Manual WeaverSeat, an experiment for more comfort while weaving

This is the first series of pictures of how the parts of the WeaverSeat are mounted together. Expect a new series to replace this one soon.
Also a manual will soon be made that describes all the steps to make each single component.

The assumpion is that sitting more erect is less tiresome and is less demanding on one's knee and hip joints and one's spine. But there is more to weaving than just sitting. The women who is weaving has to apply the right tension on her work. Will less strain while sitting and proper control over the work go together?

Less bending of the thigh versus hip bones and spine
The women, who is weaving controls with the movement of het body the tension on the strap behind her back. It must be easy to do so with the pressure her knees on the knee support or with her feet. Or by a mix of these two ways.
Try out different positions of the knee supports: higher and lower, closer by and further off.
You are free to shift your feet
The knee rest turns with your leg to and fro. Moving your legs helps the circulation of you blood and reduces stress.
Try again to slightly change the height of the knee support for best comfort.
The 14 parts to be put together
- T-frame (2 beams attached in T-shape)
- 4 bags around a wooden support & cushions)
- stick for attaching seats
- 4 wedges
- 1 stabilizer stick, bent or with end rubbers
- 1 knee support frame with sheet metal end
- 1 stick for knee rests with notch in the middle
- 1 connector (green)
Connecting the beam to the knee frame
Push the flat wooden end of the T-frame into the sheet metal holder mailed to the knee support. This is easiest when you turn the kneeframe crosswise to the T-frame.
Hammer tight the wedge to fix knee frame to T-frame
Shift the thin end of the wedge into the metal holder of the knee beam and push it tight. Check it the knee frame sits does not lean out related to the T-frame. Then hit the wedge with a hammer until it is tight.
Shift in the stabilizer
Shift the stabilizer in the side stabilizer. Make sure the middle of the stabilizer fits accurate in the the metal part. The stabilizer is short to be able to lean over sideways for easier reaching out.
Best is when the stabilizer is made of a slightly bent stick.
Tighten wedge to fix side stabilizer
To tighten the construction, a wedge is attached. Put the wedge in the space between the stand and the metal, hammer on it until it is tight.
Shift in seat support
Shift the 30 cm beam on the other end of the knee support frame in the metal part. Make sure that the centre of the beam is in the middle of the metal part.
Tighten wedge to fix seat support
Again, attach a wedge to tighten the construction.
Mount stick for knee supports
Shove one part of the green connector on the remaining end of the beam with metal end. Put the knee support stick between the two green parts. Now shove the second part of the green connector on the beam.
Tighten wedge to fix knee support stick
Attach the last wig to tighten this construction.
Assemble knee and seat cushions
Each of the blue knee and seat cushions consists of a 2-cilinder supporting part, foam and folded soft cotton. Assemble these parts for each of the four bags.
Insert support and cushion in bag
Put the cotton and the foam on the 2-cilinder support and put it in each bag.
Tight fit of bag holds foam in place

Shift the knee and seat units on the sticks
Shift the bags on each end of the knee and seat units. Two bags at the two ends of the seat, and two bags to support your knees.
Cushened supports all in place
You can push the cushioned support in place. This is how it should look like. Knot the rope to tighten the bags.
Ready to sit down
With your knees against the knee support you should sit in balance on the middle of the seat. To correct undo the wedge and shift and fasten the knee frame in a better position, same for the height of the knee support. Try different positions until you find one that is comfortable, also during work.
Try it out! This will cost you only a few moment but safe you a lot of stress.
