Slide Out Storage Tower by Jobar

Frederick M: Cannot stack. Good solid plastic construction. Using it for laundry items. For the price very acceptable.

Ellen B: I would only stack one on top of the other if i had light items on the top, and/or if there were walls or some kind of enclosure on either side. Works great side by side.

Sherri L: I'm pleased with mine. It functions as expected. It is rigid plastic, not flimsy, but certainly not heavy. It is designed to be stored in a narrow area, not free standing. It would not stay upright if subject to traffic, jostling, bumping, etc. It does stand upright while extended for access, it doesn't topple on it's own. It holds a fair amount. I have mine fully loaded and it still rolls easily. The shelves are not very deep, so again, it is not meant to be used as a free standing shelf, room divider, etc. It's just not designed for that. I do not think you can stack one on top of the other. It is certainly not designed to accomodate that. The top is smooth, there isn't enough surface area for a good connection, and the bottom is flat, with rollers. Additionally the end panels do not extend very high, so you could only put very short items on the top shelf, and it would be very hard to access anything there with a second shelf mounted on top. I suppose if you were very motivated to make it a double decker unit you could drill a hole in the top of each end panel on the bottom unit, and on the bottom of each end panel of the top unit and mount them together with a very small diameter dowel, but it would be a lot of effort for what I doubt would be a very stable configuration. You certainly could not support anything of significant weight in the top unit.
