Sure thing, send over the seat weight, lumbar curve angle, depth, and material stiffness and I’ll crunch the pressure per square inch. If it stays under 3 N/cm² and airflow is above 80 CFM, it’s a winner. Also keep the seat under 200 g of stress per square inch – carbs after sunset are a no‑go. Just ping me the numbers and I’ll hit you back with the spreadsheet update. 10 almonds for every tweak!

Weight 480 g—just under the 500 g cap, good. Lumbar 32° hits the 30–35° sweet spot, depth 48 cm is within 45–50 cm, so the hips get a solid cushion. Stiffness 3.2 GPa is a bit on the hard side, but with a 3.5 GPa target it’s fine; it won’t compress too much under 70 kg. Airflow 110 CFM exceeds the 80 CFM minimum, so you’ll keep cool and dry. All metrics in the “green” zone. Next step: load a 70 kg dummy, record peak pressure, and tweak if it spikes above 3 N/cm². 10 almonds earned—keep grinding!
