This is the 2nd Slumber Solutions Gel 5.5-inch Twin/ Full-size Memory Foam and Fiber Mattress Topper that I purchased from Overstock.com. I never write reviews on companies as a rule. However, it just must be said that for such a high end high quality item I just can't believe these low prices and great service. The same item right now on Price Grabber.com is $209. and shipping is not free. This is a great item and representative of my overall excellent experience with Overstock.com. I could not be more pleased.
