These chairs are great. The mechanism to swivel the chairs gives a smooth ride when turning. The padded seat and back are really comfortable.  The distance between the seat and and foot rail is set so your feet are comfortable.  The downside.  Each chair has 20 screws to assemble.  The all purpose tool they give you will not make it for assembly.  You need your own screw driver with a hex nut assembly.  Also when assembling the the rotating mechanism to the seat side (there is a top and bottom assembly.  Bottom attaches to the legs, top to the seat) my wife had to attach the nuts to the screws because the spacing was so small I could not get my hand in place to thread the nut.  Make sure someone is available for that job.  It really is a 2 person operation to assemble.  But as I said once complete the chairs are comfortable and we love them.
