There is a reason Herman Miller Aeron is one of the most recognized brands in ergonomic office chairs. It is comfortable, ergonomic, environmentally friendly chair for every body type. However, the Aeron chair is expensive. So to get the most out of your chair, it makes sense to upgrade/repair it with replacement Aeron chair parts. Here are the 7 commonly replaced Herman Miller Aeron chair parts list:
Office chair casters are the most replaced (or upgraded) Herman Miller Aeron chair parts. The stock aeron chair wheels will see lots of wear and tear only after a few years of use. This will cause the plastic chair casters to eventually break-down and prevent smooth rolling. If enough wear takes place you might even risk damaging your floors.
Instead of simply replacing your wheels with OEM herman miller replacement casters, it is best to consider an upgrade. The traditional "twin-wheel" casters allow your chair to move, but they have many limitations. Standard OEM Aeron casters can cause damage to hardwood floors, get tangled with hair and debris, and break after only a few years.
The Office Oasis rollerblade chair casters are regarded as the best upgrade for Herman Miller Aeron chairs. These heavy-duty wheels are encased with soft polyurethane that is guaranteed to protect your floors and will last as long as your Aeron chair does.
Here's what Herman Miller Aeron chair owners are saying about The Office Oasis rollerblade wheels:
"Outstanding new wheel set for my Herman Miller Aeron Chair. Very smooth on tile, rolls great. In the past 8 days where I use my home office often, this is much better set of wheels than the original factory ones." - Tom D.
"I upgrade my Herman Miller Aeron chair's wheels with these replacements when the original wheels cracked. Replacement needed no tools and took less than 3 minutes. The chair moves easily now and I am much less concerned about damage to my floor." - Don C.
"There are a few things you buy that you hope will be an improvement but you sort of know deep inside you'll be disappointed. These are the opposite. They are absolutely wonderful. High quality and a vast improvement over the original. I only wish I had found them before my OEM Aeron wheels destroyed the finish on my hardwood floors. At least, now I can win office chair races!" - E. Perker
Worried about the process of replacing your Aeron wheels? Don't be, it's easy and doesn't require any tools.
Office chair casters are removed by pulling the caster stem directly from the chair wheel base (You might want to use a glove or old towel for better grip). New casters are inserted by pressing the stem into the chair base sockets.
Does your Aeron chair sink to the lowest setting when you sit down? This usually means that your Aeron gas lift cylinder is worn out and no longer works properly.
Many Herman Miller chair owners may think it is time to buy a brand new chair. That is not the case. You can actually repair your Aeron chair by replacing the gas lift cylinder. This is one of the most critical Aeron chair parts to extend the life of your chair, and it will provide an additional 6 years of lift function.
Herman Miller does not provide an OEM cylinder replacement, so we designed a cylinder kit that is compatible with Herman Miller Aeron chairs. The removal of the old cylinder was one of the toughest challenges during the cylinder replacement process. So in each cylinder kit, we included our exclusive removal tool (which works by using clamps and screws to "pull" the cylinder out of the chair).
The arm pads on your Herman Miller chair can get worn out, deteriorate, peel or crack. And you can freshen up the feel and look to your Aeron chair with this simple Herman Miller replacement part.
There are two options depending on what you are looking for:
Leather arm pad replacement ($95 on the Herman Miller store). This is the classic genuine leather arm pad that is double hand stitched. They come in black, smoke, or chocolate leather colors.
Vinyl arm pad replacement ($25 on the Herman Miller store). This is the more affordable arm pad made with a vinyl material. It provides a stiff, and rigid feel for a more commercial aeron chair style. They come in black or smoke colors.
How to Replace Aeron Chair Arm Pad
The Aeron chair arm pad is easily removed with a Phillips head screwdriver. For more details on how to remove and replace Aeron chair arm pads, see the assembly instructions.
**IMPORTANT** - The following Aeron chair parts (lumbar support, posturefit support, seat & back replacement) require you to match the replacement part size to the chair size (A, B or C)
How to Check the Size of Your Aeron Chair (A, B, or C)
The best way to determine the size of your Aeron chair is to feel along the inside frame of the top portion of the chair back. You will feel small raised dots in the plastic.
1 Dot = A size (Small) 2 Dots = B size (Medium) 3 Dots = C size (Large) Lumbar
The Aeron chair lumbar support pad ($24-$95 on the Herman Miller store) is an important accessory for your Herman Miller chair. It provides two depth settings of lower back support to ensure your back is in the correct ergonomic position.
**IMPORTANT** Check the size compatibility before purchasing. There are three sizes of Herman Miller Aeron chairs: A (small chair size), B (medium chair size), and C (large size chair). See how to check the size of your Aeron chair above.
How to Replace Aeron Lumber Support Pad
The lumbar pad slides on and off the rails on the back of the Aeron chair. It does not require any tools to adjust or replace. The lumbar support pad has two (2) settings: a thick (increased support) side and a thin (standard support) side. It is best to choose the setting that feels the most comfortable and positions your back in an ergonomic position.
The top pad supports your lumbar, and the bottom pad stabilizes your sacrum. The PostureFit can be adjusted to the specific curvature of your spine.
This is a great addition to your Aeron chair, and is an upgrade from the standard lumbar support pad. The PostureFit is one of those Aeron chair parts that help users who require extra back support from the base of your spine to the middle of your back.
