Arizona’s Trusted Used Office Furniture Dealer

Fourth Addition has been helping Arizona businesses furnish their offices for less. We specialize in buying and selling quality pre-owned office furniture from the industry’s top manufacturers, including Herman Miller, Steelcase, Haworth, and Knoll.

Our mission is simple: provide businesses across Arizona with high-quality office furniture at a fraction of the retail price, backed by professional service you can count on.

What Sets Us Apart

Unlike big-box retailers pushing cheap, disposable furniture, we deal exclusively in commercial-grade pieces built to last. Every item in our inventory is inspected for quality and functionality before it reaches your office. When you buy from us, you’re getting furniture that was originally purchased for $500-$2,000+ per piece — at 50-70% off those prices.

Our Services

We’re more than just a furniture dealer. Fourth Addition provides a complete range of services to Arizona businesses:

  • Buy & sell used office furniture — We maintain a large rotating inventory and also buy furniture from businesses that are downsizing, relocating, or upgrading.
  • Delivery & installation — Our professional crew handles delivery and setup throughout Arizona, with free delivery available in the Phoenix metro area.
  • Space planning assistance — Need help figuring out how to configure your new office? We can help with layout and product recommendations.
  • Liquidation services — Closing an office or upgrading? We’ll buy your entire inventory and handle the removal.
  • Panel cleaning & refurbishment — We clean and refurbish cubicle panels, chairs, and other pieces to like-new condition.

Sustainability Matters

Every piece of used office furniture we sell is one less piece in a landfill. Office furniture is one of the largest contributors to commercial waste, and by choosing pre-owned, your business reduces its environmental impact while saving money. It’s a win-win.
