Introduction: Flexiseat2018

Redesigned by Shane Schurm & Janne Cherlet

Shane Schurm and Janne Cherlet were appointed to make a design from 2010 parametric. This project, named Flexiseat, was designed by students at Howest in Belgium. This design arose from a problem
of a client. The aim of the assignment was not only to make the design parametric, but also to go through the entire process from the beginning until the end. This product was prepared to be published on instructables. This is a website that offers manuals to replicate products. We experienced this project as a challenge with some technical difficulties, but we are proud of the result we could achieve

Step 1: Get Files

You can find the files in the attachments. Choose the right age and a custom fit flexiseat will load.



- Download all files and put them in one folder.

- Open the mother part called Flexiseat.

- Tools/part_families/edit_spreadsheet/(make sure you have a excel based program)

- click the age you prefer

- click Add_ins/part_family/apply_values

Now your preferred part will be loaded.

Step 2: Get Materials

You can choose wich material you want to use. Keep in mind the weight of you material and the difficulty to fabricate.



- Make sure you link the right age of the person with the right CAD model.

- Make a 2D drawing with all parts.

- Buy a wooden plank with length and width closest to the dimension of you user defined 2D drawing.

We recommend to use 8mm plywood.

Step 3: Lasercut / Saw and Drill / Mill

You can make the seat like you want. Lasercutting and milling are the easiest ways. Are you more a old school type, take the challange on and take those tools



- Make a drawing of your user defined CAD parts and prepare it in a vector based program (e.i.Illustrator) for Lasercutting or milling depending of the software used for milling or lasercutting.

Not computer aided manufacturing


- Draw your dimensions on the plywood.

- Drill out the 4 mm holes.

- Saw your parts

Step 4: Assembly - Tools & Materials

for the assembly for your Flexiseat you will need materials and tools

Tools & materials

- textile band
- glue
- 2 nails (2x30)
- tongs
- the flexiseat parts.
- 3D printed pins
- 3D printed supports for the side parts

Step 5: Assembly - Connect the Back to the Seat With the Textile Band

Start sewing the 2 pieces together with the textile band.

Step 6: Assembly - Hold Pin

add a hold pin to hold the begin and and from the textile band

Step 7: Assembly - Cut

cut of the remaining textile band

Step 8: Assembly - Repeat

do this also for the other parts

Step 9: Assembly - Cut Out a Fabric Shape for the Straps

Step 10: Assembly - Sew or Glue the Velcro on the Fabric

Step 11: Assembly - Place and Glue the Pin

Step 12: Assembly - Glue the Velcro on the Wood

Step 13: Assembly - 3D Print the Slots

Step 14: Assembly - Lock the Slots

Step 15: Cut and Grind the Rest Off

Step 16: Flexiseat Complete
