One of the most significant innovations in manual wheelchair design is the focus on user customization. Many companies now offer a range of adjustable features allowing users to tailor their wheelchairs according to personal preferences and needs. This includes adjustable seat depth, height, and backrest angle, which can greatly enhance comfort and support. By facilitating a personalized fit, these wheelchairs can minimize the risk of pressure sores and promote better posture, contributing to the overall health and well-being of the user.

At its core, a caster is a wheeled device that can be attached to the bottom of an object, allowing it to be easily moved. The simplest form consists of a wheel mounted on a swivel bearing, which provides a 360-degree range of motion. This design enables users to maneuver heavy items with ease, reducing the risk of injury and improving productivity. Imagine an office environment where desks, chairs, and filing cabinets are equipped with casters. Employees can reconfigure their workspace quickly and without effort, fostering collaboration and creativity.
