As shown in the photos, this item was just purchased this month. It is in brand new, unopened condition. I bought it to try out for using a desktop PC while lying down, but I found that the desk was too low and would hit me due to my body and the thickness of the mat, so I will be selling it. I purchased a mat that is not cheap, but is more robust than a typical mat. The following is a copy from the product page. Brand: kyako Color: Gray Size: L65*W55*H19(CM) Material: 100% Urethane Use: Both legs, Back Product Hardness: Slightly firm 【Product Details】Size when in use: (approx.) 55 x 65 x height 19cm | Packing size (approx.) W18 x D18 x H37cm | Weight: (approx.) 1,100g | Cover material: 100% polyester | Filling: 25D high-resilience urethane 【Larger size than commercially available products】 Based on customer feedback, the size has been increased from the typical 50cm x 60cm to 55cm x 65cm. While maintaining ease of carrying and storage, it can now accommodate a wider range of body types and heights. 【Slightly firm 25D high-resilience】 At first, a soft pillow may feel comfortable, but when used throughout the night, a slightly firmer one is better for the body's fit. This is a masterpiece crafted by a 26-year-old veteran of urethane, with solid support and durability, and you will feel the quality improve the more you use it. 【Just right 16°】 If the angle is too low, it will not be effective, and if the angle is too large, it will affect sleep. After repeated research and experiments, we finally decided on this gentle 16-degree angle. While achieving an effective angle, it minimizes pressure on the coccyx and pelvis due to the tilt, achieving the right balance between effectiveness and usability. 【Velvet cover you'll want to touch forever】 You'll be fascinated by the smooth texture and want to touch the velvet cover. The U-shaped zipper makes it easy to remove the cover, and you can keep it clean even after long-term use.
