    Worth every penny...

    Posted by Jen on Jun 24th 2016

    The Neutral Posture Petite Ergonomic Chair and this footrest, the Humanscale FM 300B Foot Machine, have made an extremely positive difference. A decade of chronic pain from a back injury has completely changed my life. Nerve damage has affected both feet. Standing in place and/or being on my feet to walk short distances are extremely painful. Sitting for more than a few minutes equals torture. Every day. All the time. Products from The Human Solution have literally been THE FIRST things that have not been an absolute waste of my money. I highly recommend the chairs, desks, and especially this footrest. This respectable company will make sure that you order the right products based on your personal needs.

    Great foot rest

    Posted by Chris on Nov 25th 2015

    This foot rest is exactly what is says it is and fully adjustable. In order to adjust, simply unscrew the knob on each side and lift the frame, when you reach the correct height for you screw them down to lock it in place. The roller is nice for planters issues ;-) Very happy with my purchase and expect to be ordering a second one for the office.

    Love this product. I'm going thru Chemo and suffering the side affects of hand and foot syndrome. One of my bosses had this in his office and offered to let me try it and it superseded my expectations. Would definitely recommend.

    Awesome footrest

    I've tried a few of them and this is worth the money. The bottom it stays in place and the rocking motion is nice and subtle. High quality.

    FM 300B foot machine

    Posted by Skeptical on Nov 12th 2012

    Well, it came in the mail today with no instructions.

    And although the description says it's adjustable. It's NOT. It just rocks back and forth which is supposed to mean adjustable height? I think it's quite misleading.

    I bought this for my husband for Christmas.
    He likes it a lot. I like the cherry finish. It looks good in his man cave! We would recommend this machine!

    Very well designed and functions as represented.

    Love the way that it articulates and allows you to rock your feet back and forth.

    The only suggestion is that I would have the entire surface covered with the massage balls.

    Love the rolling motion - very comfortable positioning too. Highly recommended.
