A canopy device includes a canopy membrane, first and second engagement members configured for being releasably securable to a chair, and first and second pairs of posts. The first pair of posts has first ends independently pivotally coupled to the first engagement member and second ends coupled to the canopy membrane. The second pair of posts has firsts ends independently pivotally coupled to the second engagement member and second ends coupled to the canopy membrane. The canopy membrane is reconfigurable from a collapsed configuration to a deployed configuration as the second ends of the posts are pivoted away from each other.
