Urethane, Memory Foam About this product [Thin, Approximately 10cm Memory Foam Cushion] "Thick, general lumbar supports take up too much space on the chair seat and make it difficult to sit!" In response to customer feedback, we have developed a relatively thin memory foam cushion with a thickness of approximately 10cm. It firmly supports the lower back and back without compromising the comfort of car seats and gaming chairs. [Highly breathable mesh material] The cover uses mesh fabric. It has excellent breathability and is comfortable even for long hours of use in gaming chairs, office chairs, etc. Also, you can use it without discomfort even when used in car seats during the hot season. [Securely fixed with a belt] In response to customer feedback that it tends to slip, we have attached a belt that can be fixed to the chair. It can be securely fixed to gaming chairs, office chairs, car seats, etc. It can also be used without the belt.
