massage option

[my16tahoe]

I have a 2016 LTZ Tahoe with the heat and cool function in leather. My issue is a I really need a massager option for the front seats due to the long distance drives I do.

Has anyone had any experience with a add on feature that can be slipped under the leather or the option of swapping out newer seats from a Tahoe/Denali/Escalade?

Thanks
