The Saunderton Pillow Top mattress is part of the Eco-friendly Hypnos Origins Collection. It includes luxurious fillings of 1 fleece of British wool with sustainably sourced cotton, this, combined with a ReActivePro6 spring system, will let you sleep well and in comfort with just the right amount of support from this traditionally made mattress. The Triple Edge Protection will give you true edge-to-edge support allowing you to sleep right up to the edge without roll-off, providing an extra sleeping area for a restful night39;s sleep. Medium Tension- Good all rounder for front, side or back sleepers. *ReActivePro 6 Pocket Springs - Each spring independently senses your shape and weight distribution, providing support and total spinal and body support. The more active turns in a single continuous pocket spring the greater its ability to sense the exact comfort and support requirement of you and your partner. A single continuous pocket spring also creates a bellow-like effect that drives cool air around the mattress and facilitates greater hygiene. This extra breathability ensures better ventilation, helping to reduce moisture and maintain a comfortable body temperature for a healthy, relaxing and energising nights sleep. *Pillowtop - The pillowtop provides a sumptuously soft and comfortable cushion above the supportive mattress. *Red Tractor Assured Farms British Wool - Upholstered with 2 fleeces of pure British Wool are used in this mattress as a soft and insulating upholstery layer for added comfort. Wool is a natural insulator providing coolness in the summer and warmth in the winter. Offering superb comfort, it also has hygroscopic properties encouraging the evaporation of body moisture. This wool has the added benefit of the Red Tractor Scheme, which makes farms adhere to rigorous standards that cover the full farm supply chain, including animal welfare, traceability and environmental protection. *Cotton Layer - Generous cotton layers with responsive properties that complement the spring unit are added to the mattress to help provide a comfortable feel. The Cotton Hypnos use in this mattress is certified as sustainable. It is a soft breathable fibre, which helps to keep heat away from your body. *Triple Edge Protection - The mattress gives true edge-to-edge support as it is designed with a non roll-off reinforced edge support to ensure total comfort and provide extra sleeping area. *Solotex - Provides a luxurious cushioning fibre that promotes airflow adding to the softness and will help with shape retention. *Chemical Free Belgian Damask Cover - With a soft to the touch damask cover which provides a soft, fresh and hygienic sleeping surface. The cover uses certified sustainable cotton yarn and viscose weaved into this damask cover. *Hand -Tufted - The traditional method of mattress upholstery where the fillings are secured by hand with tufts from the top of the mattress to the bottom to ensure all loose fillings are secured to provide the perfect finish. *2 Rows of Hand Side Stitching - Traditional hand-side stitching secures the outer springs to the border at the top and bottom preventing roll-out and is the most highly skilled and labour intensive of all the operations. Side-stitching is carried out by senior upholsterers using traditional long needles and twine to make borders and edges stronger. The effects on the mattress are quite dramatic preventing the springs from distorting and extending the sleeping area right up to the edge of the bed to make the borders and edges stronger. *Flag-stitched Handles - Handles on all sides for ease of positioning. *Chrome Air Vents - Chrome finished vents to allow good air circulation, regulate temperature and keep the mattress fresh. *100 Recyclable - This mattress is 100 recyclable at the end of its life. *Easy Care - No need to turn, but regular rotation from head to toe will extend the mattress39;s life span.
