Free269 on "Add sidebar to tablets - using my own custom twentyfourteen theme"

Hi guys,

I'm working with the twentyfourteen theme.. changing it to what I would like it to look like..

so using the mobile view, I disable the view of the sidebar by using this:

if (wp_is_mobile() == false){
	get_sidebar();

}
	get_footer();

wp_is_mobile() function just gives back a true or false answer.
How can I check if it's a tablet using PHP so I could add an other "if".

or if you know any other way to do this.. I'll be happy to listen

tnx
