Abstract: A passenger seat mounting system adaptable for various and changing mobile technology is provided. The universal mounting system has an enclosure and a universal bracket assembly for securing to the various and changing mobile technology. The enclosure defines an enclosure cavity for said mobile technology, wherein the universal bracket assembly operatively engages the mobile technology through rear cutouts of the enclosure so that all three components are removably secured. The universal mounting system may be pivotally connected to supporting legs that are adapted to slide into standard head rest holes of a seat body. As the universal bracket assembly is adjustable, so are the varieties of mobile technology that can be universally mounted.
