Measuring Help

Include photos or diagrams showing how to measure for:

• Length
  
• Width
  
• Thickness
  

These visuals will help customers send accurate dimensions. Please design a simple 3-section input on the product page for customers to fill in:

1. Length (mm)
   
2. Width (mm)
   
3. Thickness (mm)
   

These dimensions should calculate the total cost live based on selected option (cover only or cover + foam).
