If it has the button I'm not sure it is compatible with mine; at the very least I would have to take off the seat fabric and detach the whole armrest from the inside. Question is whether my seat would support the mounting hardware for the one with the button.

The way mine was designed, there would be no need to do anything but unzip the zipper, pull off the cover, pull on the new and zip it up.

If you could keep me posted, I would definitely pay $25 for the zipper-cover style, and would also buy it if I could be sure the button style one would mount to my seat.

Thanks for helping with this!
