This was a gift, but I haven't had a chance to use it, so I've been storing it. I've opened the package, so I'm offering it at a reduced price. • Airweave's unique material, Airfiber®, provides excellent resilience, dispersing body pressure on areas that are strained by sitting for long periods, and supporting comfortable sitting. • Airfiber is over 90% air, so it doesn't trap moisture and is less likely to get stuffy, providing a comfortable sitting experience. • It makes sitting comfortable on various chairs, including home chairs and office chair cushions. By making the Airfiber® filaments finer than before, the feel against the skin is improved, the cover's texture is also enhanced, and the sitting comfort is even better. • The cover can be washed at home. The Airfiber filling can also be washed with water, keeping it clean. 【Color】 Gray 【Size】 Width approx. 39 cm × Length approx. 39 cm × Thickness approx. 5 cm ※ Airfiber® approx. 3.5 cm thick used 【Weight】 Approx. 0.5 kg 【Materials】 ＊Cover Surface: Polyester 55%, Cotton 45% Filling: Polyester 100% Lining: Polyester 100% ＊Cushion Material Polyethylene 100%
