When ordering this item I was unsure about which topper to choose, but now know I made the best choice. When it arrived it was cumbersome to get onto the bed by myself, but I was able to handle it. Once unwrapped, I did detect a slight odor, but it dissipated after a few hours. I wA not getting a restful sleep on my mattress, but this topper has changed that. The level of comfort it has given is outstanding. The only problem I have encountered is wanting to lie in bed in the morning rather than get up!
