They've got shelves in many different dimensions, and it's really interesting how they work - you snap a plastic clip on each post where you want the shelf to sit, meaning you can adjust the shelves to any desired height in 1" increments along the posts. So flexible!! You can build the shelf to be a specific height for one use, and next year decide to change it up and use it in another way! You can even have the poles custom cut to a certain height. We had one of our sets cut to fit our garbage can under it (seen below left). So that we could keep it open at the front, we ordered 1 hanger rail for width and 2 hanger rails for depth. These allow the lowest shelf to be raised without losing stability.
