?
Choose the Honley if firmness is the point. The extra firm rating comes from the springs and fibre layers rather than dense foam, so it should feel supportive without sleeping hot. The wool fillings are Responsible Wool Standard certified and naturally breathable, which means less overnight clamminess than synthetic-heavy builds. Three outer rows of firmer gauge springs stiffen the edges, useful if you sit on the bed to dress or sleep near the side. Hypnos is a National Bed Federation Approved Brand, and the retailer listing shows a 10-year guarantee. It's a real investment, but the natural fillings and spring construction are the sort that justify it, provided extra firm is truly what your back needs.
Key features & 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.

Best suited for?
Back sleepers
The extra firm feel comes from springs and fibre layers rather than foam, giving a solid, supportive base that keeps you lying on top of the mattress.
Front sleepers
A firm spring base with no memory foam sink means your body stays level on the surface instead of dipping into it.
Couples
Each of the 1000 pocket springs sits in its own fabric pocket, which means less movement carries across the bed when your partner shifts.
Warm sleepers
Breathable wool, a viscose cover and cotton blend layers that wick moisture away help keep the surface fresher without any heat-trapping foam.
Eco-conscious buyers
The wool fillings are Responsible Wool Standard certified, and the eOlus™ fibres in the comfort layers are made from recycled materials.
This is a specialist feel. If you're a side sleeper, particularly a lighter one, extra firm will likely put too much pressure on your shoulders and hips. Anyone who loves a soft, sink-in surface should look elsewhere. And the detailed specification lists it as single-sided, so you won't be able to flip it.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Hypnos Honley mattress?
It's rated Extra Firm, the firmest end of the scale. That firmness comes from 1000 ReActivePro™ pocket springs and slightly firmer eOlus™ fibre layers, softened a little by wool and soft white fibres on top. It suits back and front sleepers who want solid support, rather than side sleepers needing pressure relief.
Does the Hypnos Honley come with a trial period?
MattressOnline offers a 100-night trial. That's the retailer's own term rather than a Hypnos guarantee, so check the conditions with whichever shop you buy from.
Can you flip the Hypnos Honley mattress?
The retailer's detailed specification lists it as single-sided, so it isn't designed to be flipped. You should still rotate it regularly to help the natural fillings settle evenly.
What is the Hypnos Honley made of?
It combines a breathable viscose cover, Responsible Wool Standard certified wool, two cotton and polyester blend layers, recycled eOlus™ fibres and soft white synthetic fibres, all over 1000 pocket springs. The mattress is 30cm deep and conforms to BS7177: 2008 for fire resistance.
How much does the Hypnos Honley cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It comes in eight sizes, including UK Single, Double, King, Super King, Emperor and EU Double and King. MattressOnline lists free delivery to most locations, with mattress recycling and room of choice delivery available for an extra charge.
