We wanted to add a little more softness to my daughter’s hybrid mattress. This topper is very comfortable and soft. We haven't had any problems with it at all, the mattress topper was well packaged, we did not experience any chemical/bad smell from it, we waited 36 hours to let the foam to expand. I am very pleased with this product and I recommend this topper if you want to add an extra comfort to your current mattress.
