I was hesitant to purchase another topper because I feared the odor would be something I couldn't live with. To my great relief it was just fine after I aired it out for about a week. I gave it only four stars because the dimensions and package weight didn't add up to a density of 5.3 pounds per square foot. When I converted the dimensions in inches to feet (59x76x3 inches), multiplied the three dimensions in feet to get cubic feet and then divided by the package weight (26 pounds), the highest density it could have was 3.3 pounds per cubic foot. In spite of that, this topper gives great support. I have a problem with bulging disks and arthritis in my hips. After sleeping on this topper, I have zero pain. I found it best to turn the topper over once a week to eliminate any lasting impressions from forming. I definitely would purchase this topper again.
