## Abstract

A seating apparatus having a base, front and rear upright support members, and two vertical transverse support members. The transverse members comprise the seating means. Extending from the rear upright support members are two vertical supports holding two rear upright support members. Leg support members are rotatably mounted to the transverse support members. Coupled by ratchet devices to the rear of the seating means is a seat back. The seat back is composed of two vertical seat back members separated by horizontal seat back members. The ratchet allows the seat back to be 90 degrees from the seating means or to rearwardly pivot to parallel with said seating means. Legs formed at the top back of the seat back support the seat back against the ground when the seat back is fully reclined. Arm support members are pivotally coupled to the sides of seat back. Also disclosed are two pneumatic devices. The first pneumatically advances a horizontal armature. The second pneumatically advances a vertical armature.

## Claims

### Claim 1

A pneumatic device comprising:
a base;
vertical pipe means rising from said base;
sleeve means disposed about said vertical pipe means and coupled to perpendicular sleeve means, said sleeve means being able to travel up and down along said vertical pipe means;
horizontal pipe means mounted in said perpendicular sleeve means, said horizontal pipe means being able to travel frontward and backward along said perpendicular sleeve means, and said horizontal pipe means housing an inner pipe;
said inner pipe having a seal at a first end, and a second end;
pressure bulb means coupled to hose means in air communication with said horizontal pipe means so that a squeeze of said bulb pushes air against said seal and moves said inner pipe within said horizontal pipe means.

### Claim 2 (depends on 1)

The pneumatic device of claim 1 further comprising connecting means at the second end of said inner pipe.

### Claim 3 (depends on 1)

The pneumatic device of claim 1 further comprising a metallic ball at the end of the vertical pipe means.

### Claim 4 (depends on 3)

The pneumatic device of claim 3 further comprising wires to connect said ball to electricity.

### Claim 5 (depends on 1)

The pneumatic device of claim 1 further comprising wires to connect to an electrode insertion device mounted on said connecting means.
