The load support member includes a beam member, a coupling member, and a stopper member that are spaced apart from each other. In another feature, the beam has a support surface, the support surface defining a first land portion and a second land portion, wherein the land portion is in contact with the membrane. The membrane is supported. In another feature, a reinforcement member is mounted between the transversely spaced beams, the reinforcement member having a height that is greater than a width at the end and a width at the middle portion. Is longer than the height. In another feature, a pair of armrests are releasably engaged with the crosspiece and the integrally spaced beam. In yet another feature, a pair of beam members is fixedly coupled to the crosspiece, the crosspiece is pivotally coupled to the link, and the link is pivotally coupled to the beam. A method of assembling a load bearing structure is also provided. |
