Aeron Chair Casters

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

How to Replace Aeron Chair Casters

Aeron Chair Cylinder

Aeron Chair Cylinder

aeron chair cylinderDoes 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).

How to Replace Your Aeron Chair Cylinder

Step 1: Using the chair lift lever, raise the gas lift cylinder to the highest position. Then gently lay the office chair on its side.

Step 2: Attach the shaft collar removal tools to the old cylinder.

Step 3: Thread in the removal screws to the lower shaft collar.

Step 4: As you continue to tighten the removal screws, the cylinder will slowly begin to pull away from the chair mechanism.

Step 5: Separate the chair base from the old cylinder. This can be accomplished by striking the cylinder with a wooden block and large hammer.

Step 6: Install your new chair cylinder by placing it into the chair base, then into the chair mechanism. (Note: make sure to remove the plastic cap/cover on the cylinder button before installing)

If you would like additional details, we put together a complete step-by-step instruction manual on how to remove and replace the cylinder in your office chair.
