Best Wood for a Garden Bench: 7 Woods Compared (2026)
Teak is the safest wood for a garden bench — 1,070 lbf Janka hardness, rated “very durable” for decay resistance by The Wood Database, and a 50+ year outdoor lifespan without sealing. But it isn’t the only “very durable” option: black locust carries the same decay-resistance rating at roughly a fifth of teak’s per-board-foot price, and it’s missing from almost every “teak or cedar” list on the web. Below are 7 species compared by Janka hardness, real decay-resistance class, weathering behavior and current price per board foot, so you can pick by what actually holds up outdoors — not just what’s popular.
This guide covers benches specifically — a sitting surface exposed to sun, rain and skin contact, not a raised bed in contact with soil. If you’re building a planter instead, our best wood for garden boxes guide compares the same species by food safety and soil-contact durability rather than sitting comfort and weathering.
7 Garden Bench Woods Compared
Every number below comes from a primary source gathered this session — The Wood Database for hardness and decay ratings, and live 2026 retailer price lists for cost per board foot. Where a retailer prices lumber by the linear foot or square foot instead of the board foot, the board-foot figure is computed and the formula is disclosed in the source notes under the table.
| Species | Janka Hardness | Decay/Rot Resistance | Weathers Unsealed | Typical Bench Lifespan (Sealed) | Price / Board Foot (2026) | Verdict |
|---|---|---|---|---|---|---|
| Teak | 1,070 lbf | Very durable — “gold standard” | Silvery-gray patina, stable, no oil needed to survive | 50+ years | $20–$40/bf1 | #1 Best Overall |
| Ipe (Brazilian Walnut) | 3,490 lbf | Very durable, excellent insect resistance | Grays evenly, resists splitting/checking bare | 25+ years | ~$22/bf2 | Best for Rain-Heavy & Coastal Climates |
| Black Locust | 1,700 lbf | Very durable — same class as teak | Darkens to russet-brown; exclude sapwood | 20–30+ years | $5–$8/bf3 | Best Rot Resistance for the Price |
| White Oak | 1,350 lbf | Very durable — tyloses block moisture | Ages to silver-gray, benefits from UV finish | 15–20 years | $7.50–$10/bf4 | Best Domestic Hardwood |
| Western Red Cedar | 350 lbf | Durable to very durable, mixed insect resistance | Silver-gray patina; very soft, dents/scratches easily | 10–15 years | ~$7–$9/bf5 | Best for DIY Builders |
| Coast Redwood | 450–480 lbf | Moderately to very durable (old-growth stronger) | Minimal shrinkage/movement, takes stain evenly | 12–18 years | $6.50–$12.50/bf6 | Best for Dimensional Stability |
| Pressure-Treated Southern Yellow Pine | 690 lbf (untreated) | Non-durable to perishable naturally — treatment compensates | Checks/splinters if finish lapses | 10–15 years | ~$0.40/bf7 | Best Budget Wood |

What It Actually Costs to Build the Bench
A simple slatted 4-foot garden bench uses roughly 15 board feet of lumber. Holding that quantity constant across every species — plus a pound of exterior stainless screws and a species-appropriate sealant, both live-priced via Amazon — shows how wide the real cost gap actually is between the budget route and the no-compromise route.
| Species | 15 Board Feet | + Stainless Screws | + Sealant | Total to Start |
|---|---|---|---|---|
| Pressure-Treated Pine | $6.00 | $15.99 | $19.94 | $41.93 |
| Black Locust | $97.50 | $15.99 | $28.58 | $142.07 |
| Western Red Cedar | $120.00 | $15.99 | $28.58 | $164.57 |
| White Oak | $131.25 | $15.99 | $28.58 | $175.82 |
| Coast Redwood | $142.50 | $15.99 | $28.58 | $187.07 |
| Ipe | $330.00 | $15.99 | $28.58 (optional) | $374.57 |
| Teak | $375.00 | $15.99 | $41.99 | $432.98 |
Screws: Wensilon #8 1-1/4″ 304 stainless deck screws, 1 lb, $15.99. Sealant (hardwoods/softwoods): Varathane Ultimate Spar Urethane, quart, $28.58. Sealant (teak): TotalBoat Danish Teak Sealer, quart, $41.99. Sealant (budget pine): Thompson’s WaterSeal Clear Wood Sealer, 1 gallon, $19.94. All prices live-verified via the Amazon Creators API, August 2026. Ipe’s natural oil content means many builders skip sealant entirely; it’s listed as optional.
The 7 Best Woods for a Garden Bench
1. Teak — #1 Best Overall
Teak earns its reputation honestly. The Wood Database calls it “the gold standard for decay resistance,” and that’s not marketing — its heartwood contains natural oils and silica that repel moisture and insects without any finish at all. Left completely bare, a teak bench weathers to a silvery-gray patina and keeps functioning structurally for 50+ years.
Specs: 1,070 lbf Janka hardness · very durable decay rating · $20–$40/bf for exterior/rustic grade · no sealing required to survive outdoors.
Who it’s for: anyone who wants to build once and stop thinking about it. Main drawback: the price. At $375+ for just the lumber on a 15-board-foot bench, teak is the most expensive mainstream option here by a wide margin, and premium old-growth boards can run $80–150+/bf. For a full price-by-grade breakdown, see our teak wood cost guide. Most retail “teak” lumber sold in the US today is plantation-grown from Indonesia or Latin America rather than old-growth Burmese stock — plantation teak is still genuinely durable, but it’s worth asking a supplier directly which you’re buying, since the two are priced very differently.
2. Ipe (Brazilian Walnut) — Best for Rain-Heavy & Coastal Climates
Ipe is the hardest wood on this list by a wide margin — 3,490 lbf, more than three times teak’s hardness — and it backs that up outdoors. Ipe decking installed at New York City’s Coney Island boardwalk reportedly lasted around 25 years under heavy foot traffic and full weather exposure before replacement. That’s not a lab claim; it’s a real-world deployment at a scale most lumber never sees.
Specs: 3,490 lbf Janka hardness · very durable, excellent insect resistance · ~$22/bf (derived from decking pricing) · resists checking and splitting even unsealed.
Who it’s for: humid, coastal, or high-rainfall regions where softer hardwoods struggle. Main drawback: ipe’s extreme density makes it genuinely hard to work with standard woodworking tools — expect to pre-drill every screw hole, dull standard blades faster, and possibly need carbide-tipped bits. A 2024 CITES Appendix II listing is also tightening supply and pushing prices up. Ipe is dense enough to sink in water, which is a useful practical check if you’re ever unsure whether a board is genuine ipe or a cheaper look-alike species sold under the same name.
3. Black Locust — Best Rot Resistance for the Price
This is the pick almost every “best wood for garden bench” list skips — and it shouldn’t. The Wood Database rates black locust’s decay resistance as “very durable,” the same class as teak, and its heartwood contains fungal-inhibiting compounds that let it serve as fence posts for decades with zero surface treatment. At $5–$8/bf, that durability class costs roughly a fifth to a quarter of what teak charges for the same rating.
Specs: 1,700 lbf Janka hardness (harder than white oak) · very durable decay rating · $5–$8/bf · darkens to a russet-brown patina with age and sun exposure.
Who it’s for: anyone who wants teak-tier rot resistance without teak-tier cost, and doesn’t mind sourcing from a domestic/regional sawyer rather than a big-box store. Main drawback: the sapwood (the lighter outer rings) rots quickly if it’s not cut away — insist on heartwood-only boards, and expect to hunt harder for a supplier than you would for cedar or pine. Historical use backs up the durability claim well beyond marketing copy: black locust fence posts are a documented case of the inner heartwood staying structurally sound for decades in direct ground contact, a harsher exposure than a bench ever sees, while only the untreated sapwood at the surface degraded.
4. White Oak — Best Domestic Hardwood
White oak has been the boatbuilder’s choice for centuries for one specific reason: tyloses. These are structures inside the wood’s pores that physically block water from wicking into the grain, which is why white oak is rated “very durable” for decay resistance even though it’s a domestic, widely available species — no importing required.
Specs: 1,350 lbf Janka hardness · very durable decay rating · $7.50–$10/bf · ages to a silver-gray without finish, though UV-protective sealant slows color change.
Who it’s for: buyers who want a genuinely durable hardwood from a US supplier rather than an imported tropical species. Main drawback: demand from the bourbon and boatbuilding industries has been pushing white oak prices up faster than most domestic species, and quartersawn boards carry a real premium. Don’t substitute red oak to save money — red oak’s pores lack the tyloses that give white oak its water resistance, so despite looking similar on the shelf, red oak performs noticeably worse outdoors and isn’t a like-for-like swap.
5. Western Red Cedar — Best for DIY Builders
Cedar’s Janka hardness is just 350 lbf — by far the softest wood on this list — and that’s exactly why it’s the easiest to build with. It cuts, drills, and sands with hand tools far more readily than any hardwood here, and at roughly a quarter the weight of white oak, a finished bench is genuinely easy to move around the yard.
Specs: 350 lbf Janka hardness · durable to very durable decay rating, mixed insect resistance · ~$7–$9/bf for select/clear grade (construction-grade knotty runs $2–5/bf) · weathers to silver-gray.
Who it’s for: first-time builders and anyone prioritizing ease of construction over maximum lifespan. Main drawback: that same softness means cedar dents and scratches easily in daily use, and iron-based fasteners can leave dark staining in damp conditions — stick to the stainless screws in the cost table above. Full pricing detail in our cedar wood cost guide.
6. Coast Redwood — Best for Dimensional Stability
Redwood moves less with humidity and temperature swings than almost any other species on this list — its volumetric shrinkage is only about 6.9%, which in practice means fewer sticking joints, less seasonal racking, and a bench that stays square longer. Old-growth stock outperforms second-growth for decay resistance, but both take stain and sealant evenly.
Specs: 450–480 lbf Janka hardness · moderately to very durable decay rating · $6.50–$12.50/bf for Clear All Heart grade · minimal shrinkage and warping.
Who it’s for: West Coast buyers with local supply access and anyone who’s had a bench warp or rack out of square before. Main drawback: coast redwood is listed as endangered on the IUCN Red List after roughly a 50% population decline over three generations — worth factoring into a sustainability-conscious buying decision, and worth confirming FSC or reclaimed sourcing where possible. Reclaimed redwood in particular is worth actively seeking out here: because so much old-growth redwood was harvested decades ago and is now being salvaged from old structures, reclaimed stock can actually offer better decay resistance than new second-growth lumber, at a comparable or lower price.
7. Pressure-Treated Southern Yellow Pine — Best Budget Wood
Untreated, southern yellow pine (commonly loblolly pine) is rated only “moderate to low” for decay resistance — it’s not naturally suited to outdoor exposure at all. Pressure treatment with preservatives is what makes it viable outdoors, which is also why it’s sold almost exclusively as treated lumber for exterior use. At roughly $0.40/bf, it’s not close to competitive with any other species on this list on price.
Specs: 690 lbf Janka hardness (untreated base) · naturally non-durable, treatment-dependent · ~$0.40/bf · widely available at any lumberyard or home center.
Who it’s for: tight budgets and benches you’re prepared to reseal on a strict schedule. Main drawback: pine checks, splinters, and cups faster than every other option here if the sealant lapses — on a seating surface, splintering is a real concern for bare skin, not just an appearance issue. Check the treatment rating before buying: lumber rated for “ground contact” carries a higher preservative retention than “above ground” boards, and while a bench doesn’t need ground-contact-rated wood for the seat itself, any legs set directly into soil should use it.
Where to Actually Buy Each Species
Availability varies a lot more by species than most guides let on — some of these boards are at any home center, others need a phone call to a specialty yard. Here’s what to actually expect when you go looking.
- Teak: exotic-hardwood specialists (Advantage Lumber, Bell Forest Products) carry it as decking/board stock; big-box home centers generally don’t. Expect to order online or from a marine-supply yard.
- Ipe: sold almost exclusively as decking through specialty exotic-lumber dealers (Buy Ipe Direct, Advantage Lumber). Confirm current CITES paperwork with the supplier given the 2024 Appendix II listing.
- Black Locust: the hardest species on this list to source nationally — it’s regional, sold by small sawmills and fence-post suppliers in its native eastern-US range (Kingdom Forestry Products, Midwest Black Locust) rather than carried as a standard SKU. Worth a call before assuming it’s local.
- White Oak: genuinely widely available domestically through hardwood dealers and larger lumberyards; The Wood Yard’s 2026 list above is a representative example of typical retail pricing.
- Western Red Cedar: the most universally stocked species here — any home center or lumberyard carries construction-grade cedar, though select/clear grades usually mean a specialty yard.
- Coast Redwood: readily available on the West Coast, meaningfully harder and pricier to source east of the Rockies due to freight. Buffalo Lumber and similar Pacific Coast yards quote by phone rather than posting fixed prices.
- Pressure-Treated Pine: stocked at every home center and lumberyard in the country — the one species on this list you can walk in and buy same-day, in any dimension, no ordering required.
How We Picked These Woods
This is a Tier C, compared-not-tested guide: nobody on our team built and weathered seven benches for this article, and we’re not going to pretend otherwise. What we did instead: pulled Janka hardness and decay-resistance ratings for each species directly from The Wood Database — the standard reference source for North American and imported lumber properties — and cross-checked current per-board-foot pricing against live 2026 retailer price lists (The Wood Yard, Advantage Lumber, Buy Ipe Direct, Kingdom Forestry Products) rather than copying numbers from other roundups.
Where a species is conventionally priced by the linear foot or square foot instead of the board foot (ipe decking, cedar dimensional lumber), we computed a board-foot equivalent and showed the formula in the source notes under the main table rather than presenting an apples-to-oranges number as directly comparable. Where a number couldn’t be confirmed from a primary source this session, it’s left out rather than estimated — there are no invented specs or star ratings anywhere in this article.
The screws and sealants in the cost table above are real, live-priced Amazon listings, not category averages — each one was verified with a returned buy-box price via the Amazon Creators API on the day this guide was compiled, and the ASIN links go straight to the listing. None of the three competitor guides we read while researching this piece (a bench-specific buyer’s guide, a rustic-furniture supplier’s wood breakdown, and a general contractor’s durability guide) publish a comparable spec table, a per-board-foot price, or any structured data at all — which is the gap this guide is built to fill.
What to Consider When Choosing Wood for a Garden Bench
Decay and Rot Resistance
This is the single biggest factor for an outdoor bench, and it’s a property of the heartwood, not the whole tree — sapwood on nearly every species rots faster regardless of the species’ overall rating. The Wood Database’s four-tier scale (perishable, non-durable, moderately durable, durable, very durable) is the closest thing to a standardized reference in this space, and it’s what every row in the table above is drawn from. That rating describes resistance to fungal decay specifically, not insect resistance or UV stability — a species can be “very durable” against rot and still need a UV-blocking finish to hold its color, or vice versa, so it’s worth checking a species against all three properties rather than assuming one rating covers everything.
Janka Hardness and Sit-Comfort
Janka hardness measures resistance to denting — relevant on a bench because heels, tool drops, and dragged furniture all leave marks on soft wood. Cedar’s 350 lbf rating means it dents under normal use; ipe’s 3,490 lbf means it essentially won’t. Harder isn’t automatically better for comfort, though — very hard woods transmit less give when you sit down, which is a real (if minor) tradeoff some builders round the seat edges to offset.
Weathering and UV Exposure
Every wood species grays with UV exposure eventually — it’s a surface effect from lignin breakdown, not a sign of structural failure. The species that “weather well” are the ones that gray evenly without checking (splitting) or raising a rough, splintery surface. Teak, ipe and black locust weather cleanly; softer, less naturally durable woods like untreated pine are far more prone to visible splitting if left unsealed.
Splinter Risk on a Sitting Surface
Unlike a garden box or a fence, a bench is in direct, sustained contact with skin and clothing. Softwoods that check and splinter under UV/moisture cycling — pine especially — are a genuine comfort and safety issue on a seat in a way they aren’t on a planter box wall. This is the single biggest practical difference between choosing wood for a bench versus choosing it for a raised bed.
Price per Board Foot
Board-foot pricing is the only way to compare species fairly, since boards ship in wildly different widths, thicknesses and grades. Always confirm whether a quoted price is per board foot, linear foot, or square foot before comparing two suppliers — mixing units is the single most common lumber-pricing mistake, and it’s why several rows in the table above show a “derived” conversion with the formula disclosed. As a reminder, one board foot equals a piece of lumber 12 inches long, 12 inches wide, and 1 inch thick (144 cubic inches); for any board, the formula is (thickness in inches × width in inches × length in feet) ÷ 12. Grade matters as much as species — within any single species, a jump from construction-grade to clear/select grade can double the per-board-foot price without changing the wood’s decay resistance at all, only its appearance.
Sustainability and Certification
Not every durable species is an unlimited resource. Coast redwood is IUCN-listed as endangered after major population decline, and ipe’s 2024 CITES Appendix II listing signals tightening international trade controls. FSC (Forest Stewardship Council) or PEFC certification is available for many of these species and is worth asking about specifically — it doesn’t change the wood’s physical properties, but it does change where the lumber actually came from. Domestic species carry a real, often-overlooked sustainability advantage that has nothing to do with certification: white oak, black locust, and southern yellow pine all ship far shorter distances than teak or ipe, which cuts transportation emissions out of the equation entirely regardless of how the forest itself is managed.
Fastener Compatibility
Cedar and oak both react with plain steel fasteners in damp conditions, leaving dark stains around every screw head within a season. Stainless steel (304 or better) avoids this entirely and is worth the small extra cost on every species in this guide, not just the premium ones.
Maintenance Schedule
Teak and black locust can genuinely be left unsealed and still hit their multi-decade lifespan estimates. Everything else in this guide needs a real reseal schedule — annually for pine, every 1–2 years for cedar and redwood — to hit the “sealed” lifespan figures in the main table. Skipping that schedule doesn’t just cost appearance; it materially shortens the wood’s functional life.
How to Seal and Maintain a Wood Garden Bench
- Clean the bench with a soft brush and mild soap and water, then rinse thoroughly and let it dry for 24–48 hours before applying any product.
- Lightly sand any weathered, gray, or rough patches with 220-grit sandpaper, working with the grain, then wipe away all dust.
- Choose a sealant matched to the species: a penetrating oil (like teak sealer) for oil-rich hardwoods such as teak, or a film-forming spar urethane for cedar, oak, redwood and pine, which don’t have teak’s natural oil content.
- Apply in thin coats with the grain, following the product’s stated coverage rate — thick coats trap moisture underneath instead of shedding it.
- Let the sealant cure fully per the label before sitting on or covering the bench — most spar urethanes need 24–48 hours between coats and up to a week before heavy use.
- Reapply on a species-appropriate schedule: teak and black locust are optional most years, cedar and redwood benefit from a reseal every 1–2 years, and pine should be resealed annually to avoid the checking and splintering described above.

Frequently Asked Questions
What is the best wood for a garden bench?
Teak is the best overall choice — 1,070 lbf Janka hardness, a “very durable” decay-resistance rating from The Wood Database, and a 50+ year lifespan outdoors without any sealing. Black locust matches teak’s decay-resistance class at roughly a fifth of the price if budget matters more than brand recognition.
Is pine good for an outdoor bench seat?
Only if it’s pressure-treated, and only with a strict resealing schedule. Untreated southern yellow pine is rated “moderate to low” for decay resistance and will rot within a few years outdoors. Even pressure-treated pine checks and splinters faster than every other species in this guide if the sealant isn’t reapplied roughly once a year — a real concern on a seating surface.
How long does a teak garden bench last outside?
50 years or more, based on teak’s natural oil and silica content and its “very durable” decay-resistance rating. It can be left completely unsealed and will simply weather to a silvery-gray patina without losing structural integrity.
Do you need to seal a wood garden bench every year?
It depends on the species. Teak and black locust can go without sealing most years and still hit their multi-decade lifespan figures. Pressure-treated pine should be resealed roughly annually, and cedar or redwood benefit from a reseal every 1–2 years to avoid premature checking and graying.
Is cedar or teak better for a garden bench?
Teak lasts longer and needs less maintenance — 50+ years unsealed versus cedar’s 10–15 years even with regular sealing. Cedar is far easier to cut and build with (350 lbf Janka hardness versus teak’s 1,070 lbf) and costs a fraction as much per board foot, which is why it remains the more common DIY choice despite the shorter lifespan.
What is the cheapest wood that still works for an outdoor bench?
Pressure-treated southern yellow pine, at roughly $0.40 per board foot — a fraction of every hardwood in this guide. It requires the strictest maintenance schedule of any option here to avoid splintering on the seating surface, so factor annual resealing into the real cost, not just the lumber price.
Can you use pressure-treated pine for a garden bench seat?
Yes, and it’s the most common budget choice — but sand it smooth and keep it sealed. Pressure treatment addresses rot and insect resistance, not the checking and splintering that untreated softwood surfaces develop under UV and moisture cycling, which matters more on a seat than on a fence board.
Final Thoughts
Teak remains the safe #1 pick for a garden bench — the numbers back up the reputation. But the one fact worth carrying away from this guide is that teak isn’t the only “very durable” wood on the market: black locust carries the same Wood Database decay-resistance rating at roughly a fifth of teak’s per-board-foot price, and it’s absent from nearly every competing roundup. Whichever species you choose, match the sealant to the wood and hold to the maintenance schedule — that’s what actually determines whether your bench hits its 10-year estimate or its 50-year one.
