We bought a sectional. It's being delivered on Saturday:
http://havertys.com/furniture/reynoldsWe have a dining room table that we bought from Amazon with cheap chairs from Amazon (they stack for less space occupied when not in use) and we built a L-shaped bench. Came flat-packed and built inside.
In the kid's room, we have a dresser, desk, 2 wall cabinets, a tall shelf, and a pull-out sofa bed. All built in the room. Fortunately it's a toy hauler with garage door if I ever have to yank any of it out.
So long as you can get it through the door, there's no issue with residential furniture!
