It folds flat, which is what separates this from the fixed ladder stands - it goes behind a door over winter instead of taking a corner of a room. Three open shelves hold 33 lbs each on a frame measuring 27.5 x 15 x 37.5 in, weighing 7.5 lbs in bamboo. The open sides let light reach plants at the back of each shelf rather than only the front row. Bamboo resists the damp that gathers under a watered pot. It works indoors by a window or outdoors on a covered balcony.
