This fiber bed has more filling than virtually any, which is great. It is fluffy and comfortable. But, in less than 2 weeks of use, the stuffing has flattened and shifted within the large squares. Some of the seams between the squares are now completely exposed and "naked" of stuffing to the base, leaving dents that show badly through the sheets and impact comfort. Fluffing and shaking the pad has only brief and minimal effect. I don't expect it to last long before I give up. Also, it is very hot when sleeping. It should be great for winter, but it is awful now.
