A folding seat/table arrangement has transverse seat members (10,12) and transverse backrest/table top members (14,16) carried on transversely-spaced folding frames (18). In those frames, backrest supports (34) are pivotable relative to seat member carriers (30) between first and second stable end positions, by virtue of connecting links (38) which connect said supports (34) to rear seat legs (24). In one position (as shown) the backrest transverse members (14,16) are supported as an upright backrest for seated persons. In the other position, the backrest transverse members (14,16) are supported by props (48) from rearwardly-inclined backrest supports (34), in a horizontal table-top posture.
