1. Ergonomically Adjustable Thanks to the ergonomic design, the backrest can be adjusted into 6 positions (0 to 80 degrees), from a low reclining angle to an upright sitting position, allowing users to find their resting position for maximum comfort. 2. Comfortable The backrest is made of thick steel tubing and breathable fabric. It supports a body weight of up to 150 kg and provides stable support for the neck, head, and lumbar spine. An additional cushion at the bottom stays in place without slipping, and a head pillow enhances comfort. 3. Removable and Easy to Clean The headrest and breathable fabric are detachable and washable. The surface of the steel tubing is treated with baked paint, making it easy to clean and maintain. 4. Portable and Foldable This backrest weighs only about 3 kg and is easy to carry. When folded, it is slim and can be conveniently stored under a kotatsu or low desk.
