Teak and other hardwoods last longest, often 15 to 20 years outdoors with minimal care

Teak is the gold standard for outdoor furniture longevity. It's a tropical hardwood with natural oils that resist rot, insects, and UV damage without needing sealant or paint. A teak chair or table left outside year-round will weather to a silvery gray but remain structurally sound for decades. Other durable hardwoods include cumaru, ipe, and shorea, though teak is the most widely available in North America.

The trade-off is cost—teak furniture runs two to four times the price of pressure-treated wood or metal alternatives. But if you're buying once and keeping it for 15 to 20 years, the per-year cost is often lower than replacing cheaper pieces every five to eight years. Hardwood furniture also requires almost no maintenance beyond occasional cleaning with a soft brush and water.

Key Takeaways

  • Teak and other tropical hardwoods last 15 to 20 years outdoors with no sealant needed, making them the longest-lasting option despite high upfront cost.
  • Aluminum frames with Sunbrella or solution-dyed fabric cushions last 10 to 15 years and resist rust, though cushions need replacing every 5 to 7 years.
  • Pressure-treated wood lasts 8 to 12 years if sealed every two years; untreated wood rots within 3 to 5 years in wet climates.
  • Wrought iron and steel rust quickly unless powder-coated; powder-coated pieces last 10 to 12 years if the coating stays intact.
  • Wicker and rattan, even synthetic versions, typically last only 5 to 8 years before frame or weave begins to fail.

Aluminum frames with quality outdoor fabric

Aluminum doesn't rust, which makes it a solid middle ground between cost and durability. A frame alone lasts 15 to 20 years, but most aluminum furniture comes with cushions or sling fabric, and those are what actually wear out. Sunbrella and other solution-dyed acrylic fabrics hold color and resist mildew better than standard outdoor cloth and typically last 5 to 7 years before fading or tearing noticeably.

The frame itself needs almost no maintenance—occasional soap and water is enough. The weak point is the joints where the frame is welded or bolted together; if those start to separate, the piece becomes wobbly and unsafe. Buying from a manufacturer known for solid construction (rather than the cheapest option) makes a real difference here. Expect to replace cushions or fabric slings every 5 to 7 years, which is cheaper than replacing the whole piece but still an ongoing cost.

Pressure-treated wood that's sealed regularly

Pressure-treated lumber resists rot better than untreated wood because it's been infused with preservatives. A pressure-treated wood table or bench lasts 8 to 12 years if you seal it every two years with a water-repellent stain or sealant. Without sealing, the wood absorbs moisture, and the preservatives gradually leach out, leaving it vulnerable to rot and splinters.

The sealing schedule is the real commitment here. If you skip it for three years, you'll likely see soft spots or visible rot by year five. In wet climates or areas with heavy shade (where wood dries slowly), the timeline shortens. Pressure-treated wood is affordable upfront—usually one-third to one-half the cost of teak—but the maintenance labor adds up. If you're not willing to seal it regularly, untreated wood will rot within 3 to 5 years, so the choice is really between sealed pressure-treated or a different material altogether.

Cast aluminum and powder-coated steel

Cast aluminum is heavier and more decorative than tube aluminum, and it also won't rust. It lasts as long as tube aluminum—15 to 20 years—but it's more expensive and harder to move. Powder-coated steel is cheaper than aluminum but requires the coating to stay intact; any scratch or chip exposes bare metal, which rusts quickly.

Powder-coated pieces last 10 to 12 years in most climates if the coating isn't damaged. In coastal areas with salt spray, that timeline shrinks to 5 to 8 years because salt accelerates rust even under the coating. Once rust starts, it spreads under the powder coat and is nearly impossible to repair without stripping and recoating the whole piece—a job that costs almost as much as a new chair. If you live near the ocean, aluminum is the better choice; if you're inland, powder-coated steel is acceptable if you inspect it yearly for chips.

Wrought iron and untreated steel

Wrought iron and steel furniture look beautiful but rust is inevitable without constant maintenance. Even "rust-resistant" steel will develop surface rust within a year or two outdoors. To keep it looking good, you'd need to wire-brush it, prime it, and repaint it every year or two—a labor-intensive process most people don't stick with.

If you do maintain it religiously, wrought iron can last 20 years or more. If you don't, it becomes unsafe—rust weakens the metal, and sharp edges develop where the coating flakes off. For most homeowners, wrought iron is a decorative choice that requires commitment. If you like the look but not the maintenance, cast aluminum or powder-coated steel in a similar style will last longer with far less work.

Wicker, rattan, and synthetic woven materials

Natural wicker and rattan are woven plant fibers that absorb moisture and break down outdoors, typically lasting only 3 to 5 years before the weave starts to separate or the frame rots. Synthetic wicker made from resin-coated polyethylene or polypropylene lasts longer—usually 5 to 8 years—because the material doesn't absorb water. However, UV exposure still degrades the resin coating, and the weave can loosen or tear.

Wicker and rattan are best suited to covered patios or seasonal use. If you leave them in full sun and rain year-round, expect visible wear within two to three years. They're also the least durable option for the price; you're paying for aesthetics, not longevity. If durability is your priority, aluminum or hardwood will serve you much longer.

Comparing total cost over time

The cheapest furniture at purchase isn't always the cheapest over a decade. A $300 wicker set lasting five years costs $60 per year. A $1,200 teak set lasting 18 years costs $67 per year—nearly the same, but with far less hassle. A $600 aluminum set with $100 in cushion replacements every six years costs roughly $100 per year if it lasts 15 years.

The real variables are your climate, how much sun and rain your furniture gets, and whether you're willing to do maintenance. In a dry climate with a covered patio, cheaper materials last longer. In a wet, sunny climate with year-round exposure, hardwood or aluminum pays for itself in reduced replacement cycles. Write down what you actually have space and time to maintain, then choose the material that matches that reality rather than the one that looks best in a showroom.

Frequently Asked Questions

Does teak need to be sealed or stained?

No. Teak's natural oils protect it without sealant. You can leave it unsealed and let it weather to gray, or explore teak oil every year or two if you prefer the golden color. Sealing it with polyurethane or varnish actually traps moisture and causes the finish to peel, so avoid that.

Can I leave cushions on outdoor furniture year-round?

Not if you want them to last. Cushions absorb moisture and develop mildew in damp climates, especially in winter. Store them indoors or in a waterproof box when not in use. Even Sunbrella fabric fades faster and can mildew if it stays wet for weeks. Removing cushions adds maybe two years to their lifespan.

What's the difference between outdoor fabric and regular upholstery fabric?

Outdoor fabrics are solution-dyed (color goes through the fiber, not just on the surface) and treated to resist mildew and UV fading. Regular upholstery fabric fades in weeks and mildews in damp conditions. If a cushion cover isn't labeled for outdoor use, it won't last more than a season or two outside.

Is it worth buying expensive patio furniture if I move in a few years?

Probably not. Teak and high-end aluminum are heavy and expensive to move, and you may not recoup the cost in resale. If you're renting or planning to move within five years, mid-range aluminum or sealed pressure-treated wood is a better bet—it's lighter, cheaper, and easier to replace if you can't take it with you.

How do I know if powder-coated furniture is good quality?

Look at the thickness of the metal frame and the smoothness of the coating. Cheap pieces have thin tubing that dents easily and thin coatings that chip quickly. Run your hand over the surface—it should feel smooth with no rough spots or drips. Check the welds or joints; they should be clean and even. If the price seems too low, the coating is probably thin.
