The Nimbo Posterior Walker gives adults or children stability and support for better ambulation. The adult or pediatric posterior walker is lightweight, height-adjustable, and folds for transport. Its 5-inch front and rear wheels are soft rubber wheels that can grip any surface and will not slide backward. Rear wheels can be set to forward rolling only for those with limited ambulation ability. A smooth textured handgrip increases comfort while using the walker. Available in a variety of colors and sizes, this size medium model supports up to 150 pounds and features a fun and shiny Knight Blue frame.
