Foam and cushion inserts are widely used in furniture restoration, cushion making, and various interior and craft projects. Upholstery foam provides the necessary softness and support for seats and backrests, while cushion inserts give decorative pillows their shape, volume, and comfort. The properties of the filling material directly affect the comfort, durability, and overall appearance of the finished product. Therefore, foam and cushion inserts are essential materials for both restoring upholstered furniture and creating new interior elements.
