At least, I think it's the sheets. These are soft, but you have to be careful with how you wash them because they can pill a bit, which makes them less comfortable. And sometimes they sleep a bit hot, especially in summer.

So happy we got these. They came later than the mattress so it was easy to do before and after. They make this mattress sleep almost cold. Very happy.

These sheets are amazing! We have always struggled getting sheets to stay put even after one or two nights sleep. These definitely stay put and don't even look slept in after a week. Super soft. Definitely would recommend.

I LOVE these new sheets they are soooo much better I got the morning mist - so fab!!! When I put them on the bed the have a rust stain on the flat sheet. Can I have a new king flat sheet and I will return the stained one - pretty please. Nancy

Well so far the sheets are good, the only thing I noticed is that they stain easily, so I don't know if I would buy them again plus they are way too expensive

I've never spent this much money on sheets before, but these Purple sheets are well worth the price. They fit the purple mattress perfectly and make it even more comfortable! I love them!

These sheets are the most comfortable I've ever slept in/on. They grip my memory foam mattress and never let it go. I love the purple color as well. This is my second set purchased, so I definitely came back again.

Love my purple sheets for my purple mattress.. The fitted sheet fits perfectly and never comes untucked. The softness and stretch of the material is amazing.. Thank you Purple for another terrific product!

These are the softest sheets we have ever owned. The fitted sheet stays tight and smooth with no wrinkling. We will definitely be purchasing more sheets. Highest quality ever.

These are the best sheets I have, I love them so much, especially because the corners never come undone Other than that they are super soft, breathable and comfortable I will definitely be buying more
