This is my second purchase of a Memory Foam Mattress from overstock.com, and I am just as please as from my first purchase. I confirm with most reviews, that the odor is strong but does go away in time. Putting the mattress together was simple enough by myself, and even though the layers didn't line up exactly it looked just fine after placing the included cover over everything. Was concerned about it being for an RV, but fit atop my futon frame just fine. As for comfort...... there is nothing like memory foam for myself. I have lower back issues, which are basically gone as a result of these mattresses. Liked the fact that I was able to google information on Accu-Gold and was very impressed with the website I located, and all the information it provided about the material being used. I layered everything soft to firm from top to bottom, and really enjoying my sleep now. Highly recommended for the price!
