A hospital bed (10) has a base (28), an upper frame (30) above the base (28), and a lift system (32) to raise and lower the upper frame (30) relative to the base (28) between a low position and a high position. The bed (10) also has control circuitry (82) coupled to the lift system (32) to command operation of the lift system (32). The control circuitry (82) further includes an angle sensor (86) to provide a signal indicative of an angle at which at least one of the base (28) and the upper frame (30) are tilted away from a substantially horizontal orientation. The control circuitry (82) has an indicator (92) that is activated to indicate to a caregiver that the lift system (32) should be operated to move the upper frame (30) to the low position when the angle sensor (86) indicates that the angle is greater than a threshold amount.
