How long do outdoor upholstery foam sheets last?
Outdoor foam is designed to handle moisture and outdoor conditions. With regular use, expect 5–10 years of performance, and up to 15 years with light or occasional use.
Can outdoor foam be left outside in the rain?
Outdoor foam resists moisture, but for best longevity it should be paired with a breathable, water-resistant fabric cover. Allow foam to fully dry if soaked.
What firmness should I choose for outdoor cushions?
Softer foams (ILD 25) work well for back cushions or occasional seating.
Medium firmness (ILD 33) is ideal for most outdoor seat cushions.
Firmer foam (ILD 45) is best for high-traffic seating or thicker cushions that need extra support.
