Cushion to support the pelvis and improve posture 【Beauty Starts with Posture】 "Keeps for beauty smart," born from nishikawa's sleep science, naturally maintains ideal posture. 【Triangle Support System(R) (Patent Pending)】 Supports three areas: "sacrum," "ischial bones," and "thighs." By gently holding the sacrum and ischial bones, it naturally maintains an ideal sitting posture with an upright pelvis, keeping you comfortable and less tired even after long hours. 【Distributes Pressure Concentrated on the Ischial Bones】 When sitting without a cushion, pressure concentrates on the ischial bones. When using the Keeps cushion for beauty smart, the pressure on the ischial bones is reduced. The structure distributes the pressure on the seat surface to the back, allowing for comfortable and prolonged sitting. 【Various Features to Maintain Comfortable Sitting】 ・Consideration for breathability... Air holes (ventilation holes) are placed on the thighs, which have a lot of contact. It's less likely to get stuffy even after sitting for a long time. ・Non-slip... Non-slip fabric is used on the underside of the seat. Reduces the stress of slipping from the chair. ・Antibacterial treatment... Antibacterial treatment is applied to the side fabric (outer fabric) for hygiene. ・Washable... The side fabric can be removed and washed in the washing machine. (Please use a laundry net) ・Durability... Uses high-resilience, high-durability urethane. Less bottoming-out feeling, and a rich sitting comfort lasts for a long time. My mother purchased this, but she didn't have a chance to use it, so I'm putting it up for sale. It is an unused item, but it has been opened once and stored at home, so I will sell it to someone who understands. - Brand: nishikawa - Product Name: Keeps for beauty smart - Color: Gray - Design: Pelvic/Posture Correction Cushion - Retail Price: 14,300 yen Thank you for viewing.
