I bought this to soften the new mattress my husband and I bought. He loves it, but once I slept on it I realized the mattress was really too hard. (Simmons Beautyrest World Class, "Plush Firm" comfort level with the heavier coil gauge of 13 1/4" for those of you who are wondering the specifics of the mattress)This topper was the perfect level of softness--I definitely felt cushioned, with a sort of pleasant sinking sensation. Prior to the topper I was always getting a numb feeling on my hip and shoulder when laying on the new mattress--but now that feeling is completely gone.It definitely has a smell when it arrives--I aired it out for a day outside which has pretty much eliminated it, not to mention that I put it under our waterproof mattress pad so any remaining smell wouldn't permeate--so be prepared to wait a day or two before you can use it.The price on Overstock was definitely better than anywhere else I searched.
