I’m a 510 fit 180 pound guy. I decided to write this review after one of my 4 hour online classes as I noticed myself getting uncomfortable with a few things. The armrests are completely without function, the reason being Is that they rock hard, narrow, and at an angle so your elbows are always the point of contact. The seat of the chair is a tad too long which ends up digging into your legs and puts pressure on your lower back if you need the chair up high so it forces you to lower it so your legs are grounded and flat. Overall I find myself stretching every ten minutes still as I feel  pressure on my lower back because of the inadequate padding which is purely form over function. The chair is attractive, well made, and will last quite a while but, I think I’ll be passing it off to get something more on the plush side.
