Dinos Professional Shiatsu Therapist's Seriously Thought-Out Lumbar-Relief Pelvic Seat Color: Red List Price: ¥11,900 [Below is a product description quote] Designed by a shiatsu therapist with the aim of achieving a posture that puts less strain on the lower back. When sitting on a chair, if you unconsciously lean back against the backrest, the pelvic area tends to tilt... This seat helps the pelvic area stand up easily, guiding you to a natural S-curve posture from your neck to your hips with less strain on your lower back. 1. Sacrum Guard: By supporting and raising the pelvic area from behind, it prevents the spine from rounding and guides you to a posture that puts less strain on your lower back. 2. Front Guard to Prevent Forward Slipping and Leg Crossing: Forward slipping, where your lower back moves forward while sitting, 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 the Pelvic Area from Spreading Sideways The gentle rocking motion helps to align the 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 gently move your body left, right, or forward and backward 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 ◎ Approx.
