I purchased an Aeron chair by Herman Miller. The recommended size was a B/C but Herman Miller recommends that anyone falling in the B/C range order the B size. I am 220lbs, 6'2" and was in the upper limit of the B/C range. The B size was way too small, The lumbar support needed to be set so high on the supporting rails that it popped off and the seat was almost 6 inches from the back of my knees. Use the sizing chart with caution or, better yet, call Madison Seating and speak with a sales rep before you buy. If you have to return the chair the shipping cost, which are on you, can be very high, the shipping from California was about $165. Madison Seating was good enough to waive the restock fee of $50. It was an expensive lesson, but the chair was delivered within the stated timeframe, there is a 30 day money back guarantee and Madison Seating was responsive.
Thanks for the feedback! We are happy you are satisfied with our services. The Herman Miller size chart is pretty general. Based on our 10+ years of experience selling the Herman Miller Aeron chair, we would definitely recommend the Size C for anyone over 215lbs.
