Surprisingly easy to remove the leg portion. This is very useful for decreasing the weight of the chair if you need to move it.

You might be able to get to the side securing fasteners with out removing the leg portion, but it is easy to do.

Carefully lift up on the main seat cushion. It is just velcro (ed) in place

then pull the top of the leg cushion portion forward

Next release the thin crossed velcro straps by pulling them forward as well

Use 5 mm hex to remove the two bolts to the left or the two circles in the drawing

then lift up on the securing points latches

then you can lift up slightly on the leg portion to move it away from the chair

carefully as it is still attached electrically

the leg portion does had wheels on it so it moves easily after you lift it free (it is quite heavy)

just a close up of how the leg portion connects and what it rotates on

with a small flat head screw driver or similar, gently push the center of the connector toward the outside of the chair as you pull the entire connector forward.

There are two you need to disconnect to the right o the red squares.

2nd photo shows them disconnected

there are three #2 Phillips screws to be removed along the back of the panel shown in yellow numbers on the first photo

there are four #2 Phillips screws to be removed along the front and top of the panel shown in red numbers on the first photo

The second photos shows how the top center screw can be Gard to get to

all of these screws are accessed from the inside of the arm rest. Near where the outsides of where your thighs would be if you were sitting in the chair

here I checked all the screws tight. the larger ones are #3 Phillips while the smaller ones are #2

The 2nd photo shows the screw I found loose that was making my arm rest move too much

I think the entire side panel is attached by the three circles shown in the photo

to the right of the two red circles and to the upper left of the green circle are the three points

probably have to disassemble the grey plastic below the arm rest to get to the green bolt

just a photo of the bottom if your curious

chair is very heavy lift carefully

I'll add more to this guide when I take it apart more (currently together and running well:)
