My experience of this memory foam is that it was great for the first few weeks. Felt my firm new bed needed some cushion, my husband loved it, but after 1 month I had so many issues with the right side of my back, shoulders and neck...the muscles would just go into a spasm. It wasn't until I was on a trip that my back calmed down after sleeping on a hotel bed. I immediately took the topper off when we got home and took some IB Profin that my back became stable....so in this case...I would say, the topper was great, but not for me. My kids are in college and we got them twin topper sizes 4 inch...and they LOVE their beds with toppers.
