<p>An infant car seat comprises a back support portion (2) and a leg support portion (4) which merge together at a junction region (6) and which afford respective retaining means (28, 40). Overlying the junction region (6) is a flexible contour modifying sheet (20) with engagement means (26, 34) at each of two opposed ends. The engagement means (26) at one end are inseperably engaged with the associated retaining means (28) whereby the contour modifying member (20) is not removable from the seat. The other engagement means (34) is selectively engageable with the associated retaining means (40) to tighten the contour modifying member (20) whereby the latter then extends between the two retaining means spaced from the junction region (6) and has a radius of curvature greater than that of the junction region.</p>
