I did not like this topper. It never filled out after 4 days, It was 1 to 1 1/2 inches short on each side. It never got to 2" and the cover stayed wrinkled because it did not fill out. Did not want to take a chance on getting the same one as a replacement so the agent ordered the one I purchased a month ago for me. Did not really want a 4" on this bed but I was extremely happy with the 1st topper I ordered which was the Almeta 4" gel memory foam mattress topper. The agent was very helpful in resolving the issue even going far and above what she had to do and ordered the replacement for me. Best customer service. Don't worry about ordering on line. Wayfair will take care of you before and after the sale.
