start with the top piece as shown. bottom of each piece is indicated with tap and top sides have a rounded edge

Insert the top mounting bracket as shown and do not over tighten or the shelf will not swivel.

insert the center pipe underneath the top shelf and again do not over tighten.

this is how your piece looks once you insert the center pipe.

line up the top of the lower shelf flange to the center pipe. And swivel it onto the pipe again just loose enough to swivel.

final step is to do the same as the first step with the bottom piece. Hang up your shelf and send me a picture of your plants on it 🙂 thanks again, Lew
