Direct Answer: Teak is more durable (25–50 yrs vs 10–20 yrs) and needs far less maintenance. Cedar costs 4–6x less and is at any hardware store. Choose teak for longevity. Choose cedar for budget. Both are proven outdoor furniture woods.

Why Teak Wins on Durability
Teak contains natural silica and oils that actively repel water, resist fungal decay, and deter insects — working from inside the wood, not from a surface coating. A teak bench left completely untreated for 20 years turns silver-grey but stays structurally sound. The same cedar bench without maintenance would be checking and rotting at the joints by year 5.
Why Cedar Is Worth Considering
At $3–$6 per board foot, cedar costs a fraction of teak. It is at every hardware store in standard sizes, works easily with basic tools, and has genuine natural rot resistance from its aromatic oils. Maintained with exterior oil every 1–2 years, cedar outdoor furniture is a real 15-year investment.
Maintenance Compared
| Cedar | Teak | |
|---|---|---|
| Year 1 | Apply exterior oil or stain before first outdoor season | Nothing required |
| Ongoing | Re-apply every 1–2 years | Optional teak oil every 1–2 years to maintain golden colour |
| If you skip it | Greys, checks, begins deteriorating | Turns silver-grey — still structurally sound |

Which to Choose
Choose teak if: You want to build once and walk away. Budget is not the primary constraint.
