Convoluted foam, also known as egg crate foam or eggshell foam, is a polyurethane padding with a distinctive wave-like profile. It is widely used for mattress toppers (pressure relief), acoustic panels (echo reduction), equipment cases (impact protection), and filter media.

Egg crate foam is a kind of flexible open-cell polyurethane foam with a unique wavy and egg-carton-shaped surface. It is lightweight, soft, and highly resilient, making it one of the most widely used cushioning and insulating foam materials on the market.

The special peak-and-valley design of egg crate foam brings many practical advantages. First of all, the uneven surface creates gaps for air circulation, which greatly improves air permeability and heat dissipation. It avoids stuffiness and sweating, so it is commonly used for mattress toppers, seat cushions and bedding padding to provide a cooler and more comfortable touching experience.

Moreover, egg crate foam features great sound absorption. Its porous and undulating structure can effectively absorb and weaken sound waves, reduce indoor echo and noise resonance. It is a cost-effective acoustic material for recording studios, offices, home theaters and equipment rooms.

Easy to cut, shape and install, egg crate foam is available in various thicknesses and densities. It is durable, odorless and eco-friendly, suitable for daily household use, industrial packaging and sound insulation decoration.
