Must buy with the mattress. The mattress is just so deep and these sheets stay on them so well! They are very stretchy, breathable and comfortable. I would buy them even if I didn't have this mattress.

These are the absolute best sheets I ever owned! Soooo soft and stretchy! They stay in place and don't move at all the whole night! They are so cool and I don't sweat anymore!

The sheets have pilled and the bottom sheet is not stretchy at all. The quality of the fitted sheet feels poor and not comparable to the top sheet. Wish I had a better experience.

Love the bottom sheet but the top sheet is so stetchy that I get my foot caught in it. I think the bottom sheet is a must for the mattress but I will be using a regular cotton sheet for my top sheet.

I love these sheets. They are so soft and fit well on the purple mattress. But after the second wash they are already pilling :( I'm so upset. I followed the wash instructions. These were very expensive. Idk if I got a bad batch of sheets or what...

These sheets are so soft and breathable. I usually get so hot at night but these sheets have completely changed that. I will not go back to my old sheets!

My first set of sheets were the original purple sheets, they were lovely at first then they pilled and would move with you at night. I took a chance and got the new sheets and they're much better! We like them a lot!

Listen, I thought I knew soft sheets, but then I met these. At night you can find me happier than a clam under these supremely soft and comfy fabrics. I love them so much I bought two. Enough said.

The best sheets I have ever slept in. Literally not exaggerating one bit. I'm trying to decide on when I can afford to buy another set or two so we always have them on the bed.

We have a purple mattress on an adjustable base. We tried getting by with some other sheets, but they failed at staying in place. No such issue with the purple stretch sheets! They fit perfectly and offer a great night's sleep consistently!
