This is a lightweight, adjustable, aluminum hemi walker. Easy to assemble and adjust, push in the four leg ends, and adjust with the push-button adjuster. I had it together in about 2 minutes. The easiest way is to push in the button and slightly twist the leg end just enough where you can still see the button, but it’s also now being depressed by the part of the leg with the holes. This way, you can see when you’re at the hole you need for the correct height. It opens and closes (unfolds & folds) easily, can be operated with one hand, and has a 250 lb weight limit. It’s about half the size of a regular walker and folds up with such a slim profile that it can fit and be stored behind a door. Folded up, it’s about 3” at its thickest point (less than 15” deep when opened), about 18.5” at its widest point, and about 33.5” tall for where I have it set. Your height will be determined by the height you have it set to. It has two soft and grippy foam handles (the one used to hold while walking, and a lower one to use when standing from a sitting position), and four rubberized grippy feet.
