For constraint purposes, this prototype is demonstrated with 2 stuffing contraptions over a bar and using a pillowcase. The real product would come with 2 more identical pieces (one for each corner of the bed frame) and would be used with bed sheets.
As you can see, you simply align your sheet over the bed frame and then then stuff each sheet corner in the devices attached to each side of the bed frame. You can stuff as much or as little as you like, depending on how taut you want the sheets to be. These prototypes were attached to the bar using duck tape, but the real product would use an adhesive putty or strip to securely stay on the bed frame without causing damage.
