Flexible polyurethane foam is a versatile material used in many products. Polyurethane foam can be found in upholstered furniture and mattresses. It is also widely used to create costume accessories. The flexibility of the material makes it easy to bend a shape instead of having to carve all of it, but this soft material is fast and easy to carve with patience and some simple tools.
