Sand bed therapy involves immersing a patient in warm, dry sand that has been heated to a comfortable temperature. The heat of the sand promotes relaxation and aids in the alleviation of pain. The therapy is based on the principle of thermotherapy, where heat is used as a form of treatment to enhance blood circulation, reduce muscle tension, and support the body's natural healing processes. The finely granulated sand creates a gentle massage-like effect on the body, aiding in the relaxation of tight muscles and enhancing overall comfort.

Moreover, the customizable height feature plays a vital role in user comfort and health. A well-designed wheelchair should not only facilitate movement but also support the body effectively. The ability to adjust the seat height helps alleviate strain on the back, neck, and shoulders, thereby minimizing the risk of developing musculoskeletal disorders. Users can find their most comfortable position, which can also enhance their overall posture and wellbeing.
