When I was buying the furniture for Zadie's nursery, I couldn't let myself buy a regular changing table. It was hard to find anything attractive for less than $100. A lot of the brands weren't even made of real wood. Also, once your kid is potty trained, you have this odd piece of "wood" with no other use.
So when I saw the Trofast system at Ikea, I did some measuring and came up with this idea. We bought the stair-step piece and the single unit. Mr. Lemon cut a piece of plywood 1" larger than the changing table pad. I had some teal fleece in a bin so I cut it to size, wrapped it around the plywood and stapled it to the plywood like I was stretching a canvas. So the staples wouldn't scratch the Trofast pieces, I used double-sided tape to put a layer of felt on top of the staples. Mr. Lemon was concerned about safety so he somehow attached the two Trofast pieces together (leaving enough distance between them so that the plywood would fit nicely).
This has been working great for us. The Trofast system is the same size as a standard changing table and doesn't kill Mr. Lemon's back like the pack n play does. The best part about this is that when the baby's no longer in diapers, we'll have a great storage system for all her stuff. If we're lucky, she won't crack her head too many times while she's climbing all over it.
I have more pictures of this system and the nursery over on my flickr.
