A height and angle adjustable bed having a rolling base which utilizes a unique pivoting base having castors and a unique support arm assist spring mechanism. The pivoting castor base allows movement of the bed in any direction on the plane of the floor when also positioned at any user desired height while also providing a stable and lockable support for the bed. The support arm spring mechanism provides an initial assist force when the bed is in a nearly or fully lowered position and thereby minimizes the force required by the linear actuators used to raise the bed.
