Search no more... your chair awaits you =) If like me you are looking for a chair that is both comfortable and sits high if desired (for a standing desk) then you got it made with this unit. Not only does the chair offer fine qualities the vendor Offices- Warehouse truly strives to offer excellent customer service every step of the way. As a business man I expect reliability, speed, and quality from a vendor and this vendor hit every mark. My questions and delivery time was answered with lightening speed and care.Pros:- Chair can extend higher than most chairs (can reach about 35 inches for chair seat height)- Back of chair is mesh so your back won't sweat- Arm supports sit higher than average so they are useful and do the job- Chair cushion is robust making the chair comfortable and won't get hot like some other chairs- Wheels are of decent quality so they won't scratch wood floors- Back support actually has a tilt function so you can increase or decrease the back support tension (basically you can lean back)- Because the chair seat is larger than most, you don't feel like the chair is going to dump you out of itWhat could be improved:- Every high sitting chair that I have come across sinks a little bit when you have it extended all the way and go to sit in it. This chair does allow a higher extension than most but sinks a little when fully extended. To get around this issue I recommend buying a piece of 3/4 inch foam split pipe insulator (about 3 inches in length), putting the chair to desired height, place the insulator around the pipe where it starts to enter into the other pipe, and then put 2 metal hose clamps right on top of each other tightly around the pipe insulator. And voila you lock the chair height in place and can still rotate as desired.
