honestly, I was a bit hesitant to order, as I have had bad experiences with cotton sheets in the past not living up to the hype. That is NOT the case here. This set of sheets washed up well with no pilling or shrinkage.. they fit my deep mattress (16") and most likely would fit a deeper mattress than mine without an issue. these are so soft and comfortable to lay and sleep on. I absolutely would recommend this product. Give it a try you won't regret it!
