Learn More About Walkers
When buying a walker it is important to think carefully about what it is for. They are all mainly designed for use out of doors (indoors it is usually better to use a "zimmer" type walking frame).
There are two broad types - the 3 wheel "Tri-Walkers" which (with the exception of the Uniscan Triumph) do not have seats and the 4 wheel "Rollators" which do have seats.
The first question to ask, therefore, is whether or not you need a machine on which you can sit. After this the important issues to address are how small and how easily does it fold for storing; how high does the seat want to be (all machines have adjustable height handles but most have fixed seat heights); will you want to be able to lift it in and out of vehicles; how robust do you need it to be.
Whatever you choose, however, there is no doubt that they all offer great freedom for most people who have difficulty in walking.
