The best-looking, softest, and thickest jersey sheets I have ever bought. My mattress is 14 inches thick, and although the corners do fit, the sides arch up to display my mattress and it simply looks shoddy. Despite the fact that it claims the fitted sheet can fit a mattress up to 17 inches thick, it won't. Both the sides and the ends experience this. I do not have many "visitors" to my bedroom, but if I did, they would all be able to tell what kind of mattress I use because the branding is so obvious.
