Chair for use in a clean room environment

Abstract

A chair is provided that is specifically designed for use in a clean room environment by limiting the emission of particles by the chair as clean room personnel alternately sit down and stand up. The chair includes a base and a seat member operably mounted upon the base. The seat member, in turn, includes a cushion and a shell encapsulating the cushion. The shell is comprised of polytetrafluoroethylene (PTFE). By encapsulating the cushion, such as a foam rubber cushion, in a PTFE shell, the chair limits emission of particles by the cushion.

That which is claimed: 
     
       1. A chair adapted for use in a clean room environment, the chair comprising: a base; and   a seat member operably mounted upon said base, said seat member comprising: a cushion; and   a shell encapsulating said cushion, said shell comprised of polytetrafluoroethylene to limit emission of particles by said cushion.
