Purchased king size taupe.  Color is good.  Fitted sheet fits very snugly on my 10-1/2" Tempur-pedic with mattress pad.  I have concerns that it would fit as well on a 15" mattress.  Flat sheet is amply sized for secure tuck at bottom with sufficient overhand on sides.  Fabric is very thick but still feels cool in my southern summer heat.  I like the smooth feel of the finish.  Because the fabric is 100% cotton, they do wrinkle but I don't consider that a problem.  I wouldn't hesitate to purchase another set.
