Well-built and comfortable

from VC Highlands, NV – Verified Buyer

I had a well-known brand chair for many years, but had many problems with it. Quite frankly, the build quality wasn't there and the poor quality bolts that held it together kept breaking. Finally, the frame developed a crack that threatened to dump me on the floor. I'm tall, but not heavy, so it's not like I put too much stress on the old chair. This new chair has very heavy duty construction and I can't imagine it breaking. But even better, it's very comfortable, too.

Great for bigger guys and painful backs

from Elgin, IL – Verified Buyer

We got this chair because my husband is a bigger guy at 6'4 so we needed something that would stand up to his weight and to not be sitting on the floor when the chair was at it's highest. He loves it. I love it due to the back support as I have bad posture but this helps my lower back stay straighter and I'm not slumped over right away. Loved this purchase!

Pleased with purchase

from IL – Verified Buyer

I needed a relatively inexpensive, good quality office chair to replace the old one which was bothering me. The best compliment I could pay would be that I no longer thing about my chair while I'm working.
