Is an aluminum frame or wicker better for an outdoor sofa?

Specialist community consensus on r/homeowners and r/Costco leans strongly toward powder-coated or welded aluminum frames for longevity, with one self-described engineer praising welded aluminum construction and stainless hardware. All-weather resin (PE) wicker is popular for looks and is also rust-free when wrapped over an aluminum frame, but reviewers note the woven surface and cushions are the parts most likely to age. Steel frames can rust over time if the coating is scratched.
