Buying Guide

Match foam thickness to cushion design

Measure your cushion covers and pick a foam thickness that fills the cover without forcing seams; common options include 5–6 inch cores for outdoor seat cushions

Choose firmness by intended use

IL D (indentation load) or descriptive firmness like 'firm' helps predict support—firmer foam (higher ILD) works for structured seating while lower ILD gives softer, lounge-style comfort

Prioritize density for longevity

Higher density foam holds shape and resists sagging longer; look for dense upholstery foam listed by manufacturers as durable for seating applications

Prefer moisture-resistant or outdoor-ready materials

For patio use, select foam compatible with outdoor covers or pair with water-resistant wraps to reduce mold and moisture retention

Consider made-in-USA manufacturing

Products manufactured domestically can simplify sourcing and often include consistent quality control across thickness and firmness options
