For the highest standards of quality and safety
Discover the cosy comfort of the Hypnos Cawthorne Deluxe Mattress.
Full body support
Offering relaxing full body support, the core of this mattress features 1000 ReActive™ springs. Exclusive to Hypnos, this spring unit encases each spring into individual fabric pockets. This means the springs can move independently to directly target movement and areas in need of support.
Feel the soothing support of the springs as they encourage spinal alignment to ease aches, helping you wake feeling refreshed.
Comfort layers
Sink into comfort with a layer of Solotex™ fibres. Plush and cosy, this layer keeps you comfortable night after night. Solotex™ fibres are highly breathable, increasing airflow through the mattress to dispel heat and moisture and provide a fresher feel.
The eOlus™ fibre layer provides added cushioning with a slightly firmer feel to keep you feeling supported and comfortable all night long. This layer is made from recycled material for comfort that is kinder to the planet.
The final comfort layer is a dual density polyester fibre pad. One side of this layer is made to provide an extra touch of comfort to sleepers. The other side of the layer is designed to deliver secure support to the spring unit, helping to evenly distribute weight across the mattress.
Balanced firmness
Rated medium, this mattress is a great choice for most sleepers. It is also the ideal compromise when sharing the bed with a partner who prefers a different firmness to you.
Edge support
The ReActive™ spring unit features firmer springs on the outer rows to provide a more stable mattress border. This is further reinforced with a rod edge that is placed along the perimeter of the mattress. So you can enjoy a maximised sleep space and stretch out to the edge without a ‘roll off’ feel.
Easy care
The single-sided design of this mattress means it has a simple and easy care routine. Simply rotate top to toe seasonally to ensure even wear. This will help the mattress retain its shape and increase its longevity.
120 years of expertise
Holding over 120 years of expertise handcrafting luxury mattresses, the experts at Hypnos are skilled in delivering uncompromisable comfort and support.
Complete with a 5 Year Guarantee for ultimate reassurance.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

Started off with medium to firm mattress. Seemed ok in showroom but when sleeping on it I found it a little too firm. Went back to showroom and tried the medium mattress, this time changed manufacturer to Hypnos. Noticeable difference to the better and agreed the exchange. I have now had the mattress for several weeks and find it very comfortable. I am pleased with the Hypnos mattress and would recommend the showroom in Doncaster for their friendly and knowledgeable service .
