I agree. We've had sheets that supposedly fit a queen size, but are infuriatingly "just shy" of fitting without bending up the freaking corners of the mattress and forcing them over -- only for another corner to pop off. I recently threw a set in the trash out of rage... maybe they shrunk slightly in washing, I dunno but there should be some extra size to compensate for this. I don't need to bounce a damn coin off of my bed.

gotta check your mattress depth. they make standard, deep and extra deep pockets. it's important

basically now tall is your mattress? queen means nothing to the depth. I've had a pillow top and it was about 8-9 inches tall. my current is a 100% memory foam and it's only 5 inch deep. the memory form fitted sheet, will never fit on the pillow top. the reverse, the sheet slides around.

That makes total sense! Duh. Had not considered that.

Your mattress is too thick you need a thinner one

Neat, thanks. I have thought someone must have invented something like this; I might try them.
