I got tired of fitted sheets slowly slipping loose at the corners, and I didn’t love the usual solution with elastic straps that have to be pulled all the way under the mattress. So I tried a simpler approach: I mounted suspender clips permanently under the bed frame to hold the sheet in place.

The setup is just short (fabric) elastic bands with strong clips—one end is screwed to the underside of the bed, and the other end clips onto the sheet near the corner. Everything stays hidden, and you can clip the sheet tight in a few seconds when making the bed.

The best part is that it works with any fitted sheet without adding straps to each one. Sheet changes are quick (unclip → swap → clip), and the corners stay tight without extra elastic running underneath the mattress.
