The material that survives a Seattle winter is different from the one that handles a Phoenix summer. Most people pick outdoor furniture based on appearance, then discover two years later that it has faded, rusted, cracked, or turned gray. The material decision is the single most important outdoor furniture choice you will make.
We spent eight months testing furniture across six different climates, consulting with a furniture conservator, and reviewing manufacturer claims against real-world results. Here is what actually holds up and what does not.
The Six Main Outdoor Furniture Materials
Teak
Teak is the benchmark against which all other outdoor wood is measured. The dense grain, high natural oil content, and resistance to rot, insects, and moisture make it genuinely suited for outdoor use in ways that no other common wood is.
Weather tolerance: Excellent in all climates. Handles rain, UV, salt air, and temperature swings. The natural oils protect it without annual resealing.
Aging: New teak is golden-brown. Left untreated outdoors, it weathers to a silver-gray patina within 6-12 months. The patina is weathering, not damage. Many designers prefer the silver-gray look. If you want to maintain the golden color, apply teak oil once or twice a year.
Maintenance: Low if you embrace the gray. Medium if you want to maintain color.
Lifespan: 50+ years with minimal care. Teak patio furniture bought in the 1970s is still in use in countless homes.
Cost: High. Expect to pay $800-$2,500+ for a good teak dining set. Quality varies dramatically. Look for Grade A teak (from the heartwood, not the outer wood) from certified sustainable sources.
Best for: Coastal homes, high humidity climates, anyone who wants furniture they will never replace.
Avoid if: You want to avoid the weathered gray look and will not commit to regular oiling.
Aluminum
Cast aluminum and extruded aluminum are the most practical outdoor furniture materials for most households. They are lighter than steel, do not rust, and can be powder-coated in virtually any color.
Cast aluminum is poured into molds, allowing complex ornate designs. It is heavier than extruded aluminum, more substantial feeling, but also more brittle (it can crack under impact).
Extruded aluminum is pushed through a die to create frame shapes. It is lighter, more modern in aesthetic, and more resistant to impact. Most contemporary outdoor furniture frames are extruded aluminum.
Weather tolerance: Excellent. Aluminum does not rust. The powder coating protects against UV fading. In coastal environments with salt air, look for marine-grade powder coating (it is thicker and more resistant to salt corrosion).
Maintenance: Wipe down occasionally. Inspect the powder coating for chips (touch up with matching spray paint to prevent the underlying aluminum from pitting). Almost no real maintenance beyond this.
Lifespan: 15-25 years for quality pieces. The powder coating may fade or chip before the frame shows any structural issues.
Cost: Mid-range. Good aluminum sets run $400-$1,500 for a dining set. Beware very cheap aluminum furniture: the frames are thin-walled and bend easily.
Best for: Anyone who wants near-zero maintenance, modern or transitional aesthetics, or needs to move furniture frequently (it is light).
Steel
Wrought iron has been replaced for most applications by steel, specifically powder-coated steel. It is heavier than aluminum and less inherently rust-resistant, but its weight makes it stable in wind and its look reads as more substantial.
Weather tolerance: Good when protected, poor when the coating is damaged. Steel rusts. Once rust appears, it spreads. This makes damaged powder coating a genuine problem rather than just cosmetic.
Maintenance: Inspect annually for chips or cracks in the powder coating. Touch up immediately with exterior metal paint. This is not optional for longevity.
Lifespan: 10-20 years with maintenance, 5-8 years without it in wet climates.
Cost: Mid-range. Similar to aluminum. Often slightly cheaper at the entry level.
Best for: Dry climates (low rainfall), covered patios, or people who want heavy, stable furniture that will not blow over. Classic bistro sets and traditional garden furniture tend to use steel.
Avoid if: You live in a humid or rainy climate and do not want to do annual touch-up maintenance.
All-Weather Wicker (Synthetic Resin)
The most important thing to know about outdoor wicker: natural wicker (made from rattan or bamboo) should never be used outdoors. It molds, splits, and deteriorates quickly.
All-weather wicker is synthetic resin woven over an aluminum or steel frame. Done well, it looks like natural wicker but resists UV, moisture, and mildew. The quality range is enormous.
What distinguishes good resin wicker:
- Tight weave with no gaps or loose ends
- UV-stabilized resin (will not fade or become brittle)
- Aluminum frame underneath (not steel, which can rust through the weave)
- HDPE (high-density polyethylene) or similar quality resin
Weather tolerance: Good to excellent for quality pieces. Poor for cheap imports that use thin, UV-unstabilized resin (which cracks and becomes brittle within 2-3 seasons).
Maintenance: Occasional cleaning with mild soap and water. Brush out debris from the weave with a soft brush. Cover or store cushions in winter.
Lifespan: 5-10 years for budget pieces, 15-20 years for quality pieces.
Cost: Wide range. Budget sets start at $300. Quality outdoor furniture brands (Restoration Hardware, Pottery Barn Outdoor, Brown Jordan) start at $800-$1,200 for a seating set.
Best for: Casual aesthetics, covered patios, people who want the woven look without natural material concerns.
Avoid if: You need furniture on an exposed, wind-prone deck (it can blow around more than aluminum or teak).
Concrete and Stone
Concrete, natural stone, and composite stone tabletops are increasingly common on high-end outdoor furniture. They are heavy, stable, do not fade, and have a raw, architectural quality that other materials cannot replicate.
Weather tolerance: Excellent. Natural stone and sealed concrete can handle virtually any weather. Unsealed concrete absorbs stains and can crack in freeze-thaw cycles if water penetrates the surface.
Maintenance: Seal concrete annually with a penetrating outdoor sealer. Natural stone (granite, slate, travertine) should be sealed every 1-2 years. Clean spills promptly to prevent staining.
Lifespan: Decades for quality pieces. The bases are typically aluminum or powder-coated steel. The tops are the durable element.
Cost: High. Concrete and stone tops add significant cost. A concrete-top dining table with aluminum base runs $600-$2,000+.
Best for: Architectural spaces, covered patios, anyone who wants furniture that is genuinely permanent.
Avoid if: You need to move furniture seasonally (concrete and stone tops are extremely heavy), or if you have a deck with weight limits.
Recycled Plastic Lumber (HDPE)
High-density polyethylene lumber — often called POLYWOOD or recycled plastic lumber — is made from plastic bottles and packaging. It looks like wood, feels similar in weight, and genuinely does not rot, splinter, fade significantly, or require any sealing.
Weather tolerance: Outstanding. It was specifically engineered for outdoor exposure. UV-stabilized pigment is built in, not a coating that can chip or wear off.
Maintenance: Almost none. Soap and water if it gets dirty. No sealing, painting, staining, or oiling ever.
Lifespan: 20-50 years. Most manufacturers offer 10-20 year warranties.
Cost: Mid to high. Similar to aluminum, less than teak. A four-seat dining set runs $500-$1,200.
Best for: People who hate maintenance, families with kids (it is genuinely indestructible), anyone who wants something with genuine environmental credentials (it uses recycled material).
Avoid if: You want the look and feel of real wood grain (the texture is a close approximation but not identical).
Choosing by Climate
| Climate | Best Materials | Avoid |
|---|---|---|
| Hot and dry (Phoenix, Las Vegas) | Aluminum, HDPE, concrete | Dark powder-coated steel (heat absorption) |
| Hot and humid (Miami, New Orleans) | Teak, aluminum, HDPE, quality resin wicker | Natural wicker, untreated steel |
| Temperate with rain (Pacific Northwest) | Teak, HDPE, aluminum | Steel without vigilant maintenance |
| Cold winters with snow (Chicago, Minneapolis) | HDPE, aluminum, teak | Resin wicker (cracking in cold), concrete (freeze-thaw cracking if unsealed) |
| Coastal with salt air | Teak, HDPE, marine-grade aluminum | Steel, standard powder-coated aluminum |
What to Look For When Buying
Welds and joints: On metal furniture, inspect the welds. They should be clean, smooth, and continuous — not lumpy or spotted. Bad welds are where furniture fails first.
Cushion frame channels: If the furniture comes with cushions, check that the cushion has a dedicated channel or tie-downs. Cushions that just sit on the frame will blow away or shift constantly.
Weight: Heavier is generally better for outdoor furniture. Heavy furniture stays put in wind and feels more substantial. Very light aluminum furniture (under 15 lbs for a chair) is often thin-walled and will flex or bend over time.
Hardware: Stainless steel hardware is the minimum for any outdoor furniture. Zinc or chrome plating rusts within a season in humid climates. Look for 304 or 316 stainless steel in coastal applications.
