[Product Description Quoted Below] Designed by a chiropractor to aim for a posture that puts less strain on your lower back. When sitting on a chair, if you lean back against the backrest unconsciously, your pelvic area tends to tilt... This seat helps to lift your pelvic area, guiding you to a natural S-shaped posture from your neck to your hips with less strain on your lower back. 1. Sacrum Guard: By supporting and lifting your pelvic area from behind, it prevents your back from rounding and guides you to a posture that puts less strain on your lower back. 2. Front Guard to Prevent Sliding Forward and Leg Crossing: Sliding forward while sitting, where your lower back moves forward, is a posture that puts a lot of strain on your lower back. This guard supports you from the front to prevent this. 3. Iliac Guard to Prevent Pelvic Area from Opening Sideways The gentle rocking motion helps to align your pelvic area and makes it easier to sit for long periods. If you sit still without moving, pressure can concentrate in certain areas, making it difficult to maintain your posture. This seat has a rounded bottom, allowing you to lightly move your body left, right, or forward when you get tired of sitting. This relieves pressure and makes it easier to sit on the seat for extended periods. 022 Main Unit Dimensions ◎ Approximately Width 41cm x Depth 37cm x Height 24cm ◎ Weight: Approximately 1.8kg ◎ Seat Load Capacity: 100kg or less
