This was a purchase made for our furry family member, the dog. Her cushion in the bed had become very worn, however, the actually bedding was in great shape. After comparing numerous dog beds, and the materials they were made of (memory foam), I decided it would be a great idea to purchase a memory foam topper and cut it to fit her bedding. It works great, and there was enough material for 3 beds! (She is a medium sized dog). The two important factors when purchasing memory foam are thickness and density. The toppers density is wonderful, and she really seems to like the support it gives her. It is dense enough that when I place my hand on it, the impression stays at least 60 seconds. I found the thickness to be a bit deceiving, because some of the zones (the ridges) in the topper were definitely 3 inches while other areas were not. Overall, this was a great purchase. It is actually better material than the top on our pillowtop mattress. I would buy again for human or furry family members!!
