Hi all! I'm seeking information and opinions about a potential purchase.

Our apartment is kind of lacking closet space (no surprise, it is NYC after all) and I was considering getting something like this to help handle the overflow. tinyurl.com/b7wbk7

Has anyone here ever had one of these or something similar? Are they reasonably stable or pretty wobbly (they'd be on a wood floor, not carpet). We also have curious cats; If a cat tried to climb one would it tip? The tipping over factor is my biggest concern: I don't care if it's perfect, I just want to make sure we won't come home some evening to discover the cats have tipped it over and smooshed themselves ...

thanks!
