Parametric S-Bench

I want to recreate the architectural parametric bench shown in the attached reference image. Analyze the image carefully and create a similar 3D model directly in Rhino using Grasshopper. The bench has the following characteristics: - An organic, flowing S-shaped curved form. - A long continuous sculptural seating structure. - Multiple parallel wooden ribs or slats following the entire curved shape. - Smooth rounded edges and soft transitions. - Two elongated white upholstered seating cushions integrated into the wooden structure. - A minimalist contemporary architectural design. IMPORTANT: Do not create a simple mesh or static imported object. Build the model using editable Rhino geometry and a parametric Grasshopper definition. Start by creating the main underlying S-shaped centerline and the overall bench geometry. Use millimeters as the unit system. Assume an approximate overall length of 4500 mm, width of 900 mm, and seating height of 450 mm. Keep all dimensions adjustable. First create the base geometry and explain the modeling structure before proceeding to the detailed wooden ribs.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
