I took a look at the website where the walker is described. My mom, who passed away a year ago, had one like that. It was great for walking up and down the hallways at her assisted living facility and gave her greater control over the balance issues she was having. However, it was so heavy that I could not lift it in and out of the car when I had to take her places. The few times I tried it I was exhausted, so we just used the lightweight aluminum walker that would fold up easily.
It is really nice, though, to have the seat and the seat lifts up so that you can easily store your wallet, cell phone, etc. If you go shopping you can use it to sit down when you tire and take a rest rather than looking for a chair or bench, etc. There are lots of advantages to it but you need to consider the weight if you are going to take it outside of your home.
