King size mattress topper (Chesham HP5)

I bought this Bamboo memory foam mattress topper less than a year ago, it’s always been used with a mattress protector. The cover also comes off to be washed. It’s in perfect condition but I understand people may not want it for its purpose. The cover unzips easily and the foam, if cut up, may make a great dog bed, or seat cushions. I really don’t want to throw it away!
