SONGMICS Metal Folding Luggage Rack

Folded flat they slide right under the bed, but the real win is how stable it stays with a heavy suitcase resting on it. The black finish hasn't scratched despite being dragged across the floor a few times.

The steel frame feels rock solid under a fully loaded suitcase, and the folding mechanism clicks shut with zero wobble. I keep one in the guest room and one by my closet—having both for the price is a steal.

Finally got rid of the pile of clothes on the guest room chair. The folding mechanism clicks into place easily and the whole thing holds my fully-packed carry-on without any wobble, even when I lean on it.
