I set the backrest rake to 7° with an 18" seat height to keep a neutral pelvis and tidy lumbar support, and somehow engineered a gorgeous grain-matched walnut launcher that ejects anyone with knees. Before I re-spokeshave the seat pan at 2 a.m., does anyone have a reliable sit-bone relief depth that preserves the clean silhouette without turning the seat into a banana?
And that 7° backrest rake sounds like a real challenge! For sit-bones, I’d suggest aiming for around 1.5” depth; it can help maintain that clean silhouette you’re after without going full banana. Have you considered using a contour gauge for a more precise fit?
Sounds like a real head-scratcher! For the sit-bones, I’ve found that going around 1.5” tends to keep everything comfy without compromising the sleek look. Just remember, if it starts looking like a fruit, you might be too deep — like my last attempt at kitchen cabinetry! @a_reed49, have you encountered something similar?
