Great summer sheets
Color: Light Blue, Size: Queen, Color: Light Blue, Size: Queen
Love these sheets! I washed them before using. Went by the manufacturer's instructions and they came out beautifully. I purchased these for my summer sheets, and they are very soft and comfortable and really keeps me cool at night. I purchased the light blue, but they are more like aqua green. Not saying I don't like them, the color is very pretty. But if you are looking for light blue, they are not quite that. Are there wrinkles? Yes, of course. They're 100% cotton. Did it interfere with my sleep? Nope. Not at all.

100% cotton
Color: Dark Gray, Size: King
I have a king size hybrid Purple mattress, and while the fitted sheet pockets don’t exactly fit all the way to the bottom, they didn’t really have issues with riding up much. I just pull them back down when making the bed, and it’s not really an issue. They are a little crunchy at first, but I think they soften with washes. I appreciate that they are 100 percent cotton which was my reason for purchasing. For the price, I am satisfied, and will probably purchase more if I can’t find anything comparable with deeper pockets. I would consider them to be a good mid weight, breathable sheet set, making them nice year round sheets. I haven’t had any pilling issues yet, I will continue to use to be sure this doesn’t become a problem before I purchase another set. The gray color is very pretty and neutral, making it match with many other color schemes. As of now, if the pockets were just a little deeper, I’d give 5 stars.

Great Buy
Color: Sage Green, Size: California King
Pros: correct color as shown, lightweight, breathable at night, great for sensitive skin, fits corners of bed
Cons: after 2-3 washes, even following wash instructions the sheet does get smaller making it harder to fit bed.
Overall 10/10, would recommend buying & I will buy in future.

Scratchy, not soft, smell really bad at first, don't look great.
Color: Good Vibes, Size: King
Out of the bag these smelled really toxic. I pulled some loose threads, of which there were many, and did a burn test. The stitching threads are synthetic. Then I pulled a fabric thread, this burned natural. After washing, the smell was gone. These fit the bed ok. They are, I dare say scratchy. I hope they soften with washes. They look old immediately after wash.

Perfect for my little hideaway
Color: Wesley Taupe, Size: Twin, Color: Wesley Taupe, Size: Twin
We converted an old small treehouse into a cozy nook for adults and kids alike. I ordered this sheet set for the twin mattress because the color and vibe match the decor.
They're lovely and did exactly what I wanted for the space. They're soft and a perfect thickness for the warmer months. It gets hot up there in summer.
The mattress is 5" memory foam, so these have a little extra "give" for my mattress and should fit a standard mattress just fine. Very cozy.
They're only printed on one side, which is common for most patterned sheets. They're soft out of the bag and breathable.
The fitted sheet has elastic all the way around, so they seem to stay on so far. Nice sheets!
