I was going to buy a chair from Madison Seating. Then I heard some bad news about their processes and products. They seem too shady.
I was referred to Crandall Office Furniture instead. My Leap V2 will be an extra $100+ ($450 after tax) from here but I think it's worth it. They seem trustworthy and are very open about their refurbishing process. Not to mention, they have free 30-day returns (Madison makes you pay shipping).
They currently have a promo for 10% off office chairs. Promotion expires May 15th.
(Please share any experiences with Crandall)
