Have had the mattress topper for a month or so. Put on a too firm 2 year old mattress. Provides just the right amount of softness; isn't hot like most memory foam; stays in place on the bed without the straps and looks as good as it did when i unpacked it. No smell, great company and speedy delivery. Plus of course all the eco benefits. I suffer chronic low back pain (osteopenia) which has disappeared at the time of reviewing and put that down to a combination of the topper and exercise. A very comfortable night's sleep these days.....highly recommend this purchase after a great deal of deliberation.
