Eames DCM
I'd choose the Eames DCM. It doesn't take up much space, it's beautiful and iconic.

A dcm would definitely be a good choice. Although, Id love a cherner chair too

Hans Wegner ?
alternatively, one Hans Wegner chair would make an excellent choice too. Pricy things, but in a hallway, you ll only need one.

I'd also love to see a photo of your entryway.

In no particular order.
1. The Prouve Standard. One of my favorite chairs.

I vote for Wegner's Valet too

whitespike's right
an informed recommendation assumes information. otherwise we're offering solutions to an unknown problem.
what kind of tree would be suitable for my yard? what kind of shoes should i buy? what's the best soap?
the most insightful answer: it depends.
