The bed frame determines the support and stability of the bed. Hospital bed frames have varying bed decks that provide support, such as spring, grid, slat and full decks. The bed frame can also have a variety of different functions based on if they are manual, semi-electric or full-electric beds. Manual and Semi Electric beds are cheaper than Full Electric Beds and are ideal when your loved one will only need the bed for a short period of time. The functions offered in different beds can include Hi-Low functions to move the patient up and down for easy caregiver access, head/knee functions for patient comfort and trendelenburg functions for patients that require a more clinically advanced position.
