    • Good for a second chair

      The seat is a bit slippery so I'm always sliding forward. It's great if I've been sitting in a regular chair all day, but it is a bit hard on the knees for long-term seating.

    • helps relieve back

      Was having low back ache and work at desk made it more painful. Now, can do work at desk and no pain!

    • It's alright, for the price.

      As others have mentioned in online reviews, the seat cushion angle is not ideal - it is a little flatter than what one expects on a knee chair. However, I haven't found this to be a problem for myself, yet. Also, as others have noticed, the height is a little low. This also isn't a problem for myself at 5'8". But, anyone taller than myself may have issues. Be sure to read the reviews on Google Shopping instead of relying entirely on the reviews. While the deficiencies are acceptable to me given the price I paid, I can't help but wonder whether I should have applied the funds to something more costly - even a HÅG Capisco or a Swopper. I could recommend this chair as long as the recipient of that recommendation recognized the caveats I've detailed above. The assembly was easy. One thing to note is that the instructions identified two small screws and two medium screws (in addition to the obvious two large screws). In actuality, there are four small screws and two large screws. There is no distinction of a small and medium screw among those screws provided.

    • Perfect for us

      Decades ago I tried an office mate's $250 "kneeling chair" and have wanted one ever since but refused to pay so much. About that time, a friend bought a no-frills model for ***; I tried it and unfortunately broke it. Recently I bought one in between (and a rocker) at a thrift shop for ***, but my shins ache when on it for a half hour. I decided I really want a comfy one with casters and height adjustment and would pay up to ***. Not finding one locally, I found this one, priced reasonably even before the coupon, bought it, and am very pleased with fit, adjustments, and comfort (I guess attributable to the memory foam). My only regret is that I waited this long. I've only had it a few weeks. I hope it lasts forever like the traditional office chairs I've used.

    Questions & Answers

    Get your product questions answered right here.
    • Is this big enough to support a 6'1", 210 lb man comfortably?

      • Yes, but seat tilts to the side

    • 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!

      • 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.

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

      • 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.
