- More adjustable arm rests (they go back and forward too)
- New mesh material which is apparently more supportive
- New back support mechanism which is a combination of the two previous options (which you could not put together) - both the lumbar and the pelvis supports
- Chair is angled 1.8 degrees further forward
- Tilt mechanism causes the chair to hug your body more, with less latency
- A new white-ish color option
Other than that it looks the same.
I'm in the middle of an assessment of both Aeron and Mirra 2, so yeah I've been in the details a bit too much this week...
...as a programmer I find it easy to make decisions based on facts, but when it's a decision based on how something feels, I lock up in panicked indecision and almost always make a choice I regret!
I have an Aeron and a Mirra 2. The Mirra is both better looking, better constructed and more ergonomic. There are more adjustments, and the mechanisms are very intuitive and integrated into the design. Perhaps the new Aeron will bring it up to par.
I have both as well and the Mirra 2, in my mind, is the way to go. For me, the Aeron has the edge of the seat part where the back of my thighs rest and it starts getting uncomfortable after 15 mins. The Mirra doesn't have this issue. The Mirra back also hugs my shoulder blades a little better. The plastic back of my Mirra doesn't bother me vs. the Aeron mesh.
I would recommend the Mirra for anyone looking at Aeron. They're usually cheaper too. I got my Mirra on Amazon for around $600 which the Aeron was going for, I think at the time, around $900.
I always get Aerons used on CL. In the Bay Area, if you shop around for a few days, you can get one for $300. My last one came from a dentist office. I sold my OK-condition size C for $280 and picked up a better-condition size B (which is actually my size, at 6'0 and 220# with a 44" chest and 36" waist) for $300 later that day. It was the second one I called about; the first person didn't call me back fast enough.
Agree that the lumbar support is more comfortable but PF does have some benefits. I like that they redesigned the arms which support the seat above the part which connects to the top of the gas cylinder. Hopefully this will have less tendency over time to wobble.
yeah I went and read... looks like it's just "upgraded" components. Never know if that means cheaper for us or actually better. looks like it's rev 2 of the ergonomic adjusters. There were a few things like the tilt adjust that did wear out when you toss your full weight back against one ratchet
mechanism, it's going to get messed up.
As for feel stuff I just try before I buy. Buy them on craigslist at market price, try them for several months, sell the one you don't like. Simple. Or try, sell, try sell, buy new.
I recently got an aeron, and struggled with which of the 2 back support options to get. I ended up getting both (an extra $100-ish). I find myself using the lumbar version more. While you can't use both options at once, I've enjoyed using the lumbar option more, and it is easy to swap them out. It's great that they are combining the two options.
