Office Master PTYM-XT was specially designed to suit extra tall users. As a member of the PT Value Line though, it still features many of the same great adjustments found amongst the other PT's. However, in addition, the PTYM-XT also offers dual-colored 65mm soft casters, a heavy-duty metal base, extra high 6" cylinder, a taller back, and a longer seat cushion that provides more support.
With all that it has to offer, it's no wonder that this tall person's chair is named after its inspiration, a certain slightly-taller-than-average Chinese NBA star! (hint: Yao Ming). PT Value Series designed to accommodate users up to 300 pounds.
