An angle or wedge adjuster for reclining furniture is provided with a slide that travels along a rack and which is formed with a cam surface for controlling the position of a strut that engages the rack teeth and is pivoted to a lever, the angle of which is to be adjusted. The movement of the slide is frictionally impeded by a spring-loaded insert located between the slide and a smooth surface of the rack, one of these two sliding surfaces being formed on synthetic plastics material. The spring may be a metal leaf spring bowed downwards to engage a portion of the slide and having its ends sprung against projections that also retain the insert in the slide. Alternatively, this spring may be of synthetic plastics material with its ends made in one piece with the insert of the same material. Conversely, the spring may be bowed upwards with its center integral with the insert. As a further alternative, the insert may be a metal plate coated with synthetic plastics material, and the spring may be a metal leaf spring bowed upwards with its center locked to the plate.
