Brand New World's Enviro-Child Upholstery offers early childhood classrooms an eco-friendly and healthier upholstery alternative that is as durable and easy to clean as vinyl. Made of polyurethane, it is PVC-free. Plus, it features an antimicrobial finish that inhibits the growth of bacteria and viruses. These units sit directly on the floor with 1/4" gliders/legs. With a seat height of just 7.5", it's a "perfect fit" for toddlers aged between 18-36 months.
