Abstract: A reversible spring assembly is coupled to a bed frame and capable of being inverted from a first position to a second position without detaching the assembly from the bed frame. In one embodiment, the spring assembly includes top and bottom springs arranged in rows within a frame with one or more rigid support bars disposed between the rows of springs. If the user wishes to adjust the position of the assembly in the bed frame (e.g., to create a loft-style configuration), the user need only invert the bed such that the assembly previously positioned at in a right-side-up position at the bottom of the frame is positioned in an inverted position at the top of the frame.
