It’s a nice little printer stand, able to hold 2 decent-size printers in a small space. Assembly was fairly easy with extra screws and dowels included. The only thing that is weird is that each shelf is two pieces and they have to be attached together with dowels and then supported on the edges with metal bars. All of the metal support bars are also two pieces and have to be attached together before attaching to the shelves. The only reason I can see for this is so they can use smaller shipping boxes. But once it’s assembled it feels sturdy enough.

It had the features I wanted at a reasonable price

Size: 22"×15", Color: Black

I needed a new printer stand and I looked at many before I chose this one. I liked the size of it for my apartment and that it had shelves for additional storage. I was able to put it together without difficulty. It is sturdy and was a good price. A plus was the power outlet and that you could add wheels or make it stationary. It goes well with my computer desk.
