A cover assembly for the bed of a pickup truck including a rigid cover which is mounted to the bed by four spring-loaded arms which allow the cover to be moved vertically relative to the bed. The spring-loaded folding arms have arcuate bearing heads which minimize spring distortion when the arms are in their folded positions and have an improved locking arrangement for selectively securing the arms in their extended positions. The folding arms also have reversible mounting brackets which provide stabilized mounting thereof on the bed of pickup trucks having variously sized upper ledges.
