This iconic flagship ergonomic desk chair by Herman Miller, the Aeron office chair has set a trend in the office furniture world, putting mesh back chairs in the mainstream. Still being made today, the Aeron chair is one of the best made and best selling chairs of all time.

Perfect for conference rooms, executives, desk jobs, your home office, as a gaming chair, or anything else where you need a comfortable place to sit for a long time!

Condition: Used chair refurbished to like-new condition and comes with a 12 year full-chair warranty.

Each chair is torn down to it’s frame, given a complete tune-up. Any parts that need to be fixed or replaced are fixed, and then new casters, new gas cylinder, new (made in USA) arm pads, new lumbar pad (Size B Chairs Only), new front seat foam pad (Size B Chairs Only) are installed.

Please note these are used chairs, and may come with some minor dings and scratches. We do everything we can to make them like-new, but some small scratches and scuffs (nothing significant) are to be expected.

Size A is the small size, made for children and smaller people. Size B is the regular size, made to fit most adults. Size C is the large or plus sized version of the Aeron chair.

Refurbished Herman Miller Aeron Caster Options:

Every chair gets brand new casters included – we offer several different sizes and options to choose from.

Crandall Office Furniture Office Chair Caster Options 2021

65mm Carpet casters are best for low-pile or dense carpeted floors. For medium, or longer residential carpets, we recommend 75mm Oversized Carpet Casters to help prevent the bottom of the gas cylinder from dragging on the floor.

Hard floor casters have a soft coating on them, helping them roll smoother and quieter on hard surfaces. This coating also helps protect the flooring from damage. Hard floor casters can also be used on carpeted floors.

We recommend hard floor casters for the following floors:

  • Wood / Hardwood Floors
  • Concrete / Epoxy
  • Laminate
  • Tile
  • Chair Floor Mats

Oversized (75mm) casters are larger and offer a smoother rolling experience, and also raise the chair up about ~1/2″.

Roller Blade casters offer the smoothest and quietest rolling experience of all, and work great on both carpet or hard floors. Their soft surface also helps protect floors the same as the standard twin-wheel hard floor casters.

    The chair arrived on time and in excellent condition. The refurbishment job was great (the chair could easily be mistaken for new).

  2. Jamie (verified owner)

    usGeorgia, United States

    Was a quick and easy assembly as it was mostly assembled in the box. Overall it is an amazing chair but it is a bit creeky. It isn’t enough for me to want to return it. 9/10 would recommend.

    I hadn’t heard of Crandall Office Furniture before, but after repeatedly seeing good things about them when researching online, I decided to give them a shot and order this chair.

    I have to say I’m impressed! I have literally no complaints about my experience and unreservedly recommend them to others.

    Better than New! Great customer service and exceptional experience all around.

  6. Doug Probstfeld (verified owner)

    usWashington, United States

    A few dings & one needed cleaning but nothing to get in a twist about. Otherwise, both chairs were perfect.

    The chair did not look like it had been tested thoroughly before shipping. There were some defects that should have been catches before shipping. I was not impressed with the chair.
