I debated innerspring/gel or memoryfoam/gel and narrowed down a huge list to this one and another. I ultimately chose this one because it's more eco friendly. It's really comphy and firm. My animals and I love it. It has firm edges which is a factor for me since I frequently sit on the edge of my bed. The gel top was essential living in the south. It hasn't been very long; but, so far so good. And reading the reviews helped me decide so I wanted to make sure to leave one, too.
