One of the worst sets of sheets I have bought. They wrinkle so bad-straight out of the dryer. Look like they have been crammed in a suitcase for weeks! Also, not very soft~even after a few washing’s, stiff and rough to the touch.
Be careful of the king fitted sheet. 76" x 80" will be a tight fit.
Industry standard is 78" x 80" and even that is pretty snug on a deep mattress.
