Professor Ergo's Thoughts:

Heavy-duty chairs usually come at a steeper price than their "regular" chair counterparts. This is because they require more construction materials in order to meet certain benchmarks. The Office Master Maxwell Heavy-Duty MX84IU Chair is a budget-friendly heavy-duty, intensive use chair that can support up to 400 lbs. This makes it a great option for people with heavier body types looking for ergonomic comfort.
