The smell was great for the lavender but it was a little strong for my husband.  There is a lot of cushion provided from the 4 inch foam however, if this is on top of a normal mattress that isn't extremely firm then you may be more uncomfortable.  You almost sink too much into it when there isn't a firmer surface below it.  My husband has back issues and this seems to have aggravated his lower back pain more with it on.  We had bought it to see if it could help him sleep more comfortably thinking the memory foam would help provide more stability but it didn't help since our mattress wasn't really firm to begin with he just sunk in more.
