“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”— 2ChanceRescue on r/BuyItForLife
“Well when I use it at home, I found that when i sit with my legs crossed (something i dont do at work), the frame digs into my thighs and is uncomfortable so Im getting a steelcase gesture instead”— TK503 on r/OfficeChairs
“But 3 weeks later and I'm not really having a great time with it. My butt hurts after just 2 hours of using it, my balls feel like they're being constricted, and in general it's just not all that comfortable.”— Odd-Local-8322 on r/BuyItForLife
“I had one at work a couple positions ago and it always hurt to sit on it. After a few months I finally stole a different chair from our conference room.”— persephone_24 on r/BuyItForLife
“I got an Aeron Size C but was too big for me. Also was getting tailbone pain. Returned and got the Mirra 2 and its been great.”— kluuu on r/BuyItForLife
“They're comfortable if you have the right body type for them. But the hype is mostly hype. There's a lot of design oversights that adversely affect the durability of these chairs. Armrests held on by a single bolt, plastic internal workings”— rabidbasher on r/BuyItForLife
“I have one but the reclining mechanism is broken as it just seems to go all the way back with no way to stop it.”— coopmaster123 on r/BuyItForLife
“I broke the lever from mine this week and they don't offer replacement parts. Next chair isn't gonna be an HM”— BelgianFriesCompote on r/BuyItForLife
“The aeron was no good for me - could never get comfy. But I went with a different Herman Miller and love it.”— jennyfromtheeblock on r/BuyItForLife
“I never found the Aeron to be very comfortable. Caused my shoulders to hurt after 5 or 6 hours.”— imakesawdust on r/BuyItForLife
“Btw, these chairs suck. My $300 gaming chair offers better support and is also sturdier.”— fokjoudoos on r/BuyItForLife
“The Herman Miller Aeron is highly-acclaimed but I personally found it uncomfortable.”— esspii on r/Accounting
Not complaints — practical notes from owners that didn't affect the score.
“Sadly, shortly after getting it I noticed lower back pain, and the Atlas headrest also feels too low for me. Now I’m really unsure if I should have gone with size C instead.”— Hamdudelda on r/hermanmiller
“The chair itself is in great shape, impressed with the refurb quality. Problem is that I'm getting a ton of pressure under my thighs on the front of the chair.”— inquisitive_investor on r/OfficeChairs
“The seat is a snug fit, i have no real room to move without rubbing the plastic edges. When leaning back I also find that the plastic edge of the seat presses into my back. Again, its not game breaking”— Dunzo123 on r/hermanmiller
