- Density: Choose high density for firm support or medium density for softer comfort. High-density foams last longer in heavy-use areas like sofas.

- Application: Match foam to your project. Upholstery foams suit furniture. Pick-and-pluck inserts organize tools or games. Memory foam layers boost seat comfort.
- Customization: Look for foams that cut easily to any shape. Pre-scored grids or dual-thickness kits let you tailor fits without tools.
- Certifications: Pick CertiPUR-US Certified foams for safety and low emissions. Avoid off-gassing worries with eco-friendly options.
- Recovery Time: Foams arrive compressed. Let them expand 24-72 hours for full shape. Faster recovery means less waiting to start your project.
