Moreover, the material and design of caster wheels can greatly impact a wheelchair's performance. High-quality caster wheels are typically made from durable materials such as polyurethane, which provide excellent grip and a smooth ride over various surfaces, including carpets, tiles, and uneven terrain. Additionally, the size of the caster wheels can affect a user’s experience. Smaller wheels may be more maneuverable, but larger wheels often offer better stability and performance over obstacles. Users can choose from a variety of sizes and designs based on their specific needs, whether they are navigating indoor environments or outdoor terrains.
