Carbon rollators are a class of their own among walking aids. The most noticeable feature is the significantly lower weight compared to standard rollators.
"In the development of these walkers, lightness was prioritized from the very beginning. Lightweight walkers lose up to 50% of the weight of their standard counterparts."
Walkers with wheelchair function are particularly suitable for individuals who need support for shorter distances but prefer to cover longer distances while sitting.
An indoor walker is specifically designed for use indoors, e.g., in an apartment. Therefore, it is sometimes referred to as a living space walker or home walker.
All-terrain or outdoor walkers are a particularly robust type of walker. They are often equipped with soft or pneumatic tires and are especially suitable for use in rough terrain.
Shopping walkers combine a walker and shopping trolley, with bags that can carry 20 kg and have a volume of 25 l. They have a seat and provide safety while walking.
