A = the total diameter of the curve across the top.
B = the height up the side before the curve begins.
Looking at the diagram:
Start with the flat vertical sides up to measurement B.
From that point, we begin the sweep of the curve.
The curve is formed using a radius equal to ½ of A.
This ensures the rounded top starts at the correct height and follows a smooth, even arc.
💡 For accuracy, measure from the cover or baseboard — old foam is usually compressed.
