Abstract
A sofa sleeper having a foldable bed frame connected by a collapsible frame support linkage with a sofa frame. The collapsible frame support linkage includes a novel styling structure that permits the pitch of the seat, when the bed frame is in the sofa position, to be adjusted as desired. This styling structure, in preferred form, includes a styling link incorporated in the collapsible frame support linkage that cooperates with a vertically adjustable styling bolt mounted on the sofa frame. The abutment position of the styling link against the styling bolt, which position depends on the vertical location of the styling bolt relative to ground, determines the collapsed position of the collapsible frame support linkage, thereby establishing the seat pitch of the sofa.
