If you are large and need a chair, or want to have an option for your obese friends and/or family members. I highly recommend
Koolest Products. I got their Maxx Daddy chair. There was a problem with the foot rest. After I had used it twice, the rivet wore through the strap. I communicated with their customer service department and they are sending me a new footrest at their expense with an improved device so the problem will not recur. The woman communicated with me almost as fast as IM'ing, and I just got a notice that the footrest has been shipped. Is that cool, or what?! Please check out their products. It's not often that there will be a company that will serve the needs of both average and obese folks.
I own the Maxx Daddy, with a capacity of 750 pounds. It's a great chair!
