LOVE this topper! I read a LOT of reviews on all the different memory foam mattress toppers before I decided on this one. It is the perfect amount of softness for my taste. I love that it came with the cover as well. It gives it just a little bit more softness and prevents the topper from moving/sliding. I owned a 2 inch topper before and thought it was great...but the 3.5 is even better! There are severaI comments concerning the smell when it arrives. I did smell a slight chemical smell...but it was not extreme. I aired it out for only a couple hours and it was fine. I highly recommend this item for purchase.
