These clips hold the sheets on so well! They keep the corners from popping up while sleeping, if they stay latched. Yes my sheets are now wrinkle free. Overall these clips work great!

Love this product. Worked great. Excellent design. Well worth the money. Totally worth it though. Very pleased.

They are cheaply made and a terrible design. Do not recommend. Don't waste your money.

The sheet holder straps are roughly 12” across and need to be centered under the mattress. I have no clue how someone with a bigger bed could attach them without having help.
