Soft comfortable fabric
Size: Full, Color: 06 - Sand
Super soft and comfortable! Washes well, nice color, good quality. Fits my mattress perfectly but not sure it would accommodate a mattress topper. Overall very satisfied with this product.

Must purchase
Size: Queen, Color: 01 - White
My favorite sheets. Super soft and also thick. I have had them throughout my time in college and each time I have purchased a new size mattress I have bought these sheets. Super easy to wash and get stains out of. I have white and they are still white after a year and a half.

Very comfy
Sheet feels super soft, but tough. Hopefully they're sturdy/thick enough to handle my husband's sandpaper feet and last longer than those cheap thin jersey sheets from Walmart. So far, though, totally impressed.

Sheets are not sized to fit.
Size: Twin XL, Color: 07 - Taupe
These XL twin sheets do NOT fit my xl twin mattresses. They are too long length wise and too short width wise. I have tried to use them several times and each time they do NOT stay on the mattress for even one day. I am very unhappy with the sizing and if I could return them I would. Was just a waste of good money in my opinion

Not Happy - Faded
Size: Twin XL, Color: 08 - Dark Blue, Size: Twin XL, Color: 08 - Dark Blue
I really wanted to love this but ended up super disappointed in this cover sheet. It was a generous size & nice fabric
BUT it faded in the center of the sheet where my child slept on it. Here are pictures to show the side of the sheet against the faded area. I would not recommend it although I like that it's organic.
