Your circulatory system is key to maximising the rejuvenating benefits of Sleep. The main functions of the microcirculation are the delivery of oxygen and nutrients and the removal of CO2, metabolic debris, and toxins. The “cradling” effect of the Gel-Tek Comfort Foam layer supports your bodyweight over a bigger surface thereby reducing pressure on internal veins and arteries etc. Adjusting the base to the Zero G position takes tension off lower back muscles thus allowing better blood flow whilst at the same time elevating the lower limbs. This assists the return blood flow and lymphatic drainage from the extremities thus avoiding the accumulation of toxic products and CO². The unique Circulation Booster system in the mattress offers 20 different treatments designed to enhance the circulatory systems in your body.
