I have never used anything but 100% cotton sheets before, so I wasn't sure how I would like these, but I was pleasantly surprised at how comfortable they are.  These are super soft and I like that they feel less stiff than 100% cotton sheets do.  They have a silky feel to them without the slippery nature of actual silk.  It's the perfect blend of cotton and polyester  that make this sheet set both extremely comfortable and soft without being too slippery, silky, stiff, or hot.  The corner pockets on these are the deepest I've seen, and when I put the fitted sheet on, I have to tuck a lot of the sides under our mattress because the pockets are made so deeply (we have an 11" mattress).  My husband and I are warm sleepers, but these sheets help keep us cool all night.  I find that they are so comfortable I don't want to get out of bed in the morning!  These are quality sheets that perform well and keep you comfy all night.
