For the highest standards of quality and safety
The Hypnos Clinton Cotton Deluxe Mattress is expertly handcrafted in the UK. With traceable British wool, responsibly sourced cotton and plush, resilient Solotex™ fibres.
Natural comfort
Generous layers of cotton and wool provide excellent temperature regulation and breathability. Each mattress includes naturally hypoallergenic cotton. It also contains about 4kgs of traceable British Red Tractor wool. Both the wool and cotton are fire-resistant without the use of flame-retardant chemicals.
Resilience
For added bounce-back and lasting shape retention, the Clinton contains Solotex™. This eco-friendly, polyester-based fibre is known for its durability. Designed to promote airflow, Solotex™ offers a cushioning feel. This material can also help the mattress retain its shape over time.
Reactive support
Hypnos offers an innovative take on the traditional pocket spring system with their ReActivePro™ 6-turn system. 1000 pocket springs, each with six active turns, help the mattress react faster and more effectively to your movements. Delivering pressure relief, spinal alignment, and tailored support across the entire sleep surface.
Solid space
Three rows of firmer springs along the perimeter provide complete edge-to-edge support. This Triple Edge Protection™ system adds stability. You can sleep right to the very edge of the mattress, making the most of the full sleep surface. The border is finished with two rows of traditional hand side-stitching for added durability.
The Clinton is single-sided which means you won't have to flip this mattress. You simply need to rotate top to toe seasonally to keep it in great condition.
Responsibly made
The Clinton features pure British wool, traceable to Red Tractor assured farms. So high standards of animal welfare, fair pay for farmers, and environmental care are ensured. At end of life, the mattress is 100% recyclable, supporting a circular, low-impact approach to sustainability.
Highest quality
Hypnos has been handcrafting luxury mattresses here in the UK since 1904. They have been recognised with a Royal Warrant from His Majesty King Charles III for their work. Each Clinton Cotton Deluxe mattress comes backed by a 10 Year Guarantee, a testament to its quality and craftsmanship.
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.
