A three- or four-wheeled mobility walker/rollator including a foldable or collapsible frame assembly including a main or anterior frame assembly and a posterior frame assembly, three or four wheels coupled to the bottom or base of the frame assembly, and at least two crossbar handles coupled to the top of the frame assembly. The crossbar handles are placed one in front of the other with the first posterior crossbar handle being aligned with or slightly behind the middle of the back wheel posterior to the bottom of the walker frame. The crossbars can be of a sufficient width and curvature to provide a continuous support for the forearms when the user is standing, and can provide more frontal plane stability and balance during locomotion compared to the handles of a traditional walker.
