There was a choice of two Slumber Solutions Gel toppers. I chose the one that was more expensive and seemed denser. I think I got the one with the deeper pillow top indentations that looked less dense and was cheaper. The topper was advertised to be 3.2 lbs density, but it is much too soft and there is too much give in the topper for this to be accurate. At least half the depth of the 3 inch topper is the pillow top part with only 1 1/2 inches of any substance. I have had memory foam toppers before, so I have experience with them and this product is not up to the quality of the other toppers. Also, just by airing out the topper, before it was even used, I found small tears that were not there when first opened. I did not move the topper roughly, or any more than any normal use of placing it on a bed. I would have considered returning it but company was coming to visit and I really needed it for a very firm mattress on the folding sofa bed in the guest room. I'm not sure how to store it when I fold the bed back up; I'm concerned it will rip some more and leaving it on the bed is an option. I don't typically write reviews, however when I bought this product there were no reviews available to help me decide, and I think others should be warned.
