Cushion that supports comfortable stretching with 8 shiatsu protrusions. Product Dimensions: 53 depth x 38.5 width x 18.5 height cm Care Instructions: Hand wash only [Colors] Brown, Green [Product Size] Width 38.5cm x Depth 53cm (53cm to 97cm) x Height 18.5cm (18.5cm to 60.5cm) [Materials] Structural components: Metal (steel), Cushioning material: Polyurethane, Cover: Polyester Developed based on the know-how of chiropractic clinics, it supports the pelvis and posture just by sitting, and helps you sit comfortably for long periods. Furthermore, the pelvic hold pocket on the seat and the thick curved shape on the back create a state of full relaxation with the pelvis upright and tightened, allowing for easy "stretching." It can quickly relieve concerns in the neck, shoulders, shoulder blades, and lower back. The 8 protrusions on the back act as a substitute for massage and shiatsu, loosening the muscles around the neck, shoulders, shoulder blades, and lower back, relieving fatigue and improving blood circulation. The thigh support cushion and pelvic cushion create an incline on the seat, allowing the pelvis to stand upright and fit into the posture hold pocket. This prevents the pelvis from sliding forward and allows for comfortable sitting around the pelvis. The narrow back shape makes it easier to stretch the shoulders, and the range of motion is expanded. In addition, the thick curved shape creates an S-curve to support posture. The 14-stage gears built into the lower back and back areas allow the shape to be freely adjusted to match your body shape and areas of concern, so you can apply the protrusions to the areas that suit you, and the variations of stretching are also expanded.
