Premium Captain's Chair Felt Cushion - Non-Slip, Comfortable Seat Pad for Office, Gaming & Dining Chairs - Home & Office Ergonomic Support (Black)

The clever shape of the matching felt cushion ensures that it automatically and immediately ‘clicks' into place without requiring any fastening system. This keeps it from being blown away by the wind. The manufacturing technology was copied from the automotive industry. When not in use, store cushions indoors.
