One of the leading benefits of memory foam is its ability to prevent pressure points. Open-celled memory foam does not resist body weight, rather it compresses, conforming to the sleeper and distributing weight across the surface of the bed. A memory foam mattress allows the sleeper’s body to assume a natural, neutral curvature and maintains lumbar support. The dense cellular structure of memory foam is naturally inhospitable to microbes and prevents the build-up of allergens like dust, dust mites and mould.
