Big and tall chairs are designed to accommodate users that are over 250 lbs or over 6’4”. These large chairs are also known as big man chairs. Chairs for the tall have high backrests and usually feature a slightly higher seat height adjustment range compared to standard office chairs. Chairs for the big will often be wider in design with thicker padding. All big and tall chairs will feature a stronger chair design, with more durable chair frames, bases and casters. If the big man chair has armrests, then they will most likely be oversized and reinforced for the added weight that will be placed on them.
