Below are some commonly asked FAQ before you think you are in a bad situation.
Q: How should i clean the Aeron chair?
You may clean with room temperature water using a fibre cloth.
Never apply harsh detergent, hot steam nor UV light
Incorrect cleaning agents may permanently damage the structural integrity of the mesh, causing tears.
Q: The tension for locking the armrest on my Aeron don’t feel the same.
It’s not uncommon for the arm tension to feel slightly different from side to side, with one arm feeling a bit stiffer. Both arms share the same basic up–down mechanism, but the internal parts on each side are not identical.
Using different materials on each side or setting to a certain tension is a deliberate engineering choice to balance smooth adjustment with solid locking, not a defect or cost-cutting. This layout is built into the arms from the factory and cannot be modified or changed.
On a new chair, it is normal for the mechanism to feel tighter at first. As the parts bed in with use, the movement typically becomes smoother and a little lighter, so that initial stiffness is expected.
It will not affect the usage of the chair, as most people set their arm height once according to their arm length and rarely move it up and down every day. It only becomes a problem if the arms are no longer able to lock and hold their position – that would be a fault. A slight difference in feel between left and right is considered normal.
As a simple guide, adjust the armrests so that:
– Your shoulders are relaxed, not hunched up.
– Your elbows are roughly at 90° when your arms rest on the pads.
– Your forearms are parallel to the desk surface, with your wrists straight when typing or using the mouse.
Once this is set to your arm length and desk height, there is usually no need to keep adjusting the arm height.
Q: My Aeron Chair feels wobbly.
Q: It must be wobbling because the joints underneath the chair is loose and the nuts are not fastened.
This part is meant to be loose and it does not secure the chair.
For the remastered Aeron, it has a similar design and if you look from the back of the seat, you will notice that the seat is hanging loosely on the bolts.
Q: My Aeron has a waxy feel or has a little plastic smell.
If you are not used to the feel of mesh, you can consider getting the Breathshield Aeron Chair Fabric Cover.
Q: My hard casters are shredding.
Q: How to change the casters?
Q: My chair is not tilting properly.
Q: Why is there some noise when I tilt, sit or move the chair?
This is one of the most common questions we received over the years and it’s no wonder because many users assume that the chair should be totally silent for forever.
Having a little sound is natural and inevitable from the metal to metal contact or as the plastic frame flex. Some parts of the chair could really create noise easily, like the seat or pivot links, the plastic covers for the gearbox, etc. Lubricant can only reduce some friction and noise from contact abrasion, not totally. If it’s a rather new chair, the lubrication may be setting in, and noise will usually get lesser as the lubrication spread. If it’s an old chair, get some silicone grease(Not WD40 or similar!) and apply at the joints. The old application could be wearing off or gunked up with plenty of dust. Different model, age or version of the chair may have a different condition, it’s hard to pinpoint one common part or expect all to sound the same. Of course, it also depends on other matters like the user’s weight. Also, the chair being used in a quiet and enclosed room may make the sound more noticeable than in an open area.
Some parts of the chair are designed to be loose, so the chair can have its full finesse for its ergonomic features. These loose parts may inevitably create some noise as they knock or rub against the contacts. Since those are part of the design, nothing could be done. The wheels can also produce unnecessary noise. This can come from the stem that connects the casters to the chair, the internal rotary component or the surface of the wheels. For the stem, the new design from the German hard floor casters should reduce noise by a lot with its modified design, but not totally. If dirt or dust gets caught in the wheel, then friction is likely to increase along with noise. Last is for hard floor casters, it has a polyethene coating that promotes adhesion to the floor. In some cases, it can get too tacky with certain flooring and creates some noise. Or it can happen when strong cleaning agent gets in contact and somehow deteriorate the surface’s condition.
There’s really nothing a technician can do to make it absolutely or forever silent. Noise normally comes from parts that move. It’s hard to be totally silent with so many moving parts to get its ergonomic features and that’s probably the reason why noise is not covered in the warranty. Despite that, in almost all cases we have seen over a decade, we have not seen any functional failure, we suggest users not to overthink of the little noise that may appear.
Q: Why is there a squeaking sound at the wheel area?.
It could be dirt or dust stuck inside the wheels creating friction, or it could be the surface is too tacky for your flooring. Strong cleaning agent may create a chemical response to the surface of hard casters and starts creating noise while rolling. Full carpet casters create noise especially on hard floor because the nylon casters don’t have any cushioning.
You can try placing a rug under the chair, and see if the sound goes away. If it is due to too much friction between the wheels and your floor, there’s nothing that can be modified except placing a rug underneath.
Q: Why am I feeling weird and not comfortable?
If you are already in a bad posture for a long time, your muscles and bones may need some time to adjust. Nothing to do with the chair, more to do with your back.
Q: The tension on my Posturefit SL don’t seem to work much. (Remastered Aeron)
The posturefit SL on the remastered Aeron only allows slight adjustment.
It now serves to complement the zonal mesh support.
It doesn’t give a very protruding feel like pushing the pelvis forward like in the older designs of Aerons.
Q: My Embody’s Backfit adjustment can’t turn, it’s stuck.
First tilt your chair back into the upright position.
Turn the handle anti-clockwise with force.
Q: My Embody’s height adjustment isn’t working?
Small issue, easy fix.

Q: Why are there scratch or crease marks on my new piece of leather furniture?
Just like wrinkles on our skin, those are natural markings that can’t be avoided.
Q: Why is one side of the PosturePilot headrest on the up-down adjustment feeling looser?
The interior of the specified component contains two rings, each positioned within a groove on the stem.
One side is deliberately designed to be slightly looser than the other to avoid excessive tightness and to allow movement. If both sides were tightly snug, it could cause excessive resistance, strip the nylon chassis or cause the headrest to be stuck. More importantly, this improved design ensures the headrest can be adjusted freely without obstruction.
To meet ergonomic standards, the up-down mechanism is engineered to operate smoothly, enabling continuous adjustments as the user tilts the chair.
Q: My Engineered Now or Posturepilot headrest up-down slider mechanism doesn’t lock in place or feels too loose. Is there something wrong with it?
No, this is by design for ergonomic reasons. The up-down height adjustment is not meant to lock the headrest firmly in place.
Ergonomically, your body should move throughout the day to maintain proper blood circulation and avoid staying in a fixed position.
The headrest is designed to move freely with you as you tilt and adjust, and all adjustments can be made easily from a seated position.
In fact, when the headrest was originally designed by Israeli engineers and researchers, it didn’t even have stepped adjustments—it was designed to be even more fluid and responsive to movement.
The headrest should also be supporting from the back of your neck, not pushing your head forward.
You don’t have to. It’s recorded from the date of purchase and we will always keep the record.
It depends on the specific import batch.
Because we source commercial bulk inventory (stock originally intended for large corporate contracts), the documentation often differs from standard retail sets for two reasons:
- Eco-Friendly Bulk Shipping: Commercial units are often shipped without individual pamphlets to reduce waste.
- Supply Chain Protection: As a parallel importer offering prices ~40% below retail, we must protect the identity of our overseas suppliers. This sometimes requires removing retail inserts or traceable documentation.
However, we ensure you have the best instructions available via the official digital guides:
Authenticity Guarantee: Even without the paper booklet, your chair is 100% Brand New and Original. You can verify this by checking the Herman Miller logo embossed directly into the back frame and the patented 8Z Pellicle™ mesh, which are impossible to replicate on fakes.
