This mattress is horrible. Our granddaughter sleeps on it and it's developed a huge lump in the middle of it. We are getting a new mattress delivered today which is NOT a foam mattress. We would never have a foam type mattress again. This one is just horrible. It isn't worth letting a dog sleep on it. We wasted $1200 on it 5 years ago and it started developing the lump in the middle after the first year. DO NOT BUY THIS PIECE OF GARBAGE!!!!
