6.7  Back

The back of the Skippi is attached to the seat frame with two bearing plates on the left and 

right. Each of the two bearing plates is attached to the seat frame with two screws and to the 

back with one screw. For loosening these three screws, use a size 5 Allen wrench and a size 

13 open-end wrench. Loosen the two screws on the seat frame on the left and right to remove 

the back. The fourth screw on the bearing plate serves as stop for the back angle adjustment.

Back upholstery
For replacing the back upholstery of the Skippi, simply pull it off the hook-and-loop straps and 

reattach the new upholstery to the straps.
For readjusting the back upholstery, remove the upholstery and readjust the hook and loop 

straps on the frame.
