There was a time when the only sewing operator chair Reliable produced was a stackable wood/metal chair that sold for about $25.00. Back in the day operators would customize it with their own custom made cushion/pad to help make it more bearable. The idea of a chair that was height adjustable for a sewing operator was impossible. Today we have the SewErgo 100SE. It is an amply cushioned height adjustable made with 62% recycled polyester and is even Greenguard certified. Working properly and safely is simple with the use of glides. The glides work with the operator keeping them in place. Maneuverability is also easy when not seated. Now that s progress.
