Abstract: A bonnet for lawn chairs and the like involves a canopy formed of a plurality of flexible, resilient bows, which are maintained in a generally U-shaped configuration, and a flexible covering attached to and interconnecting the bows along a substantial portion of their length. The bows are attached to a chair through two bow assembly bars, each of which have a separate attachment location, in linear spaced relationship, for each bow. Each bow is pivotally connected, with adjustable tension, at its ends between the two bow assembly bars at the separate spaced locations so as to permit each of the bows to be individually pivotable, fore and aft, thereby permitting variation of the canopy coverage and location. The bow assembly bars are removably clamped to the framework on opposing sides of a lawn chair. A flexible line, of less length than the bows, is used to directly interconnect the bow assembly bars so as to restrain the resilient bows to a generally U-shaped configuration.
