      Fantastic! Allowed me to continue in my corporate position, all while managing severe lumbar pain before surgery.

    • Amazing chair
      Verified Purchase

      We bought 2 of these - one for myself and one for my husband. We sit all day at work and this is nice to switch out with a regular chair. I have had several co-workers laugh, then try the chair, then order one! Great price, easy to put together, very stable and extremely comfortable.

      I had the soft "closed-cell" cushions replaced with Confor foam -- much better.

      It was pretty much easy to assemble, though one part did not match the photo on the instructions. I use it several hours a day at my computer and it keeps me from sitting on my feet. It is easy to roll on carpet. In time I will know if it helps with alignment (I have tilted pelvis that needs adjustment frequently, along with lower disc damage).

      Verified Purchase

      I spend about 8-9 hours a day, sitting on 3 pillow on an old chair, writing by hand and on computer researching. I one of these chairs years ago. Now, I have another (am sitting on it now). I cannot praise this invention high enough. Easy assembly, instant comfort on the lower back, increased correct posture.The price at Overstock cannot be matched. I saved quite a bit compared to almost identical ergonomic knee chairs at outrageous prices. Thank you.

    • Great chair - very comfortable
      Verified Purchase

      Don't knock this until you try it. I have a really bad back. This is very comfortable & feels good. I like how it will slide all the way under the desk, and out of sight, in our new kitchen in the office area.

    Questions & Answers

    • Q:

      "Why did you choose this product?"

      • A:

        I purchased this because I have had a similar one in the past. I suffer from terrible back pain when I sit at the computer for longer than a few minutes. These chairs completely alleviate the back problem.

        Trying to prevent back problems.

      • A:

        Because your description was comprehensive, and I vigorously searched for a good value in a knee chair. I weigh nearly 250 lb so that ruled out many that had lower capacities.

        Previously used this chair type. Improves lower back and posture.

      • A:

        Recommended by friends for office work

    • Q:

      "Is this big enough to support a 6'1", 210 lb man comfortably?"

      • A:

        Yes, but seat tilts to the side

    • Q:

      "I just bought this, but was alarmed by the Prop 65 warning. Can someone tell me what it actually means with regard to this chair? Thanks!"

      • A:

        Thank you for contacting us, tbf. This is only in relation to California residents. The Prop 65 warning state that: The Safe Drinking Water and Toxic Enforcement Act of 1986 requires that the Governor revise and republish at least once per year the list of chemicals known to the State to cause cancer or reproductive toxicity. The identification number indicated in the following list is the Chemical Abstracts Service (CAS) Registry Number. No CAS number is given when several substances are presented as a single listing. The date refers to the initial appearance of the chemical on the list. For easy reference, chemicals which are shown underlined are newly added. Chemicals or endpoints shown in strikeout were placed on the Proposition 65 list on the date noted, and have subsequently been removed. Please let us know if you have any further questions.

    • Q:

      "How exactly are to sit on this? Can you send a picture?"

      • A:

        Unfortunately, we do not have any additional images of this product at this time. You sit on the upper portion of the chair with your knees placed on the lower portion and your legs tucked back underneath your body.
