Engineered Now Headrest For Classic Herman Miller Aeron Chair H4 for Remastered Graphite

Perfect accessory. Very high quality and feels like Herman Miller made it themselves. Color and material fits perfect with aeron chair. At least for space grey version

If this was a lot cheaper I'd give it 5/5, but given how expensive it is I really cannot justify that rating. It's reasonably comfortable but not super comfortable. The adjustability of it also isn't fantastic and it can shift too easily.

This review is for H4 graphite headrest for remastered HM chair. After reading many negative reviews about this item I was worried about headset moving all over the place as many described tightening up issues. Well, those who left these reviews either got a different product from the one I’ve received or must have screwed up something when assembling/adjusting this headrest to a chair. All parts of this headrest where tight enough out of the box for me. I’ve only tightened up the height position slightly to make it even more firm. If you would like to tighten up even further then you could and this would keep the headrest in one position without possibility to move it. Some reviews said that plastic caps covering the screws where hard to remove. Honestly with a bit of care and patience they were peace of cake to remove, without damaging. If however somehow you’ve managed to damage these, then guess what, product comes with a spare pair of these caps to replace. Some other reviews mentioned that horizontal adjustment (silver bars adjustment) are not tight enough. That is not true in my experience but if you still have a problem with tightness than this product comes with clamps which you can assemble on these silver bars to lock the headrest in desired position. Product quality is great. Mesh matches exactly the colour of the chair. Mash structure is slightly different but you really need to look closely to notice this. The only downside is that mesh is touching neck skin directly and while it is overall very comfortable, it might feel a bit cold, especially in a winter time. I think nice plushy pillow would do much better here but then it would not match the chair as good as the mesh. The only cons is the price. It’s a lot of money for a peace of plastic and mesh. Summarising, I am very happy with the product but unhappy with negative reviews as they were very misleading for me to an extent that I’ve almost purchased atlas version of this headrest from USA (delivery to UK would take much longer). I am glad I’ve choosen this one over atlas.

Been using it for a couple of years with my HM Aeron. A must have for Aeron users, very comfortable! Highly recommended!

This is the H4 In Graphite for the "Remastered" Herman Miller Aeron chair. This quality and finish makes it look as if it's a genuine Aeron accessory. Take the time and READ the instruction manual to INSTALL and adjust the headrest AFTER you've adjust the chair to your comfort. (The directions for the chair are on Herman Miller's website.) After adjusting it for my comfort, I tightened the all of the headrest's hardware a 1/4 turn clockwise to hold the settings a little better. EN doesn't recommend this, as they say the factory settings allow for easy adjustments. I agree, but I wanted it tighter than it was. I never thought an Aeron could be improved, but this headrest does it- DEFINITELY worth the $180.00! THE MODIFICATION: I had the same problem that many people had, in that the headrest would not stay adjusted for height, and there's no way to tighten it to keep the headrest from falling. I decided to use 1/4" ID fuel line to solve this. 1 foot of this product cost $2.00 at my local hardware store. This hose is reinforced inside to maintain its shape, which makes it very strong. To lock the headrest in at maximum height, I needed two pieces that were 2 3/8" long. (I cut them from the part of the hose that has no writing.) I then a piece in a vice just tight enough to hold it still while I carefully cut through ONE side of it lengthwise. Use a new blade in a utility knife and SLOWLY make 3 straight cuts, each a little deeper than the last, following the previous cut. You will end up with a sleeve that fits perfectly over the rod. Open the slit wide enough to go around the rod and slip it on. The hose will close up perfectly around the rod. You won't even see the slit. They are very stiff and don't look too obvious. Mine are on a Graphite (Gray) Aeron. If you have a Carbon (Black) chair, they'll blend in even better! Adjust the headrest where you'd like it, measure how much tubing you need ABOVE the bracket, and follow the directions above. See pictures...
