Yes, that is how I have mine, but it is in a corner. I am not sure how sturdy it would be completely free standing.

Yes, but one will be missing a panel. I did this, but left the bottom panel empty. It works just fine.

Yes, you can stack them any way you like. They are pretty flexible that way.

I couldn't find anywhere to purchase just the risers, but you can stack the four you get together.

Somewhat. They dont fit all the way down, but I do stack mine...but only a couple at a time. I think all of them together would make them topple over.

Hi, you can't stack them. The posts are only tall enough to accommodate the height of the boards, 3 for the taller one, 2 for the shorter. Plus you only get two posts for the shorter side so you'd have to make 2 more shorter ones somehow. You can connect multiple kits next to each other but not on top of each other.

You can stack them vertically if you want. It would be less stable, so you would have to put your heavier items on the bottom two shelves and your light items on the top.

You can stack them. I have more than 3, but they don't "nest"; they do kind of fit inside each other so yes, I stack them.

Yes, it's possible but it may not be as sturdy as you would like in child's bedroom. I would limit the stack to three and that might defeat your purpose of vertical space.

Yes, they will nest together for stability. I have not attempted to stack them, so I don't know if that would be advisable.

That really depends on how high you want to (or physically can) stack them. I would limit it to three...it would be too difficult for me to stack any higher than that. If you are tall and strong, you could probably do four.

Unfortunately, you can't (at least not without modifications). The metal rods that support the corners are topped with rounded caps and the bottoms have plastic hexagonal "feet" that wouldn't fit together if you stacked them.

I don't think so. These three galvanized boards are about 1/2" or more thick. You could stack them vertically.

You can but I don't think it's a good idea considering the strength of the stand. It's not a very sturdy one. Secondly, you would not be able to cover it if you stack two. Hope this helps

They can probably be stacked, but I don't know how stable it would be. I only bought one, but I really love it.

Haven't tried with 4-unit high. Yes stackable. Stability may depends on the weight of your content, e.g. books are heavy, should be on lower cubes. You can try with 4-unit high 1-unit width, if it works for you, get more units and change configuration to 4-unit high 2-unit width.

Yes you can. I also had a space that was just a little too small so I left off the bottom legs and just used the first level as the base and stacked the second one on top. It worked perfectly.

No, you can't stack them unless you come up with some creative way to do it yourself. No gizmo included in the package.

Actually I believe you can stack as many as needed, there is a cap for each corner if you are done stacking on top. Though each set has feet so you may be able to only have that one set (on bottom) use the feet.
