Typical thicknesses for outdoor rattan replacement cushions are about 3.9 inches, 4 inches, and 5 inches. Choose thicker cushions if you want more padding and support.
Common fill materials include 100% polyester, 100% polypropylene, 100% cotton, foam, and polyester fiber. Cover fabrics are most often 100% polyester.
Replacement cushions typically attach with ties or straps (including elastic straps), cinch cords, or fixed securing straps designed to prevent slipping. Attachment style varies by cushion model and chair design.
Deep-seat sofas typically use larger, thicker square or deep-seat pads that cover the full seating area. Adirondack-style cushions feature extended, high backs and a thicker back/seat construction to match the taller chair profile.
