    One of the best chairs!

    Posted by Susan on Sep 30th 2015

    After weeks of researching and trying out chairs at other office supply chains, I stumbled onto this website and found the chair I've been looking for! Even tho this chair is for "big and tall" people, I am of average height and weight and the reason I picked this particular chair is the seating is LONG enough where it will not cut off circulation to my legs.
    I ordered the chair on line and it came within 2 days and shipping was free as promised. The chair was a breeze to put together too...
    I've had it over a week now and it's VERY comfy with the larger seat which is adjustable and the thick foam padding of the seat and the back of the chair.
    I highly recommend this product...I'm just very pleased with the quality and can sit for long periods of time with no back ache, neck ache or aching legs....
