Make sure you can get furniture through the door

I live in an old apartment building in Washington DC. We bought a nice sofa and literally could not get it in our living room. The hall way made a sudden turn and no matter what we did we couldn't get it in.

Crate and Barrel were pretty understanding but I am not sure other stores would be. You other post at http://www.millennialliving.com/Activities/Renovation/stairs-doors-furni... is a must read, especially if you live in an apartment in the city.
