My husband and I both have Eden pillows, I have the Coop body pillow, he has the seat pad, AND we've gifted 4 Eden pillows total. So we basically love Coop everything and of course had to buy the Solstice sheets. Our initial impression was that they sleep hot. No matter which side you flip them to, it's not going to be as cool as a cotton sheet in the summer. We must have adjusted after about a week. They are super soft on both sides. The "cool" side being somewhat silky, and the warm side being more microfiber like. I will say that the fitted sheet is very deep! Even when I tuck them in super tight, it always loosens again and I have a lot of extra material bunching up under me. Our mattress is 14 inches deep I think. Our solution to this of course is buying the new mattress topper... Someone please help us! Seriously though, hoping the mattress topper is the icing on our Coop cake and will make our sheets fit more tightly so we can enjoy the soft texture more. Fingers crossed!
