It is like a large headband around a mattress. You tuck your sheets in and they stay tight. It is handy to stick a remote in so it is handy and helps huge with keeping the sheets on.

Love love love this product and would recommend it to absolutely anybody who hates tangled up sheets. Keeping my fingers crossed.

The fasteners seem cheap and shoddy. Half of them broke as soon as i tried to install them on a sheet. Not much faith in their own product.

Never could figure out an easy way to fasten these on my fitted sheets. Even with the straps fully extended, this just are nearly impossible to fit my mattress. Very hard to attach when sheets are pulled tight enough.
