Please Note: Additional COM/COL is required for TB-133. Please send in COM/COL requirements for seat/back cushions and the back shell.

The chairs presented within this price book, unless otherwise specified, do not meet California Technical Bulletin 133 (TB-133).   Most via seating chair models can be prepared to meet the flame-retardant requirements of California Technical Bulletin 133 (TB-133) and the Boston Fire Code. In order to comply with these fire codes, via seating must upholster the chair with a flame-retardant
material (i.e. Kevlar® or equivalent). Additionally, most plastic components (i.e. seat pan, back shell, shrouds, etc.) must be either removed or completely upholstered with a flame-retardant material.

Please note, any chair models specified to comply with TB-133 may not resemble what is photographed in any of our marketing materials after the above mentioned modifications have been made. via seating is not responsible for determining the requirement of TB-133 compliance. Check with your local building departments to determine if TB-133 is required on your order. To specify TB-133 on via seating chairs please refer to the pricing pages within our price book.
