I bought these specific sheets
"I bought these specific sheets because I have a Casper mattress and wanted sheets that would actually fit. They do not fit. There's a least a foot of "extra" material - in the fitted sheet! - that hangs off both sides of the mattress. They are pretty much unusable, which is disappointing because they weren't exactly cheapy sheets off Amazon. But Cheap off Amazon is exactly what I will have to do, because these bunch and create huge lumps in the middle of the mattress because they are way too big and deep."
