Marshall Mattress takes great effort to take a more balanced, sustainable approach to manufacturing. All foam and latex upholstery products are CertiPUR-US® certified, that is rated as low VOC (volatile organic compound). Similarly, no PBDE (Poly Brominated Diphenyl Ether) flame retardants are ever used. All boxspring and foundation components are hand assembled with sustainable Canadian wood products. To date, all Marshall bedding is produced in a focused, non-piecework environment where the staff works together as a team to offer a great night’s sleep, one pocket coil mattress set at a time.
