I have 24 bed risers. They are very sturdy and provide lots more storage under your bed. I thnk they are about 5 inches tall. They have an indention in the top for the bed wheels to go so they stay in place. You can buy 4 for $5.00 or $1.50 each. You can buy as many or as little as you want. First come first serve. I won't hold items. Thanks Location: Meridian it's NOT ok to contact this poster with services or other commercial interests idaho
