Please refer to the second photo for the size chart (M PLUS). Memory Foam: The EHEYCIGA dog bed is designed with a combination of memory foam and egg crate foam to evenly support the body and distribute pressure. It offers a great balance of flexibility and support, making it particularly effective in reducing stress on the joints of senior dogs. Sofa Design: This dog bed features a three-sided long pillow structure to firmly support the neck and head, promoting stable sleep. The pillow sections on both sides are designed to allow dogs to snuggle up and sleep more comfortably. Waterproof Fabric: A waterproof sheet is sandwiched between the polyester fabric, keeping the dog bed clean and dry. However, the linen sides are not waterproof. Comfort and Various Sizes: The surface of the product is covered with soft fabric, providing a comfortable sleeping environment for pets. Available in sizes to accommodate small to large dogs. Recommended for cats as well as dogs. Care Instructions: Our dog bed comes with a removable and washable cover. The cover can be machine washed after removing the inner material. However, please note that the foam itself cannot be washed. It will expand to its original shape within 24-48 hours after opening. #PetCushion #PetBed
