Color: Navy MEIDAI select Supports correct posture just by sitting, enveloping the pelvis☆ The three-layer structure of low-resilience, high-resilience, and rigid urethane tightens the pelvic area when in use. A hole is provided in the area where the ischial bones are most compressed, considering the shape of the ischial bones, to reduce the burden on the ischial bones. The upper layer of high-resilience urethane wraps the pelvis from the sides and back, providing firm support. The combination of low-resilience and rigid urethane prevents sinking, reduces the burden on the ischial bones and lower back, and makes it less tiring to sit for long periods. A 7-degree slope maintains a natural, beautiful posture, and when in use, it also slims the protruding lower abdomen! The three-dimensional three-layer structure wraps the outer thighs from the hip joints. ■Detail The fluffy-touch pile cover is removable and washable. Non-slip processing on the back. ■Size 31cm long x 42cm wide x 8.5cm high
