A plurality of links, including a first link and a second link, interconnect the seat support and the back support with the frame. The links support the seat support and the back support for movement between the seat position and the bed position. Each of the first link and the second link have one end thereof with an opening therein. The horizontal support member has an upper surface and includes two side plates. An elongated opening extends downwardly from the upper surface. Each side plate has a first guide channel associated with the first link and a second guide channel associated with the second link. A first pin extends through the first link opening and each first guide channel, and a second pin extends through the second link opening and each second guide channel.
