This is a cushion for gaming chairs made by Bauhutte. 6 cm thick Built-in gel and urethane foam Black color You can customize your gaming chair for a more comfortable seating experience. I was using this as a base by placing another cushion on top of it, but I no longer need it, so I'm giving it away. The cushioning still seems to be in good condition. Due to aging, there are some areas where the black cover's paint is damaged, but it's on the underside, so there's no practical problem. Please understand this as a used item. Cover washed, air-dried, and treated with Febreze.
