Glideaway products are made of a variety of materials, including gel-infused memory foam, activated charcoal memory foam, and natural latex. Memory foam materials are supportive, yet capable of taking on the shape of a sleeper. However, memory foam can absorb and retain heat, which can be an issue for hot sleepers. Fortunately, latex doesn’t retain heat nearly as well as dense memory foam, and it retains its shape far better, making it an excellent option for those who prefer medium-firm mattresses. Both materials are naturally hypo-allergenic and completely safe.
