The chair is almost perfect. Although I initially wanted to give it a 4-Star Review, I can't deny it deserves 5-Stars. I've had the chair for a few weeks. It was delivered faster than expected.
My only dislike is that the mesh on seat could be tighter. In the photos I share, you'll see the mesh on the seat can fold over a little, when I'm sitting in it. It's not a significant issue at this time, but I'll have to see how well it holds up after months or years of use. This is the 2nd time I've bought an ergohuman chair. The first one I had, was leather instead of mesh but I had to part with that model when I moved into a new place. So I wanted to give the mesh chair a try, seeing that the leather, older model wasn't as adjustable as this newer model.
Other than the loose mesh on the seat, the chair is TOP NOTCH. I love the chair. It's super comfortable and highly adjustable to accommodate people of all sizes and body shapes. I'm only 5' 2" tall and it's extremely hard for me to find a chair that doesn't hurt my knees, since most chairs are designed for average sized people and I'm a shorter than the average person. Being able to adjust the position of the seat and the arm rests, in the ways this chair allows me to, makes it a top tier QUALITY office chair.
I sit at my computer desk for long periods of time, so I needed something that I can feel comfortable in and this chair is very comfortable... I absolutely love how adjustable it is and I love the mesh overall. When the weather is hot in Australia, I can just put a fan behind me and feel the cool air, through the chair. No more sweaty back; no more sweaty bottom! The mesh is functional in hot climates.
Also, my arms are shorter in length, because I'm short, but this chair has the most adjustable and comfortable arm rests that I've ever experienced; I am happily thrilled about the adjustability of this chair. I love this chair and I now look forward to sitting at my computer desk that I have my chair adjusted properly.
One of the best things about this chair is that if any part breaks, I can buy replacement parts for it, right on their website. My particular model: "Ergohuman 2 Elite Platinum Mesh" did not come with a leg rest, but from what I understand, I can order the leg rest separately and install it myself later, which I plan to do eventually.
I've sat in this chair for hours at a time and have almost fallen asleep in it, because it's so comfortable. I'm certain that if I get the leg rest for it and I lean back all the way, I will easily be able to sleep in it, if I want to.
Despite the mesh on the seat not being as taunt as I think it should be, everything else about this chair is 5-star quality. It also looks very stylish at the same time. If you need a good office chair that you'll need to sit in for long periods of time, don't hesitate to buy this chair today and give it a try!
