EDIT - seller issued refund so all's well.Came with a split in the seam several inches long. Poor craftsmanship.I really liked these sheets I order three of them for each room I have thank youOne day our aging cat peed on our mattress so we bought this cover to stop more accidents from getting on the mattress. Well, right after after everything was all clean and put together with the mattress cover I laid down for bed and my whole back ended up soaked from another accident. I hope it was an accident anyway and not her retaliating because I started shutting my bedroom door. My door doesn’t shut all the way unless you pull hard on it so she was able to push it open with her head. Anyway, when I lifted up the mattress cover I was quite pleased to discover that it did exactly as it claimed. My mattress was safe, I don’t even know it’s there unlike the crappy plastic my mother put on our mattresses as kids.These waterproof mattress covers are really nice. They’re thin, soft, don’t pop off of the mattress and don’t make any crinkle noises.Very soft, comfortable and easy to clean. Highly recommend.Attractive appearance, fit my new mattress like a glove. I poured a 6oz glass of water on it to test if it was truly water resistant..it is!Highly reccommend.Perfect!! Does not make any sound when goi g to sleep. It is great!Love the sheets ! Yes, wrinkle free
