Many of these conditions make the variable height feature of a hospital bed a medical necessity. When a patient with debilitating diseases and conditions can control the height of their bed, they can get in and out more easily and without caregiver assistance. Conditions like arthritis can require this feature to allow the patient to ease up off the mattress, enabling them to place their feet on the floor while sitting on the edge of the bed. 

Many dealers also provide customizable electric wheelchairs, allowing for adjustments in seating, controls, and additional features to match the specific requirements of users. This level of personalization can significantly affect a user's comfort and overall experience, making it a priority for reputable dealers.

Further innovation has led to the development of specialized casters tailored for specific environments and applications. For instance, heavy-duty casters are designed to support substantial weight loads in industrial settings, while non-marking casters are essential in maintaining the aesthetics of floors in retail spaces. Weatherproof casters are utilized in outdoor settings, resisting the elements while providing durability and reliability. With advancements in materials, such as polyurethane and nylon, manufacturers are creating casters that are not only functional but also aesthetically pleasing, catering to contemporary design sensibilities.
