Buying Guide

Thickness matches cushion depth

Measure your cushion covers before buying—choices here include 4 in, 5 in and 6 in options to match seat depth and maintain cover fit

Check density and ILD for comfort

Look for listed density (pound) and ILD/firmness like the 36 ILD or 35 ILD examples to balance support and resilience for outdoor seating

Prefer CertiPUR or US-made labeling

CertiPUR certification and US-made products indicate indoor air quality and manufacturing standards that matter for longevity and safety

Cut and shape options for fit

Choose foam sizes that allow trimming or selecting longer widths (e.g., 24 x 72 in sheets) to accommodate oval, bench or custom-shaped patio cushions

Value vs. longevity trade-offs

Thicker, higher-density foams cost more upfront but retain shape longer; budget sheets work well for occasional-use furniture or covered patios
