This is a size M Relax Cushion for dogs, designed to help them relax. It allows dogs to rest in a standing position with their legs supported, promoting a relaxed state. The main body is not washable, so use it with the optional water-repellent cover. It's important that the cushion fits well, so please carefully consider the size on the manufacturer's website. Ultimately, you can adjust it with towels or other materials to suit your dog's body type and condition. The cushion is filled with bead filling. The beads will shift over time, so occasionally reshape the cushion. I received this from someone who used it previously. The previous owner used it for 4 months. Their dog was bedridden and developed severe bedsores, so they purchased this cushion. The dog seemed to relax quite a bit when using the Relax Cushion. They used towels and pet sheets to prevent soiling. The dog's condition was quite poor when they bought it, so they were only able to use it for one day. The person who gave it to me was very kind and provided a smooth transaction, offering warm words. I would like to pass this on to help other senior dogs and their owners feel at ease. ↓ I'm attaching information I received from the previous owner: The cover is water-repellent. It is not waterproof, so odors and moisture may seep through. Using it with a toilet sheet is recommended. It should be fine for the winter, but heat can build up in the areas that contact the body. They used a cooling sheet in between. Nitori's baby section and the pet section at Cainz are convenient. It's in good condition, but it has been used by a dog, so please refrain from purchasing if you are sensitive, concerned, or are a reseller or proxy buyer. No cardboard box. It will be shipped in a plastic bag due to its bulkiness. #OneAid #DogRelaxCushionM #DogCareCushion
