Possibly me being obtuse but aren't all jeans "pull on?" how else would you get them on?
In terms of comfiness I find boyfriend/mom jeans a lot comfier than skinny ones, other than that it will depend on the heaviness/stiffness of the denim. Pretty much all shops have some in those styles now.
I have a girlfriend pair from matalan that are really comfy and M and s stretch ones are very soft If that helps at all.
