By providing independent control or the side actuators 3 and the rear actuators 4, the first and second rocker switches allow for control of height and tilt, and allow for tilt forward or tilt backward.

[0031] Turning to FIGS. 5 and 6, support plates are illustrated. FIG. 5 illustrates a top support plate and FIG. 6 illustrates a bottom support plate. Upper support plate 30 provides a platform which can support a toilet seat 1 (not shown). Through-hole 34 provides an opening which may be sized similarly to the hole of a toilet seat such as toilet seat 1. Through-holes 32 provide for attachment or reception of actuators such as actuators 3 or 4, for example. Thus, side actuators may be used as front actuators in some embodiments, potentially providing for better balance and stability. Through-holes 36 are illustrated as through-holes but may be receptacles, provided for attachment of a toilet seat such as toilet seat 1.

[0032] Turning to FIGS. 7 and 8, another embodiment is illustrated. In such an embodiment, the toilet seat 1 is supported by an upper support plate 12 which is located above a lower support plate 14.
