Soft but very thin
Color: 01 - White, Size: Full
Soft but very thin. Not sure these will last long. Didn’t realize how thin the were until I washed them. They do not come out of dryer wrinkle free. Not horrible but still wrinkled.

Ralph Lauren quality without the price!!
Very soft sheets!! Exceptional quality! Good fit and great value! Got them for my guest bed on queen.. but hubby slept in there a few nights due to his back hurting. Gonna get some for the master king bed this spring. These are Ralph Lauren quality! And that’s all I have on my bed until now! We are those strange people that like sheets to feel cool when you get into bed.. and these are!

Disappointed in quality
Poorly made and not good quality. I had high hopes for these sheets because I love the color. However, after only the second laundering the hem stitching on the pillowcases is actually coming undone. Sleep-quality wise, I found the sheets a little scratchy for sateen, and while we’d hoped they would “sleep cool”, that is not the case. Unfortunately I washed them so I’m unable to return. They’ll go to the end of the line for rotation in emergencies only.

Good quality
Color: 01 - White, Size: Queen
I've had trouble with other all organic bedding on Amazon but this worked out. It did shrink a bit but it's cotton so it's supposed to do that. And it still fits on my bed pretty well so no complaints.

Not quite “Hotel” quality
3.5 stars.
My initial impressions are the followng:
- Definitely not “Hotel” quality construction. I found these a bit thin and poorly stitched/constructed compared to what one would expect of hotel quality linens .
- I doubt these are 500tc. They feel very flimsy, if I had to guess based on weight and feel alone I would assume 300tc at best.
- Washing does make them softer as is typical with sateen which I would recommend before use as they feel like Polyester right out of the bag. Wash before use.
- Color was interesting, not quite as expected. The grey/blue sheets have a seafoam green tint. Not bothersome enough for me to return.
- They feel cool to the touch and should keep one comfortable while sleeping. I will update my review if that is not the case.
Overall these are good sheets, but they are definitely not great/hotel quality. I’m keeping the ones I got for my children/guest rooms but will return mine as I really do want a higher quality sheet.
