I bought two sets of these for a newly purchased queen sized bed. Unfortunately, the new bed has a deep mattress and while the fitted bottom sheet fits the mattress, the top sheet is too narrow and can't be tucked in well. The included pillow cases are standard size which don't match my pillows. The fabric from which they're made is slightly "sticky," causing pajamas to bunch up uncomfortably. It's sort of like sleeping on jersey or velvet. Not the best, but they were relatively inexpensive.
I never purchase microfiber but thsee had good reviews so thought I'd give them a try for some vacation rentals I have. I tried sleeping in them one night and hated them! They grab you and are hot, not breathable like cotton. The top sheet is all over the place in the morning. I bought 4 sets and sent all but the used ones back. Overstock wfave me a prompt refund. It doesn't seem to matter how much you pay or what the reviews say, if you hate micrifiber, these are a big NO.
