We've bought furniture from Green Front's Manassas location (http://www.greenfront.com) as well as from The Keeping Room in Alexandria (http://www.thekeepingroom.com).

Green Front usually buys their pieces from the trade shows and sells them at a discount. The service is decent and the selection is quite varied. If what you want isn't on the floor, then take the ticketed price on a similar item and add 20% for a ballpark figure. Delivery charges are based on destination ZIP code and number of pieces delivered.

The Keeping Room is a small family owned business. The proprietor, Duane Collie, specializes in Taylor King, Hancock & Moore, and Bradington-Young upholstery. (All very fine furniture makers.) He knows his product inside and out and customer service is top notch, although his floor space is limited (i.e. you probably won't be able to sit in it before you buy). His prices are extremely competitive. Local delivery for a flat fee.

Another furniture shop that I've heard good things about is Annie's Fine Furniture in MD (http://www.anniesfinefurniture.com). They also sell Hancock & Moore and Taylor King, I believe.

Good luck!
