Claim:
A load support structure comprising: a pair of laterally spaced beams each comprising first and second beam members spaced apart in a vertical plane and forming a gap therebetween, wherein said first and second beam members each have a horizontally extending portion and an upright portion, said upright portions defining a backrest support and said horizontally extending portions defining a seat support, said first and second beam members comprising a first material, wherein each of said first and second beam members experience elastic deformation through bending as said beams are moved between an upright position and a reclined position; a plurality of linking members bridging said gap and having first and second end portions coupled to said first and second beam members, wherein at least some of said plurality of linking members comprise a second material different than said first material, and wherein said at least some of said plurality of linking members are put in tension as said beams are moved from said upright position to said reclined position; and a flexible membrane coupled to and extending between said first and second beams, wherein said flexible membrane defines a body support surface.
