The early reviews are in.


This chair feels amazing, the cushion is so comfortable. I was very surprised with the arm rests and lumbar support, they are so supportive and I like to rest my arms on them while I'm typing. It takes so much stress off of my wrists to be able to rest my arms perfectly and type. The lumbar support is great, it supports my back so that when I'm sitting I have better posture and less muscle cramps later.

This is a simple office desk chair with breathable mesh on the back, and 3D mesh on the seat and lumbar support. You really feel the lumbar suppot forcing you to sit straight. It's hard to explain until you actually sit in it. Like the headrest, which it went a little higher.

I sit in a chair for a bit portion of my day so having a good one is incredible important to me. After having assembled this chair, it clearly is a great one. Assembly was easy and instructions were clear, all the bolts were packaged in a very organized way which I really appreciated. The chair itself is so comfortable and I love the lumbar.

I love the price point. I know many more of us are working from. home offices, as am I. This is a far superior desk chair than the folding beach plastic webbed contraption I had been using in my office. The lumbar support literally forces you to sit up straight.
