I bought a mattress from Way fair that was not the most comfortable. I would wake up in pain daily. I researched mattress toppers and chose this one. No more pain! It's a little expensive but it's thick and my body sinks into it while the mattress below keeps things firm. I love it! The cover is great quality as well! There was no smell and I didn't have to wait too long for it to puff up to its full size.
