|Back panel - Front panel positioning||Rotated with 45°to each other||Rotated with 45°to each other|
|Compression folding||Higher variation in repeatability. |
Can be reduced through folding seam.
|Cushion Volume||More cushion volume (depth) on the steering wheel rim but less radial coverage.|
Care must be taken with high column angles.
|Volume distributed into the width. |
Better steering wheel rim coverage
|Seam||Chain (looper) to be at back panel||Chain (looper) to be at back panel|
Seam stress becomes more critical on small sized cushions.
|Shape Side view||3-D’ with manual sewing process.||2-D’ with manual or automatic sewing process.|
|Shape Frontal view||Octagonal||Round|
|Steering column angle||0||Better for high column angles|
