Pilates Mat Thickness & Spine Cushioning Calculator

Overview

A specialized, client-side web utility designed to help Pilates practitioners assess whether their current mat provides sufficient cushioning for their spine and joints based on their physical profile and exercise intensity. The tool uses a clear, high-contrast, light-mode interface to provide immediate recommendations for mat upgrades or supplemental support.

Core Features

• Dynamic Assessment Engine: Users input mat thickness (mm), weight range, and primary exercise type to receive a real-time cushion safety score.
• Visual Cushioning Gauge: A CSS-animated circular progress or bar gauge that indicates the "Safety Rating" (e.g., Safe, Recommended Enhancement, High Risk).
• Actionable Recommendations: Dynamic output explaining why a setup might be insufficient (e.g., "For spinal rolling, your 3mm mat is likely too thin. Consider adding a travel pad or switching to a 6mm+ high-density mat.").
• In-Memory Calculations: All logic is processed in RAM. No cookies or local storage.
• Responsive Design: Optimized for mobile phones (perfect for use while at the studio) and desktop browsers.

UI Layout & Design

• Header: Simple, clean application title with a descriptive tagline.
• Input Section:
  • Dropdowns/Sliders for Mat Thickness (3mm - 15mm).
  • Toggle switches for User Weight Class and Sensitivity levels.
  • Radio buttons for Exercise Focus (Stretching, Core Rolling, Strength Training).
• Results Section:
  • Central gauge display indicating current cushioning adequacy.
  • Clear text box for advice based on results.
• Styling: Vibrant, professional light-mode aesthetic. Soft shadows (box-shadow), crisp borders, and accessible typography (Sans-serif, high legibility).
• Animations: Subtle transitions when toggling inputs; smooth fade-in for results updates.

Technical Directives

• Architecture: One single .html file. All CSS in <style> tags, all logic in <script> tags.
• Performance: Zero-dependency (or use CDN links for Tailwind CSS for layout speed).
• Constraints:
  • NO localStorage/cookies/IndexedDB.
  • NO dark mode toggle. Enforce white/light gray background scheme.
  • NO popups. Use embedded feedback modules.
  • All external links must have target="_blank" rel="noopener noreferrer".
• Accessibility: Use semantic HTML5 elements (<main>, <section>, <article>, <label>) to ensure screen-reader compatibility.
