One of the things that undermines the used furniture market for higher-end furniture is storage. Larger pieces often get stored somewhere for a period before they're sold, but unlike veneered MDF, solid wood pieces are vulnerable to get warped by rapid changes in moisture, particularly if they get temporarily stored in non-climate-controlled storage facilities. I wonder if there's a business opportunity for some kind of efficient middleman that takes high end furniture off people's hands and stores it properly while facilitating resale.
