Product was well packaged in a sturdy card board box by the manufacturer (Union & Scale) care was taken to protect all of the sharp corners of various parts by wrapping them with a thick cardboard. Most of the parts are made out of thick molded plastic which is very sturdy. The only parts I believe are hard metal (Steel) is the controller and the arms assembly and the control cylinder that go underneath the seat. The Instructions are very clear and concise and all of the hardware (screws) are color coded and packaged well in separate pouch which makes it a breeze to assemble (Took me 45 minutes to assemble). The only tool I needed was the Allen Key provided with the hardware to assemble the entire chair. The chair has good amount of movement up and down and back and forth. The head rest can be tilted to a good extent to provide that extra support to the back of your Neck. The Lower Lumbar support is at the right height and can be moved up and down by a few Inches which helps position it to user’s needs. The arm rest moves up and down by quite a bit. The arm rests are just soft enough that you will be able to comfortably rest your arm for the entire day and are designed to be wide enough and located at the right height in its lowest setting that it supports your arm well when using a keyboard or Laptop on a desk. I am 6 foot tall and athletic all the adjustments fits me in the right places at it lowest setting just to put things in perspective. The mesh on the seat the back and the head rest seems to be sturdy and well woven with a good material of the right gage. A bit of cushioning is provided underneath the mesh for the seat at the front where the underside of your knees rest and the lumbar support no such cushioning is seen on the back or on the head rest which is understandable. There is good depth to the seat so that you feel well seated at all times. The seat to the control cylinder and the control cylinder to the base of the legs is a soft assembly (i.e no bolts hold this together) The top and bottom of control cylinder sits in a hole on either side one in the control arm assembly under the seat and the other in the center of the leg. So just right after assembly if you hold the seat and lift the chair the seat might separate out from the cylinder (you can put it back in seconds not a big deal) but after some use I have tested this and they seem to stay together when you lift the seat to move the chair. Highly recommend this chair.
This chair is incredibly comfortable and reasonably priced. My college student son spends many hours in this chair daily between remote classes and gaming. I got a second one for myself for my home office because it’s so nice. Setup is fairly simple too.
