Chair Pad Low Resilience Cushion for Chair Black Retail Price: ¥5780 The part shown in the second photo is slightly fuzzy due to the Velcro on pants sticking to it when sitting. It does not affect use. Please refrain from purchasing if you are concerned about minor imperfections due to home storage. I have cleaned it as much as possible. Returns are not accepted unless there is a significant defect. Thank you for your consideration. Material: Memory Foam Pillow Type: Floor Pillow Color: Black Size: 38cm x 45cm Brand: IKSTAR Shape: Butterfly [Recommended for those who sit for long periods] Sitting for long periods can put a strain on your lower back. This chair cushion uses high-quality low-resilience material, which excellently distributes pressure on the buttocks, providing excellent comfort. It has a three-dimensional structure that envelops and supports the buttocks, making it a low-resilience cushion that allows you to sit comfortably for long periods. [Three-dimensional design that envelops and supports the buttocks] The slight indentation and sides naturally fit the buttocks, distributing pressure. [W-shaped design at the front] Both sides absorb pressure well. It naturally conforms to the buttocks and gently envelops them, providing an excellent fit. [U-shaped design at the rear] The unique U-shaped structure avoids the coccyx and other vulnerable areas, improving the shortcomings of conventional cushions that compress the coccyx. It reduces pressure on the coccyx from a seated position, gently cares for the coccyx, and provides comfortable seating. In addition, this unique design improves the breathability of the cushion, making it less likely to get stuffy even when sitting for long periods. [Low-resilience material & high-quality product] Made of low-resilience polyurethane, it firmly supports the body, distributes pressure on the buttocks, and will not deform even after sitting for long periods. [Highly breathable mesh fabric & non-slip backing] The cover is made of mesh fabric, which is highly breathable and prevents stuffiness. The cover has a zipper, so you can remove and wash it, making it easy to care for. The back is non-slip, so you don't have to worry about the cushion falling off the chair.
