I was so tired of spending big $ on expensive Sleep Number brand sheets that were poor quality and ripped so easily! I thought I’d take a chance on these and I’m so glad I did! The quality and fit are great! The only reason I’m going with 4 stars instead of 5 is because I really expected 600TC to feel softer than it does. Not sandpaper by any means, but a little softer would make them 5 star sheets for me. I’m about to buy a second set and will never pay the Sleep Number company for lousy quality sheets again!
