Duroflex is AQA (American Quality Assessors) certified and member of the International Sleep Products Association (ISPA) therefore updated on latest research and developments. Duroflex Pincore Latex Foam is made from 100% natural rubber Latex by the patented Dunlop method. It is a breathable and highly resilient material that conforms to your unique body shape and weight. Latex gives you the feeling of sleeping ‘on’ your mattress, not ‘in’ it. It is popular amongst people who want firmer support and love natural chemical free products. Combining different densities of PU Foam, based on body weight distribution supports the body at different pressure points providing greater spine support and offers the right sleeping posture. At Duroflex, we have combined multiple densities in five zones, to make our PU Foam mattress sensitive to the weight of the human body and provide relief to the different pressure points.
