Purchased in 2024. Used for my elderly dog. I placed it on areas prone to bedsores, and was able to see him through to the end without any bedsores. I have removed and washed the cover. Thank you. Large size, for all dog and cat breeds Outer diameter: approx. 20cm Thickness: approx. 5.5cm Soft-touch fabric Washable (cover only) Waterproof cover Thickness adjustable I have disposed of the original packaging bag, so I will ship it in another bag.
