Color: Black Size: (approx.) 38cm (H) x 45cm (W) x 4-11cm (D) Material: Core: Polyurethane (high-quality memory foam) Cover: Surface: 100% Polyester (breathable mesh material) Back: PVC material (with anti-slip and anti-stick particles) Year of Purchase: Purchased on Amazon in 2025 Accessories: 2 original bags and instruction manual (??) Washable, Anti-slip, Breathable I tried using it, but it caused back pain, so I don't think it suits my office chair. The Amazon reviews are very highly rated, so it seems to be popular with many users. I've only used it for two days, so there are no damages or scratches. (This is just my amateur assessment) I will ship it folded in half, similar to Amazon's shipping method. I will use the original box. Please note that the cushion has been stored for a long time. Please read my profile before purchasing. Thank you in advance.
