Bright green balance board with mesh fabric, curved design for improved stability. Length: Approximately 63cm Width: Approximately 30cm Height: Approximately 38cm Weight: Approximately 4.3kg I thought it might be good for stretching my back like a massage chair, but I haven't had many opportunities to use it. Used a few times. However, there are some stains that occurred during storage. There are one or two spots on the back, as shown in photo 4 and photo 5. If you understand this, I would be happy if someone could use it m(*_ _)
