I'll start with the good stuff: these sheets ARE extremely soft and comfy! I love the feel of them. I bought them even though I saw the reviews stating they were "too thin", because we live in an old house and even with central a/c our upstairs bedroom gets hot in the summer. We also just purchased a new memory foam mattress with cooling gel from Wayfair, so I figured I'd get "cooling" sheets as well. It's only the beginning of March, so can't say for sure but they are soft and thin enough I think they will help. However, this leads me to the bad: They are super, extreme thin. I can see my pillows and mattress through them (I got the white). I am afraid they may not make it till summer. I'm worried one scratch of a fingernail may shred them. 
If they do make it, I will certainly come back and update to 5 stars because as I said they are sooooo soft! I feel like I'm in bed at a high end hotel laying on my new mattress and sheets right now! :)
