Vertical supports attached to the seat portion include multiple lift angle holes that allow the seat to be elevated to different lifted angles. Elongate members pivotally connect to vertical supports. The elongate members attach via one of the multiple lift angle holes. The elongate members are able to attach to different lift angle holes. The lifted angle is determined by the first one of the at least two seat position holes. A lift generator is attached to the base and extends to lift the horizontal seat portion into the lifted position. The lift generator contracts to return the horizontal seat portion to the seated position. ## Claims ### Claim 1 A device for seat elevation, the device comprising: a base; a seat portion, wherein in a seated position the seat portion is at a first angle, wherein in a lifted position the seat portion is at a lifted angle, and wherein the lifted angle is formed by the seat portion and a plane parallel to the base; a first vertical support attached to the base; a second vertical support attached to the base; a third vertical support attached to the horizontal seat portion, wherein third vertical supports comprises at least two seat position holes, and wherein each of the at least two seat position holes has a corresponding lifted angle; a fourth vertical support attached to the horizontal seat portion opposite of the third vertical support, wherein the fourth vertical supports comprises at least two seat position holes corresponding to the at least two seat position holes of the third vertical support, a cavity is formed within the base and the vertical supports; a first elongate member pivotally connected to the first vertical support and the third vertical support, wherein the first elongate member is attached to the third vertical support via a first one of the at least two seat position holes of the third vertical support, wherein the first elongate member is configurable to attach to a second one of the at least two seat position holes of the third vertical support, and wherein the lifted angle is determined by the first one of the at least two seat position holes; a second elongate member pivotally connected to the second vertical support and the fourth vertical support, wherein the second elongate member is attached to the fourth vertical support via a first one of the at least two seat position holes of the fourth vertical support corresponding to the first one of the at least two seat position holes of the third vertical support, wherein the second elongate member is configurable to attach to a second one of the at least two seat position holes of the fourth vertical support; a lift generator attached to the base, wherein the lift generator extends to lift the horizontal seat portion into the lifted position, wherein the lift generator contracts to return the horizontal seat portion to the seated position. ### Claim 2 (depends on 1) The device of claim 1, wherein the first angle is between the seat portion and a plane parallel to the base, and wherein the first angle is zero degrees. ### Claim 3 (depends on 1) The device of claim 1, wherein the lifted angle is between 0 degrees and 8 degrees. ### Claim 4 (depends on 3) The device of claim 3, wherein the lifted angle is 3 degrees. ### Claim 5 (depends on 1) The device of claim 1, wherein the second vertical support comprises three seat position holes. ### Claim 6 (depends on 5) The device of claim 5, wherein a middle seat position hole corresponds with the lifted angle between 10 degrees and 18 degrees. ### Claim 7 (depends on 6) The device of claim 6, wherein the lifted angle corresponding to the middle seat position hole is 14 degrees. ### Claim 8 (depends on 5) The device of claim 5, wherein a lower seat position hole corresponds with the lifted angle between 19 degrees and 25 degrees. ### Claim 9 (depends on 8) The device of claim 8, wherein the lifted angle corresponding to the lower seat position hole is 20 degrees. ### Claim 10 (depends on 1) The device of claim 1, further comprising a second lift generator attached to the base. ### Claim 11 (depends on 1) The device of claim 1, further comprising a controller configured to operate the lift generator between the seated position and the lifted position. ### Claim 12 (depends on 11) The device of claim 11, wherein the controller is attached to the base. ### Claim 13 (depends on 1) The device of claim 1, further comprising: at least four wheels each attached to the base; and at least two-wheel locks configured to prevent at least two of the at least four wheels from moving when in a locked position. ### Claim 14 (depends on 1) The device of claim 1, wherein the base comprises: two long support members, wherein the lift generator is connected to one of the two long support members, and wherein each of the two first vertical supports are attached to one of the two long support members; and one horizontal support member, wherein the one horizontal support member connects to each of the two long support members. ### Claim 15 (depends on 1) The device of claim 1, further comprising: a hose configured to attach to a toilet water supply; and a water sprayer connected to the hose and connected to seat portion. ### Claim 16 (depends on 1) The device of claim 1, further comprising: a water tank; a hose configured to attach to the water tank; and a water sprayer configured to connect to the hose. ### Claim 17 (depends on 1) The device of claim 1, further comprising a water heater. ### Claim 18 (depends on 17) The device of claim 17, wherein the water heater is configured to heat water stored in the water tank. ### Claim 19 (depends on 17) The device of claim 17, wherein the water heater is configured to heat water within the hose.
