I was excited about this sheet purchase. I have a Sleep Number queen size bed and needed a quality fitted sheet with some good elastic to keep it in place. I didn't go with the Sleep# this round because prices are outrageous and I just couldn't afford it. 
These claim to be deep pocketed, and they are. They claim to stay put, and they pretty much do they leave a bit of wrinkling but not bad. They do not claim not to peel, but unfortunately they do and they do terribly bad. The photo included is after one night on freshly washed sheets.
My husband moves a good deal in his sleep and these sheets leave small roles of fabric behind though big enough for him to feel them. I don't know how long they will last but at this rate I will have a large hole the size of my husband in the sheet. 
I would not purchase again because for the price I don't believe they are worth it. I will purchase quality sheets and add more elastic to the corners instead. Not quality sheets.
