These are great, took only 10 minutes to put each chair together. They were shipped very well and nothing was damaged. I got them in white and they look great, are comfortable and the hydraulics work well. I’m taking off one star because there’s nothing to secure the chair to the base; in the event the chair falls over the base may come loose. However, the base is nice and wide...and I don’t anticipate having that issue. Overall, definitely worth the buy.
