It is difficult to purchase a desk chair over the internet ... However this is the second chair we've purchased from Wayfair and both are exceptional. This chair is for an higher-end office desk environment and if it just went on looks, this would be a 10. Then you have all those other things to worry about like packaging, shipping, comfort, use, and overall quality of the chair itself. 

Well shipping, it was freaky fast again, well done Wayfair. 
Packaging, Well packaged not a piece of foam to deal with.
Assembly, Simple did it in 5 minutes. 
The build quality, this chair is very well made ... heavy and solid. User is 6' 210 lbs and very happy with his chair.
Comfort, a 10 ... very dense memory foam feeling seat and back. Cool and comfortable. 
Use, easy to use controls.

Very happy, again ...
