Wamsutta® Cool & Fresh Queen Fiberbed - Queen is 60" W x 80" L . Top is 80% cotton/20% Invista® polyester. Bottom and gusset are 100% cotton. Fill is 100% polyester. Trim is 100% olefin. 400 thread count. We bought this for $129 from Bed Bath and Beyond, and it gave us a wonderful night's sleep. 9/26/12 update. We have spent 12 nights in the boat this year, and continue to love the combination of Wamsutta Topper and Sleeping bag. All we do is to rotate the Wamsutta every couple of months. We continue to insist that this arrangement is more comfortable then our bed at home.
