Hey, I think selling old furniture is one of the toughest tasks because most of the furniture is too heavy to ship. Online classified sites are one of the best sources to sell your furniture easily. I can assure you because I had sold my office furniture recently. First I had planned a lot where to sell, when to sell, and how high I should set the price. Then one of my friends recommended a company which buys used furniture with the best deals. Its really tension free process and one can get good amount from it. I will suggest you to check out these types of companies at your place if you haven't sold them or maybe next time when you need to sell some furniture.
