The mattress topper has really improved the comfort of my bed. I sleep much better and my sciatica problems have improved significantly. But what I found a bit of the nuisance was the smell - I had to air the topper several days before being able to use it. It was also a bit of a struggle to put it in its cover by myself, as I had no one to help - the fact that the mattress topper is in two parts, is quite heavy and the material very soft and pliable made it difficult. But the effort was worth it.
