This was my eighth memory foam topper to purchase, and it is by far the best of them all. Sleeping on a memory foam topper is like laying on a giant puffy marshmallow without the stickiness, or like laying on a pile of newly fallen snow without the wetness or cold. Don't waste your money on more than a four inch topper though, as most of it is nothing more than regular foam you are paying for. The four inch memory foam topper is perfect. Just don't be surprised if you fall asleep the first time you lay down on it. Yes, it is that comfortable. One word of advice is to buy a size larger than you need, then trim it with an electric carving knife. You can always use those extra pieces to pad a chair you enjoy sitting in. Just cover it with a throw. The toppers never seem to fit a bed perfectly unless this is done. Electric carving knives are perfect for this. Oh, the odor from this topper was not bad at all compared to some of the memory toppers I have purchased at other stores locally. It was not hard to get out of the box either as some of them were previously. Thank you, Overstock for sending this promptly upon my ordering. I am very well pleased with your product. Compared to the other seven toppers I have purchased for my family, this one is the best of them all.
