One of the standout features of 4WD electric wheelchairs is their superior traction and stability. The advanced design allows for better weight distribution and balance, reducing the risk of tipping over on inclines or during rough rides. Many models also come equipped with all-terrain tires that enhance grip, further broadening the user's mobility.

One of the primary functions of hospital beds is to ensure patient comfort and safety. Modern hospital beds are designed with advanced features that promote optimal patient positioning. Adjustable beds allow healthcare providers to elevate or lower the head and foot sections, making it easier for patients to sit up or lie down comfortably. This adjustability is particularly beneficial for patients recovering from surgery, as it helps reduce muscle strain and facilitates better circulation. Furthermore, the incorporation of side rails and locking mechanisms enhances safety, preventing patients from accidentally falling out of bed, especially those who may be disoriented or at risk of mobility issues.

A semi-electric hospital bed (E0260, E0261, E0294, E0295, and E0329) is covered if the patient meets one of the criteria for a fixed height bed and requires frequent changes in body position and/or has an immediate need for a change in body position.
