Claim (Index 9):
A footrest stretching device of a convertible sofa, comprising an inner footrest, a middle footrest, and an outer footrest, the middle footrest and the outer footrest linked to one another in a telescoping manner such that a gap between the middle footrest and outer footrest varies as the footrest stretching device moves from a retracted condition to a reclined, extended condition, and the inner footrest being mounted on a mounting member that is pivotably and slideably engaged with one or more links associated with movement and support of at least one of the middle and outer footrests, wherein in the retracted condition of the footrest stretching device, the inner footrest is tucked behind at least one of the middle footrest and the outer footrest, and when in the reclined, extended condition, the inner footrest is substantially aligned with the middle and outer footrests, with a gap between the inner footrest and the middle footrest.
