Review on 🪑 The Original Headrest for Herman Miller Aeron Chair H3 - Carbon | Colors & Mesh Match Classic Aeron Chair 2016 & Earlier Models - Headrest ONLY by Ursula Kennedy

First some basic information. This is an optional third-party headrest for the Aeron chair. This is NOT made by Herman Miller. Due to its design, it fits almost every Aeron chair. Various finishes are available to match the finish of your chair. Your friends and neighbors will never know it's not original and they'll all wonder how you got the Aeron HEADREST chair. Workmanship, fit and finish are good. The Engineered Now headrest attaches to your chair frame much like Herman Miller's Aeron accessories. This does not require any modifications to your chair, will not damage the chair and SHOULD NOT void your warranty. Three adjustments are planned. First, there is forward and backward adjustment by turning the lever that supports the headrest. This adjustment is securely locked in place with an Aeron-style adjustment lever. It should not slip after installation. However, to install it properly, you may need to remove the plastic caps covering the allen screws and tighten the screws. Don't overtighten or you won't be able to fully engage the release lever and it won't hold at all. Next comes the angle of the headrest. This is a regular hinge with no locking lever. He might be a little loose. If you need to tighten it, you can do so by prying off the two screw covers on either side of the hinge and tightening the screws there. The Allen key provided with the headrest will NOT fit these screws; You will need a large (like in #3) Phillips screwdriver. If you try to use a smaller screwdriver, you risk damaging both the screwdriver and the screws. You may damage the screw covers by sliding them. Includes two spare cases. I'd rather see oxide or powder coated hex head screws here and no caps at all. The third adjustment is straight up and down, and this is the headrest's weak point. This is a direct slide adjustment with no locking lever, and if it's loose enough to slide (like mine) it can't be tightened. I'm still looking for a non-destructive solution to this, but haven't found one yet. I suppose if you were sure you never want to move it again you could apply a drop of Loctite 38653 222 Purple Low Strength Thread Locker Tube, 6 milliliters each side, but that seems a bit drastic and potentially irreversible. I also tried a less drastic workaround, wrapping a few turns of duct tape around the adjustment shafts just above where I want it to sit to keep it from sliding further down. (It makes more sense if you look at the photo.) It didn't work. Engineered Now replaced my first headrest as it was faulty and the replacement was slightly better but still has the same problem - it just doesn't hold up. Engineered Now, any comments on this vertical slip issue? A locking lever for this setting would be ideal I think, but it's your product, not mine. Once installed and adjusted, the Engineering Now headrest is comfortable, supportive and looks and feels like it has always been part of the chair. However, the range of vertical adjustment is very limited, it doesn't hold vertical adjustment well, and all adjustments will likely require tightening of the screws to hold the adjustment. All in all, this is a well-made headrest that looks just like the original part on your Aeron chair and gets the job done if you don't have problems with loose adjustments. It gets a thumb from the Technical Thug for overall fit and finish, but loses a second due to the limited range of adjustments and adjustments that just don't stay in place. You might want to consider an Atlas headrest designed for the Herman Miller Aeron chair for the same price.
