In addition to preventing pressure ulcers, many special beds are designed with adjustable heights and backrests, allowing for easier access for both patients and caregivers. For patients with limited mobility, these adjustable features enable them to find a comfortable position that meets their individual needs. Caregivers benefit as well; the ability to raise or lower the bed can reduce strain on their backs, making it easier to provide necessary care without risking injury. This ergonomic consideration is vital in a nursing setting where the physical demands on staff can be significant.
