I need to exchange this chair for another.  I am 77 years old and have many problems with my legs. They need to be elevated often.   I cannot put enough pressure on the return mechanism to get the chair to return to the regular sitting position and thusly have difficulty getting up.. This problem has caused me much consternation. I like the looks of my chair. It goes well with my room, but I cannot use it. I really would like to exchange it.
