Yes, our line of contract furniture has been designed and tested to ASTM* commercial standards. Our commercial seating products are rated to 300 lbs. *Grosfillex was part of an ad-hoc task force that worked with the American Society for Testing and Materials (ASTM) to develop industry standards for plastic chairs designed for outdoor use. These quality and safety performance standards were first published in 1994. All Grosfillex contract chairs meet or exceed these industry standards. Further, Grosfillex designs, manufactures and markets all commercial grade resin furniture with the ultimate consumer's safety in mind.
