I would like to give my review of these seats. I ordered 3 seats from Stargate Cinema in Dec 2011. After 2 calls they finally decided to ship them in Jan 2012. When they arrived one seat had a bad motor so I called right away for a replacement. As of today haven't received it. There is a small PC board in the wiring harness and it was bad.
The seats are comfy for my 5'9" frame and my wife loves the fit also. She's 5'4". I ordered the seats as individuals and removed the arms for the configuration I now have. That way I have 2 extra arms for parts. We are getting butt marks in the padding and don't know if that is a sign of things to come. I only weigh 183lbs.
Because I removed some arms I was able to see the Chinese build quality and it is typical of what I see in everything built there. The holes are ground out if they don't line up. The bolts are cheap and the paint underneath looks toxic.They use stacked washers a lot also.
With all that being said, I can keep an eye on things and being a welder I can hopefully fix it before it goes bad.
