Seamless ordering- excellent customer service- quick delivery (arrived within 6 days directly to my office). The YouTube instructions were a handy cross reference to the written instructions - the desk and the chair took about an hour to assemble. I am incredibly happy with both the aesthetic look of the desk (and lots of compliments!) as well as the mechanical features- quiet and easy to use. I ordered the wood version as a treat to myself and happy that I did! Also ordered the matching cabinet that came pre-assembled! The discount increased to 20% off on the day I ordered - and the company happily refunded me the difference.

Comfortable chair! Love it!

Love my new GrinChair by Effydesk. Comfortable and conforming with multiple adjustments for height, arm rests, back and lumbar with added the plus of a clean modern profile. No more need for my bulky Obus form!

had it for three months and i really like it. Sleek, looks great and supports my back well. I still alternate between sitting and standing and have noticed less and less backpain!
