    May daughter has used this chair at her desk for two years. Since she is a teenager it has been treated pretty roughly and has stayed strong and sturdy. Absolutely no complaints.

  • Low end chair
    Verified Purchase

    This chair is definately on the low end of quality. Not much comfort and very little adjustment capability. Cushions are thin and firm. Assembly was easy, but came with extra bolts that left us wondering what they were for. Would be better off spending a little extra money and getting something that is better.

    This is an excellent product, especially for the price. Set-up is fairly easy and should take under 30 minutes. It has the feel of quality construction (in spite of its being made in China) and the seating is very comfortable. I especially like the back support. It does not tilt back very far, only a few inches or so, but for me, that is no big deal. Another fine product from Overstock.
