Material: Airfiber is our proprietary material made of interwoven high-density polyethylene fibers. It's essentially strong and breathable while memory foam is a type of viscoelastic polyurethane foam that conforms to your body shape when pressure is applied. Feel: Airfiber offers a firm feel with high breathability due to the spaces between the fibers while memory foam offers a pressure-relieving, contouring feel that can sometimes feel hot due to its ability to trap heat. Support: Airfiber is designed for proper spinal alignment and pressure relief, particularly for back, stomach, and combination sleepers. Memory foam can offer good pressure relief but may not provide optimal support for everyone, especially side sleepers. Temperature Regulation: Airfiber is generally considered cooler due to its breathability. Memory foam can trap heat, making it less ideal for hot sleepers. Movement:  Airfiber allows for easier movement and undisturbed sleep due to its high rebound nature. Memory foam can have a sink-in feeling that might make it harder to move around. Washability:  Airweave mattresses completely washable, while memory foam mattresses are not.
