The design is embodied in the chair. The first tube bundle includes a plurality of tubes extending substantially horizontally in the shell. The housing includes first and second wire receptacles that include first and second dielectric shells, respectively, and first and second contacts, respectively, that are held by the first and second dielectric shells, respectively. A metered dose of the composition can be sprayed on a topical site to form a stable, breathable film, preferably over a fixed surface area.
