What Herman Miller Aeron Size B owners say

“Reclining to meditate in this chair is amazing!”
— @kylelangley8818 on YouTube
“The Aeron Remastered and the Classic are both really amazing. Cannot beat the recline and the adjustability of just about every aspect of what’s important for tasking or relaxing.”
— @MichaelCConti on YouTube
“I wanted to love my HM Aeron (supplied by work), but in the end my $150 Covid Office Depot chair is way more comfortable. Chairs are such a personal item and brand/cost don’t guarantee comfort”

— @patrickcadette on YouTube
“I recently bought a Doro S100 and it's very comfortable. Now, I wouldn't recommend it if you are above 6.”

“I recently purchased a Sihoo S100 chair and after 2 days of use there was staples popping out of the side of the seat. This caused one side of the seat to essentially deflate.”
