Durability and ease of use are also essential factors in the design of these devices. Smart rollators are often made from lightweight yet sturdy materials, making them easy to maneuver both indoors and outdoors. They are designed to fold easily for storage and transportation, catering to the needs of active individuals who may wish to take their rollator on outings or trips.

Safety features are also essential. Potty chairs should come equipped with sturdy armrests, non-slip bases, and, ideally, locking mechanisms to prevent accidental movement during use. Additionally, the materials used should be easy to clean and maintain, as hygiene is a critical concern. Many products are made of high-quality plastic or metal, combined with seat covers that can be easily wiped down or removed for cleaning.
