I second the commenter who recommended "Baby Bargains". It has a good intro to kids' furniture lines.
Have you visited a quality children's furniture store? I'm not sure exactly where you're located, but there are two in the Chicago area that I know of: Lazar's in Lincolnwood and Lil Deb-n-Heir in Naperville. Both have been around for YEARS and have very knowledgable salespeople who don't pressure you. Even if you don't buy anything from them, seeing furniture in person is always helpful as you can see how sturdy they feel. Plus they carry a lot of really quality brands and can give you info about your options.
