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 available at any hardware store. Choose teak for longevity. Choose cedar for budget. Both are proven outdoor furniture woods.
Cedar vs Teak — Side by Side
| Factor | Western Red Cedar | Teak |
|---|---|---|
| Outdoor lifespan | 10–20 years | 25–50 years |
| Natural rot resistance | Good | Exceptional |
| Water resistance | Moderate | Exceptional |
| Maintenance | Annual/biannual finish | Minimal — optional |
| Can be left untreated | No — deteriorates | Yes — turns silver-grey |
| Cost per board foot | $3–$6 | $20–$40 |
| Ease of working | Excellent — soft, easy | Moderate — dense |
| Availability | Any hardware store | Specialty dealers |
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 potentially rotting at the joints by year 5.
Why Cedar Is Worth Considering
At $3–$6 per board foot, cedar costs what teak charges per linear inch. It's at every hardware store in standard sizes, works easily with basic tools, and has genuine natural rot resistance from its aromatic oils. Maintained properly — exterior oil every 1–2 years — cedar outdoor furniture is a real 15-year investment. That's a legitimate choice, especially when a full cedar dining set in materials costs less than a single teak plank.
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 keep golden colour |
| If you skip it | Greys, checks, begins deteriorating | Turns silver-grey — still structurally sound |

Which Should You Choose?
Choose teak if: You want to build once and not think about maintenance. Budget is not the primary constraint. You want furniture that genuinely lasts a lifetime.
Choose cedar if: You're working to a tight budget. You're happy to oil the furniture each spring. You want materials available at any hardware store today.
