I have an open concept living space and wanted to keep my dog out of the living room area when we're not in there.  It looks much better than other type options and serves its purpose.  My dog is only 11.5 lbs., and not aggressive - I think a larger or more rambunctious dog would be able to knock it over even though I bought 2 of them and overlapped so that I could do sharp angles for a more stable gate.
