I had hoped the base of the chairs would be heavier to make them more secure. The chair does not screw  into the base it sits in the base. One of the chairs the stitching iis unraveling but it is double stitch so I believe it will be ok.  The material is soft, the cushion is good and the hydrolic pump is great you can adjust the chair  to any height.  I will keep the chairs because they won't get heavy use but if your planning to have a lot of traffic these may not last long!

Pros: Boxes are light, easy to assemble (3 in 30 min), nice color, fabric, hydrolics and swivel.
Cons: Stitching may not last, base not sturdy causing slight wobble, foot rest doesn't extend out enough.
