After almost a year of working from home due to COVID my lousy back/neck/shoulders were really suffering & I was getting headaches regularly by the end of the work day. This chair was a great investment and is enabling me to work w/o discomfort.
I was looking at an Aeron chair and had one at a former office space....but too spendy. This is really great comfortable very adjustable and went together easily! I'm tall and thin was worried it might be good for my form factor but it is fine.
For reference I am 6'1". I bought the Dexley over the Hyken for its larger size thinking it would work for my height but the bottom of the headrest rests against the top of my shoulders. The lumbar support at its highest setting is still an inch or two too low and puts pressure on my lower back instead of providing lumbar support.
I'm still bothered that my previous chair Staples "Montbrook" only lasted three years and when I brought it into the store to show the manager there was apparently nothing that could be offered in terms of a reduction of price for the new chair I had to purchase. The interior cushion on the Montbrook had deteriorated to a point that there was very little cushioning left. This chair should have lasted more than three years.
Sitting in this new chair my back requires I stand up less often than in my previous chair. The only improvement I suggest is that the lowest setting of the arms be a bit lower.
