When you're trying to find the best wood for outdoor furniture, the conversation almost always lands on three top contenders: Teak, Cedar, and White Oak. These species bring a fantastic mix of natural resistance to rot and insects, which is exactly what you need for furniture that has to live outside. Your final pick will come down to balancing looks, the amount of upkeep you're willing to do, and your budget.
Investing in outdoor furniture isn't just about buying a table and chairs; it's about creating an extension of your home. The right wood can turn a simple patio into a genuine oasis, but the wrong one will lead to a warped, rotten mess in just a couple of seasons. It all boils down to understanding how different woods stand up to the elements, year in and year out.
This guide goes beyond the usual surface-level advice. We're going to dig into a detailed comparison that’s all about real-world performance, helping you make a choice you'll be happy with for years to come.
Before we jump into specific species, let’s get clear on what really matters. The best woods for outdoor projects all nail these key qualities:
There's just something about real wood. It brings a warmth and natural feel that synthetic materials just can't match. That appeal is a huge reason it dominates the home goods market.
People's love for authentic materials is as strong as ever. In the United States outdoor furniture market, wood holds a massive 46% market share, proving its lasting popularity for both its beauty and its performance. You can learn more about trends in the outdoor furniture market to see where things are headed.
To give you a quick starting point, this table breaks down the main differences between the most popular choices for outdoor furniture. We'll dive much deeper into each one later, but this gives you a solid overview to begin with.
| Wood Species | Primary Strength | Common Use Case | Budget Level |
|---|---|---|---|
| Teak | Unmatched rot and water resistance due to high oil content. | Premium patio sets, poolside loungers, boat decking. | High-End |
| Cedar | Lightweight and naturally insect-repellent. | Adirondack chairs, planters, and movable benches. | Mid-Range |
| White Oak | Excellent water resistance from its closed-grain structure. | Heavy, durable tables and classic mission-style benches. | Mid-to-High |
Before you can pick the best wood for outdoor furniture, you need to understand why some species handle the elements so well while others rot away in a few seasons. It’s not just about being hard or having a pretty grain. The real secret to a long life outdoors is a wood’s built-in, natural defence system.
This is what separates a future family heirloom from a pile of firewood. The most important factor is how well a wood stands up to the two biggest threats out there: moisture and insects. Some species, like Teak and Cedar, come factory-equipped with their own protective arsenal.
It all comes down to natural oils, resins, and tannins packed deep inside the wood fibres. These compounds are powerful repellents, making the wood taste bad to termites and stopping the fungi and mould that cause decay from ever getting a foothold.
Think of these natural chemicals as a permanent, all-weather coating applied at the cellular level. Teak is legendary for its high oil and silica content, which doesn't just repel water but also makes it incredibly tough. In the same way, the aromatic oils in Cedar—the ones that give it that distinct, pleasant smell—are the very same compounds that keep moths and other bugs away.
White Oak is another classic example. It's loaded with tannins, which are acidic compounds that actively fight off rot and insects. There’s a reason it’s been the top choice for everything from shipbuilding to barrel making for centuries.
These natural protectors are why certain woods can last for decades outdoors with little to no help from us. They offer a core resistance that no surface finish can ever truly match.
A wood's internal chemistry is its first and most important line of defence. While finishes and sealants provide an external shield, the natural oils and tannins within the wood are what truly determine its core ability to withstand the outdoors over the long term.
Beyond rot resistance, the next critical trait is dimensional stability. Wood is hygroscopic, which means it soaks up and releases moisture from the air. This makes it expand and contract. In the unpredictable Canadian climate, that constant movement leads to warping, cracking, and splitting.
The most stable woods are the ones that move the least as humidity changes. A wood's stability is often tied to its grain structure:
Understanding these fundamentals helps you look beyond a simple spec sheet. A wood's Janka hardness rating, for example, tells you how well it resists dents but says nothing about its ability to fight off rot or stay straight through a wet spring. True outdoor performance comes from a combination of these natural defences, giving you a framework to evaluate any species for your next project.
Picking the right wood for outdoor furniture is about more than just looks. It’s a practical decision that hinges on your climate, how much maintenance you’re willing to do, and the project itself. A generic pro-and-con list just doesn't cut it, because the perfect wood for a deck chair on the coast might be total overkill for a sheltered bench in a dry region.
This head-to-head comparison goes beyond the basics to give you a real-world look at the top contenders: Teak, Cedar, White Oak, Acacia, and Ipe. We'll dig into how their unique traits translate into actual performance, helping you make a choice based on context, not just a spec sheet.
There's a reason Teak (Tectona grandis) is considered the gold standard for outdoor wood. Its reputation is built on legendary performance, driven by an incredibly high concentration of natural oils and silica. This internal armour makes it almost impervious to water, stopping the rot and decay that destroys lesser woods in their tracks.
Those same oils also act as a powerful insect repellent, keeping termites and other pests away. It's this one-two punch that makes teak the go-to material for high-end yacht decking and luxury patio furniture built to survive the harshest marine environments. Its dimensional stability is also top-notch, meaning it won’t easily warp or crack when the humidity spikes and drops.
Of course, this level of performance comes with a price tag to match. Teak is easily the most expensive option here, a result of slow growth cycles and massive demand. Aesthetically, it starts as a beautiful golden-honey brown and, if left to its own devices, will gracefully weather to an elegant silver-grey patina.
Cedar, especially Western Red Cedar (Thuja plicata), strikes a fantastic balance between performance, workability, and value. Its defining feature is its light, almost porous structure, which makes it a dream to cut, sand, and assemble—a huge plus for any DIYer.
Like teak, cedar is packed with natural oils and tannins (specifically thujaplicins) that give it impressive resistance to rot and insects, which is also where its distinct, pleasant aroma comes from. While it doesn’t have the brute strength or density of hardwoods like teak or oak, its stability is quite good, and it’s far less prone to splitting than many other softwoods.
This lower density makes it perfect for furniture that you might want to move around, like Adirondack chairs, planters, or lightweight benches. A heavy teak chair is practically a permanent fixture, but a cedar one can be shifted to follow the sun. It's much more affordable than teak but will need more consistent maintenance with a sealer to keep its rich reddish-brown colour and prevent it from weathering too quickly.
White Oak (Quercus alba) is a classic North American hardwood, famous for its strength and historical use in everything from shipbuilding to barrel making. Its secret weapon lies in its cellular structure. The wood's pores, called tyloses, are naturally clogged, making it highly resistant to water getting in.
This closed-grain structure is what gives White Oak its incredible rot resistance. It is exceptionally dense and heavy, giving furniture a substantial feel that’s perfect for large, permanent pieces like dining tables or hefty benches that need to stay put.
The key differentiator for White Oak is its immense structural integrity combined with weather resistance. While Cedar is light and movable, White Oak provides a sense of permanence and stability that is unmatched by most domestic woods.
It's critical to use only White Oak for outdoor projects. Red Oak has an open-grain structure that acts like a sponge, wicking up moisture and rotting out in no time. White Oak is more affordable than teak but typically pricier than cedar, hitting a sweet spot for robust, long-lasting furniture.

Ipe (pronounced ee-pay) is a Brazilian hardwood so ridiculously dense and hard it's often called "ironwood." With a Janka hardness rating of around 3,510 lbf, it’s more than three times harder than White Oak. This incredible density makes it virtually indestructible, providing unparalleled resistance to rot, insects, and even fire.
Originally used for commercial boardwalks, Ipe is an excellent—if challenging—choice for outdoor furniture. It can easily last for over 75 years outdoors with almost no maintenance. Like teak, it weathers to a silvery grey if left untreated, but its original rich, dark brown colour can be maintained with UV-blocking oils.
The difficulty with Ipe is in working with it. Its extreme density chews through saw blades and drill bits, and you absolutely must pre-drill for every screw. It’s also incredibly heavy, making it suitable only for permanent, stationary furniture. While its cost is high, often rivaling teak, its sheer longevity makes it a compelling choice for a "build it once, build it forever" kind of project.
Use this table for a quick side-by-side evaluation of the most popular woods, helping you match the right material to your climate, project, and budget.
| Wood Type | Weather Resistance | Dimensional Stability | Typical Hardness | Required Maintenance | Cost Index | Ideal Use Case |
|---|---|---|---|---|---|---|
| Teak | Exceptional (oils/silica) | Excellent | Medium (1,070 lbf) | Very Low (optional oiling) | $$$$$ | Premium patio sets, poolside loungers, marine applications. |
| Cedar | Very Good (natural oils) | Good | Very Soft (350 lbf) | Moderate (sealing recommended) | $$ | Adirondack chairs, movable benches, planters. |
| White Oak | Excellent (closed grain) | Very Good | Hard (1,360 lbf) | Moderate (sealing needed) | $$$ | Heavy dining tables, sturdy benches, mission-style furniture. |
| Acacia | Good (natural oils) | Moderate | Hard (1,700 lbf) | High (regular oiling essential) | $$ | Budget-friendly full dining sets, accent tables. |
| Ipe | Exceptional (extreme density) | Excellent | Extremely Hard (3,510 lbf) | Very Low (optional oiling) | $$$$ | Permanent benches, heavy-duty tables, commercial use. |
This quick comparison highlights the trade-offs you'll be making. Whether you prioritize low maintenance with Teak or Ipe, value the workability of Cedar, or need the brute strength of White Oak, there’s a perfect wood for your next outdoor build.
Choosing the best wood for your outdoor furniture isn’t a one-size-fits-all deal. The perfect species for a massive dining table is rarely the best choice for a lightweight, movable chair. Context is everything. The secret to building something that lasts is matching the wood's natural properties to your project's specific demands.
This is where you move from general advice to practical application. A wood’s stability, weight, and strength must line up with how the furniture will be used and where it will live. Get this right, and your finished piece will perform exactly as you need it to.
For big, beefy pieces like dining tables or permanent benches, your top concerns are strength and dimensional stability. These projects need a material that can carry a lot of weight and resist warping across a large surface.
Both of these woods have the robust nature required to anchor an outdoor living space, making sure your centrepiece furniture stays solid and true through the changing seasons.
When you’re building chairs, planters, or other items you might want to move around, weight becomes a huge factor. No one wants to lug a heavy oak chair across the patio. For these pieces, you want a lighter structure that’s also easy to work with.
Cedar is the undisputed champ in this category. It’s incredibly lightweight and its soft texture is a joy to cut, sand, and assemble. This workability is a massive advantage for projects with curves and complex angles, like the classic Adirondack chair.
The right wood choice reflects the furniture’s function. A heavy, dense wood like White Oak provides permanence for a dining table, while the lightweight and aromatic nature of Cedar offers portability and comfort for a classic lounger.
This is especially true in Canada’s varied climates. A woodworker in humid Vancouver will prioritize rot resistance above all and likely lean toward Cedar. Meanwhile, someone in arid Alberta might focus more on a wood's ability to resist cracking, favouring an oil-rich species like Teak.
Furniture destined for the splash zone or for use as planters is in a constant battle with moisture. For these high-exposure projects, exceptional water and rot resistance is non-negotiable.
The growing trend of creating functional outdoor spaces has driven major demand for durable, beautiful furniture. In fact, 62% of home buyers now see outdoor living areas as a key factor in their purchasing decisions. You can discover more insights about outdoor furniture market trends to see how consumer preferences are shaping the industry.
The flowchart shows a primary decision point for many woodworkers, guiding them toward premium Teak for high-end projects or versatile Cedar for more budget-conscious builds. To further refine your choice, you can also browse wood options organized by project type to find the perfect match for your specific needs.
Your project isn’t done after the last screw is tightened. Picking the right wood is only half the job; the other half is proper finishing and consistent upkeep. This is where you protect your investment from sun and moisture, ensuring it stays strong and looks great for years to come.
The finish you choose sets the tone for both the furniture's final look and its long-term care routine. Your choice really boils down to two paths: penetrating oils that protect from within, or film finishes that create a tough shell on the surface.
Penetrating oils like Tung, Teak, and boiled linseed oil do exactly what their name suggests—they soak deep into the wood fibres. This process enhances the natural grain and colour, leaving a rich, matte finish that feels like real wood because, well, it is. These oils are a perfect match for dense, naturally oily woods like Teak and Acacia, as they work with the wood to replenish its defences against moisture.
The biggest win for an oil finish is how easy it is to maintain. When the wood starts looking a bit dry or faded—usually once a year—you just clean the surface and wipe on a fresh coat. No peeling, no flaking, and best of all, no need to strip off the old finish.
Film-forming finishes, like spar urethane or exterior varnish, offer a totally different kind of protection. They lay down a durable, almost plastic-like barrier that provides top-tier defence against both water and UV rays. This makes them a great choice for less weather-resistant woods or for furniture that's going to see a lot of wear and tear.
The trade-off, however, is the upkeep. If that protective film gets scratched or breached, moisture can sneak underneath, causing the finish to peel, bubble, and fail. Repairing it isn't a quick touch-up; it often means sanding the entire piece back to bare wood and starting from scratch. For anyone looking to get that application just right, mastering wood finishing techniques is crucial for a flawless, long-lasting result.
For certain dense, resilient woods, there's a third, very appealing option: do almost nothing. Woods like Teak and Ipe are so packed with natural oils and resins that they can be left completely unfinished to fend for themselves.
When left untreated, dense tropical hardwoods will slowly weather from their original vibrant hues to a distinguished, silvery-grey patina. This look is highly sought after and signifies a piece of furniture that is aging gracefully with its environment.
This transformation doesn't harm the wood's structural integrity one bit. The silver-grey colour is purely a surface-level change caused by exposure to sun and rain. This approach is the definition of low-maintenance, requiring nothing more than an occasional scrub with mild soap and water to keep it clean. It's an aesthetic choice that celebrates the wood's natural character as it settles into its surroundings.
No matter which finish you land on, a simple seasonal care routine will dramatically extend the life of your furniture.
A little proactive care ensures the outdoor furniture you worked so hard on remains a source of pride for many seasons.
Even after comparing all the specs, a few practical questions always pop up right when you’re ready to buy lumber. Choosing the best wood for outdoor furniture means getting straight answers on cost, durability, and finishing. Let's tackle those common hang-ups so you can move forward with confidence.
Getting these details right from the start ensures your project begins on solid ground, saving you from costly mistakes or maintenance headaches down the road.
While Teak holds the crown for sheer durability, its premium price is a major roadblock for many. If you're looking for that sweet spot of high performance and genuine value, Acacia and White Oak are your best bets.
Acacia is a dense hardwood with fantastic natural resistance to both rot and insects, and you can often find it for a fraction of Teak's cost. White Oak is another workhorse; its closed-grain structure makes it incredibly resistant to water—a trait proven by its long history in shipbuilding and barrel making. Both are excellent choices for building furniture that lasts without the high-end price tag.
Honestly, using standard, untreated pine for outdoor furniture is a bad idea. It has zero natural resistance to decay or insects and will start to rot surprisingly fast once it's exposed to rain and humidity.
You might see pressure-treated pine sold as a budget-friendly option, which is chemically infused to resist rot, but it often has a greenish tint and isn't the best look for fine furniture. If you absolutely must use an untreated softwood like pine, you’ll need an flawless finishing process with multiple coats of a top-tier exterior varnish just to give it a fighting chance.
Choosing the right wood from the start is far more effective than trying to force an unsuitable wood to do a job it was never meant for. A naturally resistant species will always outperform a weaker wood that relies solely on a surface finish for protection.
This choice really comes down to the look you want and how much maintenance you’re willing to do. You're basically deciding between a natural, "in-the-wood" finish and a durable, "on-the-wood" barrier.
Here’s the breakdown:
The best way to verify a wood's origin is to look for third-party certifications. The Forest Stewardship Council (FSC) is the most recognized global standard, ensuring the wood comes from responsibly managed forests that provide environmental, social, and economic benefits.
In North America, another prominent certification is the Sustainable Forestry Initiative (SFI). Don't be shy about asking your lumber supplier where their wood comes from, especially with tropical hardwoods. A reputable dealer will be transparent about their sourcing and can provide certification details, making sure your project is built with integrity.
