I've been handling office furniture procurement for a mid-sized engineering firm since 2018. In that time, I've ordered roughly 220 Herman Miller chairs — maybe 235, I'd have to check the system. I've also made and documented 11 significant mistakes totaling roughly $18,000 in wasted budget. This FAQ is the list I wish someone had handed me before my first order.

Is a Herman Miller Aeron office chair worth the price?

Most people who search for an ergonomic office chair Herman Miller builds are really asking one thing: is it worth the cost? When my boss first asked me to quote 40 Aeron chairs back in 2018, I nearly choked. A chair cannot cost $1,500. That's what I thought — until I ran the numbers.

Herman Miller backs the Aeron with a 12-year warranty as of January 2025. Before we switched, we were buying $200 task chairs that developed squeaks by month five and needed replacement by year three. If an Aeron lasts a decade — and ours are still going strong — the annual cost shakes out to around $150 a year. That's less than the “cheap” chair that needs replacing every two years. It doesn't even factor in the productivity cost of sitting in a poorly designed seat for eight hours a day.

Bottom line: for anyone seated more than six hours a day, this is a no-brainer. But if you're furnishing a conference room where nobody sits longer than 30 minutes, get something less expensive. Don't spend premium money on chairs people barely use. And I should add — this assumes normal office conditions. If your team uses standing desks for most of the day, a mid-range chair might be the wiser use of budget.

Which Herman Miller chair should I choose: Aeron, Mirra, or Embody?

I get asked this constantly. I've ordered all three, and they serve different roles:

  • Aeron — the best all-rounder. Highly adjustable, breathable mesh, three sizes. This is our standard chair for full-time staff.
  • Embody — better for people with lower back issues. The backrest research is genuinely impressive. But it's pricier per unit.
  • Mirra — one step down in adjustability, but still a solid ergonomic chair. We use these for part-time staff and interns.

I went back and forth between Aeron and Embody for our design team for two weeks. On paper, the Embody's research was more compelling. But my gut said the Aeron's track record was safer — and the price difference was significant enough that Aeron was the more responsible choice for a 60-person budget. We now keep two Embodys on hand for employees with specific needs. Everyone else gets an Aeron.

This worked for us, but we're a 60-person engineering firm with predictable seating patterns. If you're running a 24/7 call center with rotating shifts, your ergonomic requirements are probably different. Your mileage may vary.

What's the most common mistake when ordering Herman Miller chairs?

Size. Hands down. No contest.

The Aeron comes in three sizes — A, B, and C — and they're not simple small/medium/large. The seat and back geometry actually change between them. I learned this the expensive way.

In January 2019, I ordered 22 size B chairs because I assumed “medium” would fit most of the team. The chairs arrived. Our tallest engineer — 6'4" — looked like he was sitting in a kid's desk. Two smaller employees felt swallowed by the seat. Nine of 22 had to be exchanged. $4,200 in redo costs, plus a three-week delay. That's when I created our sizing checklist.

The Herman Miller sizing guide is on their official website. Now I make every employee measure themselves before we order. We've caught 47 potential sizing errors with this checklist in the past 18 months — 47 problems avoided before the boxes even arrived. (I should mention: people sometimes order the wrong size because they guess their height, not their actual seat-to-floor measurement. The guide walks you through it.)

Should I buy a used Herman Miller Aeron?

The used market for Aerons is huge, and it's a mixed bag. Some used chairs are professionally refurbished. Others come from office liquidations and sat in a warehouse for years. If I remember correctly, one of our used purchases had a broken gas cylinder that cost $180 to replace.

Here's what I look for now:

  • Post-2013 models — the older mesh isn't as breathable.
  • Lumbar support included — people remove these and lose them.
  • Test the gas cylinder — a chair that sinks slowly is an expensive fix.
  • Ask about warranty — Herman Miller's 12-year warranty is designed for the original purchaser, so understand what you're getting.

A good used Aeron runs $500–$800 depending on condition. A new one starts around $1,200. The right choice depends on how long you plan to keep it. We've bought used for a satellite office. For our main office, we buy new. If you're unsure, contact Herman Miller's commercial team — they'll tell you what to watch for.

What else should I plan before ordering chairs?

Everything else.

The boring truth is that ergonomic chairs are just one piece of the office puzzle. I once ordered 30 chairs for a room where they didn't fit — my floor plan was off by 14 inches. That mistake set the entire project back.

Now, before any order, I do two things:

  1. Print a scaled floor plan on printable graph paper — free templates are all over the internet — and physically draw in every desk, chair, and walkway. Don't trust your eye.
  2. Keep a dry erase board in the storage area to map seating assignments and track which chairs are in which department.

The dry erase board sounds old-school, but it's saved me from double-ordering at least three times. And the graph paper habit caught a spacing problem that would have turned our conference room into a fire hazard.

Are Herman Miller chairs a smart purchase for schools?

This question started coming up when we furnished a local community college's administrative office. In all honesty, when people ask what are school supplies, furniture isn't the first thing that comes to mind — but if you're setting up a computer lab or an admin office, it's one of the most important budget lines.

For schools, I'd skip the Aeron and go with the Sayl or Setu instead. They're more affordable and don't scream “premium” the way an Aeron does — which matters in environments where theft is a concern. We furnished a community college computer lab with Sayl chairs about four years ago, and they've held up well.

One thing I can't speak to: K-12 classroom desks. My experience covers office and computer lab environments, not elementary classrooms. Talk to an educational furniture specialist for that.

What's your pre-order checklist for Herman Miller chairs?

Here's the list I run through before every single order:

  1. Measure your people — use the official Aeron size guide.
  2. Measure your space — graph paper floor plan with walkways.
  3. Get budget approval based on total cost of ownership, not sticker price.
  4. Decide new vs. used before comparing prices.
  5. Order one sample chair and let your team test it for a week.

That last one is the step I skipped when it cost me $4,200. A single sample chair would have exposed the sizing problem in 48 hours. If you're going to live with these chairs for a decade, one week of testing is nothing.

For larger orders, ask Herman Miller about open-box and refurbished options — as of January 2025, they list these on their official site. Verify current pricing before you commit, because rates change.
