question:
This item does not heat despite being turned on. In addition, the rack was nearly impossible to put together to be free standing. The provided screws were too big for the holes. Terrible product! To top it off it had absolutely no instruction on how to put together as freestanding.
answer:
negative

question:
This chair was quick and easy to put together. Not only were the bolts well packaged they were clearly labeled to avoid any confusion and came with a few extras. The chair is comfortable with a mesh back that allows support without being hot. The lumbar support helps make this chair more comfortable and there is a padded headrest if you just want to lean back and watch a video for a bit. Overall, very affordable and quality built office chair. I'm happy with this and do recommend it.
