No staying power
Color: Gray, Size: King
Very soft, comfortable and easy to put on. The corners pull off every other night though. Maybe if the elastic was a bit tighter, I don't know. Would probably not purchase again.

Good sheets
Color: 18 - Teal Blue, Size: California King
These sheets are a great affordable option. They’re soft, lightweight, and comfortable to sleep on. The material feels smooth and stays fairly cool at night.
