This was my first order with wayfair, which went very smooth. The original shipping expectation was about 10 days, which was shortened via an email notice, then extended back to the original one. 
The chair's seat cushion is comfortable, as is the back. It's shaped well in that regard. I'm 6' 210 lbs and the height of the armrests render them basically worthless while typing. If I rest my hands in my lap, that's the only time my elbows touch the armrests. In a locked position the chair wobbles quite a bit in all directions. I've sat in the chair for about 3 hours total and it already has a pronounced lean. 
All in all, the chair is worth the ~$70 for it, but don't expect anything special or sturdy. It's truly your run of the mill office chair that will likely have a short life span.
