Depending on your model of chair, that mounting position might not work. I have the Berkline 13175's and tried for hours to position the shakers as shown in that image. However, the power reclining mechanism would always grind on the shakers...the recline still worked, but I didn't think the metal-on-metal was good over the long-term.
I then positioned the shakers behind the seats as shown on the previous page of this thread in my post...but the shaking seemed localized. However, the third time I finally struck gold.
I flipped over the chair and decided to mount the shakers to the wooden frame that supports the seats. I attached mounting brackets to a 1x6 board and screwed the brackets directly into the wooden seat frame.
This provided a wide base tied securely into the seat frame to mount the shakers. The more you "tie" the pro-shakers into the seat frame it improves the impact....and by spreading the effect across the entire seat frame it smooths out the shaking and cuts down on a feeling of localized shaking.
I've been running with this set-up in my back row of seats and I am very happy with the results. I still need to remount the front row and can post pictures if needed.
