"Doesn't this sort of look like that one thing in the DWR catalog?"
I live near an IKEA. I'm not too far from a couple DWR showrooms as well. I spend hours and hours paging through the DWR catalog when it comes in the mail. Considering my "knowledge" of both, the one thing about IKEA is it's so easy to spot their furniture, especially when you walk into someone's house/apartment and it looks like a page out of their catalog or like one of their showrooms.

When I'm at IKEA, I'm always on the lookout for that special piece that doesn't scream, "I'm an IKEA product!". Every once in a while, you'll find something. With that in mind, how often have you walked through an IKEA store saying, "doesn't this sort of look like 'that one' piece in the DWR catalog?"
Anyhow, here's some similar -- and not so similar -- products from IKEA and DWR (none of which are part of my personal collection):
