Teak Garden Furniture: The Complete Buyer's Guide

Teak has been the gold standard for outdoor furniture for centuries—and for good reason. Its unique combination of beauty, durability, and near-zero maintenance makes it the only wood that truly thrives outdoors year-round.

Origins & Sustainability

True teak (Tectona grandis) is native to Southeast Asia—Myanmar, Thailand, Laos, Indonesia. Today, Indonesia's state-managed plantations (Perhutani) supply most commercial Grade A teak under strict SVLK certification, ensuring legal, sustainable harvest. Avoid "teak" from Africa or South America—it's usually a different species (Gmelina, Acacia) with inferior properties.

Why Teak Outperforms Every Other Wood

Property	Teak (Grade A)	Cedar / Redwood	Pressure-Treated Pine
Natural decay resistance	Excellent (high oil, silica)	Good	Chemical-dependent
Insect resistance	Excellent	Moderate	Chemical-dependent
Dimensional stability	Excellent (low shrinkage)	Good	Poor (warps, checks)
Maintenance required	None (optional sealer)	Annual stain/seal	Annual stain/seal
Lifespan outdoors	50–75+ years	15–25 years	10–15 years

Grade A vs. B vs. C: What You're Paying For

Grade A (Heartwood only): Golden-brown, tight straight grain, high oil, no knots. The only grade for heirloom furniture.
Grade B (Heartwood + some sapwood): Color variation, lower oil, occasional knots. Shorter lifespan.
Grade C (Sapwood): Pale, soft, no natural oils. Often dipped in chemicals to mimic Grade A. Avoid.

Color Change: Feature, Not Flaw

Unsealed teak weathers to a distinguished silver-gray patina in 6–12 months. This is purely cosmetic—the wood remains structurally sound. To retain honey tones, apply a quality teak sealer (not oil) annually. Never use teak oil—it feeds surface mold and creates a sticky film.
