I have had this mattress topper for about 3 weeks now and it's such a big difference. There was really nothing wrong with my mattress prior to buying it, well that's what I thought before I bought this. Its super soft but still very supportive which is exactly what I needed. Really one of the best investments I ever made. I agree with all the other reviews about the smell, but it went away in about two days. So it wasn't a huge deal. Over all this topper was great and especially for the price.
