This is a very comfortable desk chair I bought for mufti-functions, unfortunately it did not meet all our needs.'
When assembling the chair all went well until we got to the two upper arm screws that would not engage no matter what we tried.  To this day they come lose and I try to find the inner set to re-screw...frustration.
The other issue was the narrative noting high back, it does not meet my 6 foot husband's upper back support (too low)
