For the highest standards of quality and safety
Discover the blissful comfort of the Hypnos Cawthorne Luxury Mattress, handcrafted for ultimate indulgence.
Support system
Experience the responsive support of 1400 ReActive™ springs as they adapt to your movement through the night. Each spring is encased in a fabric pocket to encourage independent movement, tailored to you.
The outer rows of the springs are firmer to create edge to edge support. This means you can sleep undisturbed by a ‘roll off’ sensation.
Reinforcing the support of the mattress further is a durable eOlus™ dual density pad. Made from recycled materials, this sustainable layer offers a firmer feel that helps to equally distribute weight across the spring system.
Sumptuous comfort
Enjoy temperature regulating bliss with a blended layer of wool and polyester fibres. Both these fibres are plush for ultimate comfort, with breathable properties to increase airflow through the mattress. This helps to dispel heat and moisture. Wool is also inherently insulating, trapping heat in colder weather to keep you at the perfect temperature year-round.
An additional blended layer of rebound cotton and polyester work to wick away moisture from your body, promoting a fresher feel to ease the feel of overheating. This layer is responsive and bouncy, keeping you in a cocoon of comfort.
Balanced firmness
A medium firmness mattress is the perfect choice for most types of sleepers. It provides a balanced feel between firm support and gentle comfort. It is also a great compromise when sharing the bed with a partner when you have different firmness preferences.
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.
