I have no idea what the technology behind these sheets are but they clearly are without a doubt the most comfortable sheets I've ever experienced. I have recommended them to 3 people already. Thanks, Life just got better. Patrick

I can say that I have not slept better in years. I am truly beyond satisfied with Purple Sheets. I have never felt anything like them. Can't wait for the cold weather!!

Sent a cal king when I ordered a king. Everything still fit except the top sheet which was not even close to being able to fit. Everything else is nice though.

I really like these sheets. They stay in place when you move around on them. I'd definitely recommend these sheets to anyone questioning whether or not to buy them.

I wasn't sure what I would think of stretchy sheets but they are awesome! They are so soft and wash up well! One of my packages got lost in the mail and it was replaced really fast. I will order again.

We recently purchased the purple hybrid 3 and mattress cover and now the sheets, we are definitely on the Purple train!! PS, these are the second set of sheets, which are arriving tomorrow...excited to have our second set!

I am a wild sleeper and i always had issues with my old sheets every morning being of the bed but since I bought the Purple sheets my sheets are still on in the morning!!! I love them...

I bought the bigger size at first I thought it was too big, but switched to the regular size and I am very happy. Definitely comfortable. A little bit on the pricey side but well worth it for me.

I researched for best comforters out there and purple had high ratings. I said why not? Since then, I bought several of their sheets and chair supports. I just hope they come up w more color options.

I already had a set of these sheets and a mattress from Purple. The sheets actually help me sleep since they don't bind my feet and I can move freely during sleep. The sheet also seem to keep me cooler at night, I'm a hot sleeper.
