FoamTouch 3x24x72 High Density Foam
FoamTouch 3″x24″x72″ is a high-density polyurethane foam noted for its strong recovery and fire retardant properties. The 3-inch thickness makes it suitable for larger cushions, furniture seating, and boat or car cushions. Its durability supports everyday seating use and interior upholstery projects where long-term shape retention matters.
The foam’s size—3″ thick, 24″ wide, 72″ long—fits many standard cushion frames and is easy to cut to fit custom shapes. The product is marketed for oval and round poker tables, but it translates well to a range of upholstery and cushioning applications, including DIY projects. While not a low-density option, its higher density improves resilience and reduces compression over time.
Key considerations: ensure compatibility with existing cushions or frames, plan for material waste when cutting, and consider cover choices that accommodate a firm yet comfortable seating feel. The foam’s fire-retardant claim can also be beneficial for indoor use and compliance with certain upholstery standards.

This versatility is valuable for designers who need exact dimensions and tailored support, whether upgrading an old sofa, building a custom seat, or creating specialty cushions for vehicles or boats. It’s important to align density with intended use and to plan cutting and edging accordingly for clean, durable results.
Buying Guide: Key Purchase Considerations For Polyurethane High Density Foam
- Density and firmness: Higher density foams resist sagging and maintain shape under repeated use. Consider the desired firmness for seating versus cushioning or packaging.
- Thickness and dimensions: Match foam thickness to the intended cushion depth and frame dimensions. Cut-to-size options can reduce waste but require precise measurements.
- Open-cell vs closed-cell: Closed-cell foams resist moisture and are generally more durable for upholstery and outdoor use. Open-cell foams are often softer and better for sound absorption or packaging that requires more compression.
- Cutting and finishing: Some products are designed for easy cutting with standard tools. Plan for edge finishing, seams, and fabric overlays to achieve a clean, professional look.
- Durability and resilience: Look for phrases like “high density,” “long-lasting,” and “recovery after compression” to gauge long-term performance in cushions and furniture.
- Compatibility with coverings: Ensure fabric or vinyl overlays are compatible with the foam’s density and recovery characteristics to avoid premature wear or sagging.
- Special applications: For marine, packaging, or soundproofing needs, verify resin compatibility, cure characteristics, and specific performance metrics like ILD or compression strength if available.
- Environmental and safety: Check for fire retardant ratings and any certifications relevant to your project or local regulations.
In summary, selecting the right polyurethane high density foam depends on the intended use, the required firmness, and the project’s dimensions. The products highlighted here provide a spectrum of options—from standard upholstery cushions to cutting-edge cut-to-fit sheets and specialized foams for marine and packaging applications. Consumers should compare density, thickness, and cutting ease to arrive at a foam that delivers consistent comfort and lasting performance for their specific project needs.
