This mattress topper really improved the feel of our memory foam mattress. We had hoped our mattress would soften over time, but my back and hip issues really necessitated a softer sleep surface. This mattress topper smelled AWFUL for several days, which was unfortunate given that it's so hard to move once you unpack it. We basically had to keep removing the sheets every night for a week and leave all the windows open to air it out. It gave me headaches for a while but it did eventually settle in. As someone with back and hip issues, I'd recommend this topper, but I wish memory foam didn't off-gas so much.
