I just have to say-after only 3 weeks sleeping on this topper-my back problems have been reduced, my sleep is SOOOOO much better(haven't slept all night long in almost 20 years). I opened the package and the new foam smell for me was basically not there-very faint and rather pleasant. Cover with the topper pad, clean sheets and you are "good to go"! The gel foam does what is advertised-no heat retention-and I did have hot flashes to handle at night too. If you are looking for the best deal in mattress toppers-this is so worth the money!
