there are three sizes of aeron - on the top back under the lip feel and there are dimples - one for small, two for medium and three for large chair size
i’m 5’ 10 and the medium fits me great, just get it adjusted right and you can also flip the lumbar over to have two levels of lower back support (pull it up and off the chair back and flip it over - you can see there are two “depths” then slide it back on)
only people i’ve heard of that really did not like the aeron’s in our previous office of 100+ were people either too big or too small for the medium sized chairs we had
Looking for good lower back support. Tried the Aeron chair for a while but hated it. Anything people swear by in this industry of sitting? Have a reasonable budget for something well-built.Â
