A tilt platform for use in an HMD comprises a monolithic spring structure including a first outer planar structure, a second outer planar structure, a middle planar structure disposed between the first and second outer planar structures, a first hinge structure coupling the first outer planar structure and the middle planar structure to each other, and a second hinge structure coupling the second outer planar structure and the middle planar structure to each other. The first and second hinge structures have respective first and second hinge axes that are orthogonal to each other. The tilt platform further comprises a first adjustment mechanism configured for tilting the first outer planar structure and the middle planar structure relative to each other about the first hinge axis, and a second adjustment mechanism configured for tilting the second outer planar structure and the middle planar structure relative to each other about the second hinge axis.
