Made by Aeron Chair Specialists

Since 2015, our Ohio shop has renewed thousands of chairs, Aerons among them, so a Herman Miller mesh replacement is everyday work for us. This premium OfficeLogix mesh comes out of that experience. It's made from durable, breathable, high-quality material and engineered for a perfect fit on Size B and Size C Classic frames, so a torn seat gets top-tier support back for long work hours at an affordable price. From a single home office to a business with a room full of Aerons, it's the ideal way to extend the life of an ergonomic investment.

We stand behind that quality with two years of cover against tearing and defects, a separate install video for each size, and free shipping within the contiguous US.

If something else on your chair is worn, you can find every spare part we carry for it in our Aeron chair parts: cylinders, back mesh, arm pads, casters, the PostureFit kit and more. Each replacement part has its symptom listed, and most have a repair video. We make parts for the Mirra and Embody too.

Before you order

Aeron Seat Mesh Replacement vs Full Seat Pan Replacement

People searching for a Herman Miller Aeron seat replacement often need less than they think. Match your chair's problem to one of these before you order:

Mesh torn, frayed or sagging but the frame is fine? Replace just the mesh

This mesh goes onto your existing Aeron Classic seat frame, which keeps the cost well below a whole new seat.

The plastic seat frame is cracked or a mounting tab has snapped

New mesh can't hold on a broken frame. You need our seat pan with new mesh, which arrives ready to bolt on.

You feel a hard edge under your thighs

That's usually the foam cushion at the front of the seat breaking down, not the mesh. A new seat foam insert brings the soft front edge back, and it's easiest to fit while the seat is apart for its new mesh. That insert fits Sizes A and B; for a Size C seat, use our Size C seat foam insert.

Got an Aeron Remastered?

This mesh is made for the Classic seat only. Use our Aeron Remastered seat mesh instead, or the Remastered seat pan with mesh if the frame is damaged too.

How to Install Herman Miller Aeron Replacement Seat Mesh

Here's the short version of a clear, guided job that needs only basic tools. The videos above walk through every step for your size: the Size C video runs about four minutes and the Size B one about five and a half.

Find your size: two dots on the back frame lip means Size B, three means Size C. Then open the matching video.
Take the seat off the chair frame, remove the screws around the outline of the seat, and lift the old mesh away.
Line the new mesh up on the frame using the center notch.
Drill the mounting holes where the video shows, then fit the mesh and screw it down. For a secure hold that won't damage the frame, our video recommends #8 x 5/8" or M4-16 screws. Stretching the mesh over the frame is the hardest part of the job, so a second pair of hands makes it much easier. Plenty of buyers also hold the mesh in the frame's groove with a few spring clamps while they work. Work your way around the seat so the tension stays even across the mesh (the Size B video shows how), and snug each screw down without overtightening, so it doesn't strip the plastic frame.
If the foam insert at the front is worn, swap it now while the seat is apart.
Put the seat back on the chair and check the tension and the tilt before you sit down for the day.

A little slack after fitting is normal. We leave some give in the mesh on purpose, because a mesh that starts out drum-tight is close to impossible to install. If yours feels loose, warm it: a heat gun on its low setting, or a household iron with a thin cloth between iron and mesh, moved slowly over the whole seat. Once it cools, the mesh firms up to a factory-tight tension and stays that way, and the seat never has to come apart again. Not every seat needs this step.

Rather not do it yourself? If you're near Columbus, drop the chair at our Lewis Center showroom and our technicians will do the stretching and fitting.

FAQ

Aeron Seat Mesh Replacement: Your Questions

How do I know if I need Size B or Size C Aeron seat mesh?

Check the lip at the top of the back frame for dots. One dot is Size A (small), two dots is Size B (medium) and three dots is Size C (large). We make this mesh in B and C, and the sizing video above points to the exact spot.

Should I replace only the Aeron seat mesh or the full seat pan?

Only the mesh, if the frame is sound. That's the cheaper repair by about $70 to $94. If the frame is cracked or a tab has snapped, the mesh has nothing solid to hold on to, so go for the full seat pan. That saving is measured against our own refurbished seat pan with new mesh; new Aeron Classic seat pans are no longer on the market, so a seat sourced elsewhere costs more again and its mesh isn't new.

Do I need tools to install the Aeron seat mesh replacement?

Yes: a drill to make the mounting holes, since the mesh comes without them, and a screwdriver for the screws around the seat. Our install video recommends #8 x 5/8" or M4-16 screws, which grip well without damaging the seat frame. One buyer's tip from the reviews: a little WD-40 helps with old screws that are stuck. A second person to help with the stretch makes a real difference too, and many buyers add a few spring clamps to keep the mesh in place.

Why does the replacement mesh not have predrilled holes?

Because the mesh installs better without them. Drilling your own holes lets the material's natural stretch set the tension on your frame, instead of fighting holes placed for an average seat. The video shows where each hole goes.

Can I install the Herman Miller replacement seat mesh myself?

Most people do their own Aeron mesh replacement, with the video for their size and a helper for the stretch. Replacing just the mesh on an Aeron chair takes patience more than special skill, and stretching the mesh over the frame is where most people find it difficult, so give yourself time for that part. Buyers who have done it report anything from 10 to 15 minutes to a couple of hours, and the stretch accounts for most of that difference. If you'd rather hand it off, our Lewis Center technicians can fit it for you.

What should I do if the Aeron seat mesh feels loose after installation?

Warm it up and let it cool. Even heat from a low heat gun, or an iron through a thin cloth, draws the slack out, and the seat stays on the chair while you do it.

Is this the same as the original Aeron pellicle?

Pellicle is Herman Miller's name for the Aeron's woven suspension, the part many owners simply call the seat fabric or bottom mesh. This is aftermarket replacement mesh, made by OfficeLogixShop to match the look, feel and tension of the original seat, with the same breathable airflow and even weight distribution. It's covered for 2 years against tearing and defects.

Will it fit my Aeron Remastered?

No. The Classic and the Remastered use different seat parts, and this mesh is for the Classic only. For a Remastered, use our Aeron Remastered seat mesh.

Is it worth replacing my seat mesh?

Almost always. A Herman Miller Aeron seat mesh replacement costs a fraction of a new seat. A torn mesh defeats the whole point of an ergonomic office chair, and replacing it restores the support and keeps the chair looking professional while the rest of the Aeron keeps going.

Is there a headrest to match my seat mesh color?

Yes. The headrest we make for the Aeron Classic is offered in all four of these mesh colors, blue and red included.
