Abstract
Abstract A stool upholstered with a protective stool cover, and related objects are shown. The cover comprises a seat encapsulating, cover material, the lower edge of which is attached to a seat pan covering, shaped wall profile which protects against inadvertant, cover material damaging impact against the seat pan. The profile also eliminates the discernment of outlines of the edge of the interface between the seat pan and the cushioning material through the covering material. The profile includes a flange section adapted for attachment to the lower side of the seat pan, which extends at substantially right angles from one end of the seat pan edge covering collar section, as well as a seam section adapted for sewn attachment to the covering material. The seam section is offset and extends from the other end of the collar section, parallel and adjacent to a line of extension therefrom.
