How to Choose the Best Material for Outdoor Furniture

Choosing the best material for outdoor furniture is a matter of research and education, and most people skip the research entirely. They go by looks in the showroom, bring something home, and discover three winters later that the powder coat is peeling or the leg joints have gone orange. Good news: the research takes about 20 minutes. There are eight materials that matter, and by the time you finish here, you'll know exactly which one fits your space, your climate, and your honest maintenance schedule.

We've been selling outdoor furniture since 2007, which gives us a front-row seat to what holds up and what doesn't. The methodology below draws on that experience, and it's part of the process we cover in our full patio furniture buyer's guide, though this piece goes deeper on material science and the climate factors that most guides skip entirely.

Use the quick-reference answers above if you already know what you're looking for. For the full breakdown (including our scoring methodology, climate-specific guidance, and a "best for" decision matrix), read on.

How We Score These Materials

The table below scores eight outdoor furniture materials across eleven criteria. Each criterion is scored 1 to 5, for a maximum of 55 points per material. We've been using a version of this framework since the early days of the store, and we've refined it as we've watched materials perform (and fail) over time.

A few things worth knowing before you look at the totals. First, the criteria are weighted equally, which is a simplification. In practice, Low Maintenance and All Weather are probably worth more to most buyers than Wind Resistant or Comfortable (since most people use cushions). Second, Wind Resistant scores heavier materials higher (wrought iron doesn't blow away in a gust), so the scoring is accurate, but don't read a low wind-resistance score as a fatal flaw for aluminum. Anchoring a lightweight piece is a $20 fix.

Here's what each criterion actually measures:

• Easy to Rearrange — how portable the material is; lighter scores higher
• All Weather — overall performance across rain, UV, humidity, and temperature extremes
• Wind Resistant — how well it stays put without anchoring; heavier scores higher
• Fade Resistant — how well the color and finish hold up under UV exposure
• Water Resistant — surface water repellency and resistance to moisture damage
• Rust Proof — resistance to oxidation and corrosion
• Aesthetically Pleasing — design range, visual appeal, available styles
• Comfortable — bare-seat comfort without cushions
• Durable — structural longevity under average care
• Low Maintenance — time and money required to keep it in good condition
• Price — value score (5 = affordable/best long-term value; 1 = expensive/poor value)

PRO TIP: A high total score does NOT mean "best for you." It means best across an average of all these needs. Climate and use case are personal multipliers the table can't capture. Read the "Best For" section at the bottom before you decide.

The Materials, Scored

The Full Breakdown

Scores tell part of the story. Here's what the numbers can't capture.

Aluminum: Cast, Extruded, and the Difference That Actually Matters

Aluminum is the most versatile outdoor furniture material available, and it's the backbone of the industry for good reason. It doesn't rust, doesn't require seasonal storage, holds a powder coat finish without peeling or chipping, and comes in a remarkable range of styles from traditional cast scrollwork to clean modern extrusions. The 15-year structural warranties our aluminum brands offer are among the best in any furniture category.

The cast vs. extruded distinction matters more than most guides acknowledge. Cast aluminum is made by pouring molten metal into a mold: it produces thicker walls, ornate detailing, and the classic "wrought iron look" without the weight. Extruded aluminum is pulled through a die into specific cross-sections, giving you cleaner lines, lighter weight, and a more contemporary aesthetic. Both are durable; they just serve different design directions. If you're going transitional or traditional, cast. If you're going modern or Scandinavian-influenced, extruded.

Quality varies significantly across brands. Wall thickness, alloy grade, and powder coat application all affect how a piece holds up over a decade. Buy from manufacturers with documented histories: the longer a brand has been making aluminum furniture, the more refined their process. Our aluminum buying guide goes deep on what to check before you buy. When you're ready to shop, our aluminum patio furniture collection covers everything from dining sets to deep seating, in both cast and extruded profiles.

PRO TIP: For coastal use, ask specifically about the powder coat process and frame construction. Look for "fully welded" frames: hardware joints (nuts and bolts) are the first place rust develops, even on aluminum. A fully welded aluminum frame eliminates that vulnerability.

Synthetic Resin Wicker: HDPE vs. PVC, and Why It Changes Everything

Synthetic resin wicker is the most popular outdoor material in the residential market, and the reason comes down to a combination of comfort, style range, and low maintenance that nothing else quite matches. The caveat is that "resin wicker" describes two very different products: HDPE wicker and PVC wicker.

HDPE wicker holds its color, resists UV degradation, doesn't unravel or crack, and is recyclable at end of life. PVC wicker looks the same when new, but it becomes brittle in UV exposure, cracks, unravels, and fades within a few seasons. The quality furniture we carry uses HDPE wicker on aluminum frames; that aluminum frame quality is inseparable from how the piece performs overall. A cheap aluminum frame will flex and weaken before the wicker does.

The design range in resin wicker is remarkable: more styles, profiles, and configurations available here than in any other category. From Hampton-style deep seating to contemporary sectionals to bar sets. Our guide to the best outdoor wicker brands breaks down which manufacturers are worth the investment.

Poly Lumber (HDPE Composite): The Material Getting Smarter Every Year

Poly lumber is made from 100% recycled high-density polyethylene: milk jugs, detergent bottles, shampoo containers. POLYWOOD processes roughly 400,000 of those containers per day at their Indiana and North Carolina facilities. By the time it's a chair on your patio, your laundry detergent jug has gone through a pretty dramatic career change.

The material's practical advantages are substantial. It can't absorb moisture, which means no rot, no swelling, no mildew. It won't splinter. The color runs through the entire board (not a surface coating), so it can't peel or chip. And it requires nothing beyond soap and water to maintain. POLYWOOD offers a 20-year residential warranty on their lumber, the longest in the category. Berlin Gardens and Seaside Casual offer comparable durability in this material category.

There are two honest drawbacks. First, poly lumber furniture gets warm in direct sun; the HDPE absorbs and holds heat in a way that lighter-colored aluminum doesn't. This matters on south-facing patios with full-day sun exposure. Second, the look has improved dramatically over the past decade, but on close inspection it still reads as synthetic to a trained eye. For buyers who want the warmth of wood without any of the maintenance, it's the best trade-off available. Our guide to poly lumber furniture covers the material in detail, and you can browse the full range in our poly lumber outdoor furniture collection.

Teak: The Most Complicated Relationship in Outdoor Furniture

Teak has been called "the king of woods" by so many people in this industry that the phrase has become a little threadbare. But the reputation is earned. Teak produces natural silica and oils within its own cellular structure that create a built-in barrier against moisture, decay, and insect damage. That's not a feature added during manufacturing. It's in the wood. A well-maintained teak piece can last 50 years outdoors. That's a legitimate claim, not marketing copy.

The complication is the patina. Untreated teak oxidizes to a silver-grey color within one to two seasons. Many people love this look; others buy teak expecting the warm honey color to stay indefinitely and are surprised when it doesn't. If you want to maintain the original color, you'll need to apply teak oil or sealer every season (or every other season at minimum). It's not an enormous time commitment, but it is a real one.

I have a Harmonia teak club chair set that's been sitting in my Denver backyard for ten years. Colorado sun is punishing: 300 days of it per year at altitude, which amplifies the UV intensity. I have never once oiled it, treated it, or done anything beyond occasionally rinsing it off. It silvered years ago, which took some getting used to honestly. But it is still as structurally solid as the day we got it, and I still sit in it regularly. For a material story, that's not nothing.

For responsible sourcing, look for FSC-certified teak, which confirms the wood comes from sustainably managed forests rather than old-growth sources. Our full teak buyers guide covers grain grades, sourcing, and care in detail. Browse our teak outdoor furniture collection for current inventory.

PRO TIP: The more intricate the design, the more surface area you're committing to maintaining. A simple teak bench takes five minutes to oil. A six-piece dining set with detailed arm profiles takes considerably longer. Factor that into your decision.

IPE Wood: For People Who Mean It

IPE (pronounced "ee-pay") is a Brazilian tropical hardwood sometimes called ironwood or Brazilian walnut, and the ironwood nickname is not casual. Its Janka hardness rating sits around 3,680, roughly three times harder than teak and significantly harder than most domestic hardwoods. It is practically impervious to dents, rot, insects, and weathering. Decking boards made from IPE can last 40 to 75 years outdoors with proper care.

The trade-offs are real. IPE is dense and heavy: expect a large dining table to run 80 to 120 lbs. Moving it is a two-person job. The density that makes it so durable also means it requires a specialized penetrating oil (not standard teak oil) to prevent surface checking (small surface cracks from moisture cycling). That oil is harder to find and harder to work with than standard teak care products. IPE furniture is also expensive, reflecting both the material quality and the demand for a slow-growing tropical hardwood.

The right application for IPE is a fixed, prominent piece where you want something that will outlast your ownership of the house: a built-in bench, a statement dining table on a covered terrace, a poolside chaise on a property that won't be rearranged. Browse our IPE wood furniture collection for available options.

Wrought Iron: Old School, With One Catch

The word "wrought" means "worked by hand," and historically that's exactly what it was: iron hammered and worked into shape while hot, creating the ornate scrollwork designs you still see on patio sets today. True historical wrought iron actually contains a slag content that made it less brittle than cast iron. Most furniture sold as "wrought iron" today is mild steel that's been decoratively formed to look hand-worked; the original process is essentially extinct as an industrial practice, which is either a loss for craftsmanship or a relief for anyone who's ever tried to carry one of these chairs across a patio.

Where wrought iron furniture genuinely excels is on a covered patio where it won't be moved often, in a dry climate, where you want an heirloom aesthetic that nothing else replicates. The ornate designs are distinctive, and the weight (typically 20 to 40 lbs per chair) means wind isn't a concern.

The one catch is the coating. Wrought iron will rust the moment moisture finds bare metal. A chip in the powder coat, a scratched weld joint, hardware that wasn't sealed properly: any of these is an invitation for oxidation that spreads. In damp climates or anywhere near salt air, wrought iron requires regular inspection and touch-up of any damaged finish. You can browse the full range in our wrought iron patio furniture collection.

Powder-Coated Steel: Strong, Heavy, and Rarely the Right Choice

Steel is the strongest material on this list. It's also the most rarely justified for residential outdoor furniture. For most applications, aluminum delivers comparable structural performance at a fraction of the weight and with better rust resistance. Unless you're outfitting a commercial installation where weight is an asset and durability across heavy public use is the primary spec, steel outdoor furniture is a solution to a problem most patios don't have.

If you do buy steel outdoor furniture, the most important factor is what's under the powder coat. Look for galvanized steel, which adds a zinc barrier between the steel and any moisture that gets through the coating. Without galvanization, a single chip in the finish becomes a rust initiation point that spreads under the coating and is very difficult to stop. Steel outdoor furniture in coastal environments or high-humidity climates accelerates this problem considerably.

Steel makes more sense for commercial settings: restaurant patios, hotel pool decks, public spaces where the added mass keeps furniture in place and the high-traffic wear patterns benefit from the greater structural margin. For residential use, aluminum almost always wins the cost-performance calculation.

Rope and Woven Synthetic: The Comfort Wild Card

Rope furniture (also called cord, synthetic rope, or woven synthetic) is not a structural frame material in the way aluminum or teak is. It's a surface treatment applied over aluminum frames, and the distinction matters for how you evaluate it. You're not really buying a rope chair; you're buying an aluminum chair wrapped in rope. The frame is what lasts; the rope is what you sit in.

That said, rope furniture earns its high comfort and aesthetics scores. The woven surface conforms slightly, dries fast after rain, requires no cushions for comfortable seating, and has a contemporary coastal aesthetic that's become very popular in both residential and hospitality settings. There's a texture and warmth to it that you don't get from bare aluminum.

The honest durability caveat: quality rope weaves will hold up for years, but they degrade before the frame does. UV exposure and repeated flexing break down synthetic cord over time, and cheaper weaves can stretch or develop weak points in high-use areas. Buy from brands with track records and, if possible, with a warranty that covers the weave, not just the frame. Our rope outdoor furniture collection covers several well-regarded options in this category.

What the Scores Don't Tell You: Climate

The scoring table is geography-blind, and that's its main limitation. A set that scores 47 in San Diego can be a maintenance nightmare in coastal Maine. Climate-specific selection is where most material guides fall short, so we've broken it out here.

Coastal and Salt Air Environments

Salt air is corrosive. It accelerates oxidation in iron and standard steel, compromises powder coat adhesion over time, and can pit aluminum that isn't properly specified for coastal use. The materials that belong near the ocean are poly lumber (immune to corrosion entirely, with nothing in it to corrode), marine-grade aluminum (fully welded frames, powder coat formulated for salt exposure), and HDPE resin wicker on aluminum frames.

Wrought iron and steel near the ocean are poor long-term investments regardless of initial coating quality. Teak can work at the coast if you're committed to maintenance, but the salt air accelerates the silver patina and increases the frequency of oiling needed to keep the wood from checking. IPE is similarly fine structurally but needs more frequent oil applications than it would inland.

The specific ask for coastal aluminum: fully welded frames. Hardware joints (the nuts, bolts, and fasteners that hold non-welded frames together) are typically made from multiple metal types and are the first corrosion point, even on pieces advertised with "stainless steel hardware."

Intense Sun and High UV

High UV environments accelerate fade on any material with a surface-applied color. Poly lumber is the exception: the color is integral to the material, so UV degrades the surface texture slightly over many years but doesn't cause color loss. HDPE wicker (not PVC) also holds color well under UV.

Metal furniture gets hot in direct sun, which matters for comfort more than durability. Lighter powder coat colors absorb less heat; a white or sand-colored aluminum chair in direct sun is noticeably more comfortable than a dark charcoal one. Teak in high UV will silver faster than in moderate climates and will need more frequent oiling if you want to maintain the warm color.

My Denver set is a useful data point here. Colorado gets intense, high-altitude UV (more than most coastal locations) and the teak silvered faster than it would have in a lower-UV environment. It held structurally, but the aesthetic change was accelerated. Factor that into any teak purchase in mountain or desert climates.

Cold Climates and Freeze-Thaw Cycles

Poly lumber is explicitly designed for this. The HDPE material expands and contracts with temperature cycles without cracking or warping; POLYWOOD and Berlin Gardens both document that their furniture can be left outdoors year-round in any climate, including northern winters with repeated freeze-thaw cycles. No other material makes that claim as cleanly.

Aluminum handles cold well with no special precautions. Teak and IPE are structurally fine through freezing temperatures, though moisture in any open checking or cracking can expand in a hard freeze and worsen existing damage; teak care is more important before winter than after. Wrought iron and steel should be inspected for any coating damage before winter; exposed metal plus water plus freeze-thaw is a corrosion accelerant.

High Humidity

Humidity is primarily a problem for natural wood. Both teak and IPE need more frequent maintenance in persistently humid climates because the wood is cycling between wet and dry states more actively. Mold and mildew are more likely on untreated teak surfaces in humid conditions. Aluminum, poly lumber, and resin wicker are unaffected by ambient humidity. For any material, cushion storage in humid climates matters: even Sunbrella fabric, which is highly mold-resistant, will develop surface mildew if stored damp in a closed container.

The "Best For" Quick Reference

As with any real question, the answer to "which material is best" is a form of "it depends." But here's how we'd actually direct someone walking into the showroom. You can also browse our collection organized by material to see what's available in each category.

Materials That Don't Hold Up Outside

A few materials appear in outdoor furniture retail that we'd steer you away from:

Cheap plastic resin furniture (the stackable white chairs and basic patio sets you find at big-box stores) is inexpensive for a reason. The polypropylene used in mass-market plastic furniture becomes brittle under UV exposure, fades badly, and provides almost no structural resilience. Fine for temporary use. Poor investment for anything you expect to last more than a couple of seasons.

PVC wicker mimics HDPE wicker at first glance, and the price difference is the biggest tell. PVC becomes brittle in UV exposure, unravels, cracks, and isn't recyclable the way HDPE is. If the material spec doesn't explicitly say HDPE or all-weather HDPE wicker, assume it may be PVC.

Natural rattan is an indoor material. It gets used outdoors in old photographs because people would bring their rattan furniture outside for the afternoon and bring it back in. Left outdoors in any climate (especially humid ones), natural rattan degrades quickly.

Bare metals of any kind (untreated steel, uncoated aluminum, raw cast iron) will rust on contact with moisture. This seems obvious, but it's worth stating: any metal outdoor furniture should have a protective coating (powder coat, anodizing, galvanizing) and that coating is the thing you're maintaining when you inspect the piece annually.

A Word on Fabric and Cushions

Outdoor cushion fabric is a material decision too, and it compounds whatever you chose for the frame. We always recommend Sunbrella fabrics when the option is available. The reason is specific: Sunbrella uses a solution-dyed acrylic process where the color is applied at the fiber stage, before the fabric is woven, rather than printed onto the surface of a finished fabric. This means UV exposure fades the surface and the interior of the fiber at the same rate: there's no "bleached out top, dark interior" that you see in cheaper printed fabrics after a season.

Sunbrella's marine origins are also worth understanding. The brand started making canvas for boat applications and expanded to furniture. The durability requirements for marine canvas (constant sun, salt water, mildew exposure) are significantly more demanding than residential patio use, and those standards carry over. It can be cleaned with a diluted bleach solution without color damage, which is useful for mildew spots.

When shopping for cushions, look for fabric with zippered covers (so you can remove and wash the cover separately from the foam) and foam that's either rated for outdoor use or has drainage holes. Indoor foam soaks and stays wet; outdoor-rated foam or quick-dry foam dries from the inside out.

What We Actually Recommend

After 17 years of selling this, here's the honest answer.

For most residential buyers, particularly anyone who doesn't want to think much about maintenance, the combination of powder-coated aluminum furniture with Sunbrella cushions delivers the best long-term value in the market. You get a 15-year structural warranty, essentially zero maintenance (wipe it down occasionally, that's it), and a design range across brands like OW Lee, Castelle, Jensen Outdoor, and Ebel that covers everything from traditional cast to contemporary extruded. The cost-per-year numbers are very strong when you factor out the maintenance costs that other materials carry.

For buyers who prioritize absolute zero maintenance and appreciate sustainability, poly lumber is the right call. POLYWOOD's 20-year warranty is the longest in the business, the material is genuinely made from recycled content, and it can stay outside in any climate without any action required. It's not cheap upfront, but it's the most cost-effective choice measured over 20 years. Berlin Gardens offers similar quality with a slightly different aesthetic range.

For buyers who want real wood and accept the relationship that comes with it: teak, full stop. IPE is more durable structurally, but teak is more available, lighter, better designed across the furniture market, and more forgiving in maintenance. My 10-year-old Denver set is proof that even neglected teak holds up well. If you commit to oiling it, it stays beautiful. If you don't, it turns silver and stays solid. Either way, you have furniture.

My personal preference for a covered patio anywhere in the country is cast aluminum with Sunbrella cushions in a neutral tone, something I can rearrange when I want to, leave out through winter, and basically ignore. The design variety in cast aluminum is remarkable. No matter your personal style or budget, there's a cast aluminum set that fits it. If you want help narrowing it down, reach out to our team.
