When you’re choosing an outdoor playset, one of the first decisions is the wood it’s built from. The two options you’ll keep running into are cedar and pressure-treated lumber. Cedar resists rot and insects naturally and lasts 20 to 30 years. Pressure-treated pine costs less up front but typically needs replacing in 10 to 15 years. This guide walks through how the two compare on durability, safety, cost, and looks, so you can pick the right wood for your yard and your budget with confidence.
TL;DR: Cedar wins for most families: its natural oils resist rot and insects, and the heartwood is rated “resistant or very resistant” to decay by the USDA Forest Products Laboratory, giving a 20 to 30 year lifespan. Pressure-treated pine is cheaper and strong but lasts 10 to 15 years and relies on chemical preservatives.
Cedar is the go-to choice for premium playsets because it resists rot and insects without any added chemicals. The USDA Forest Products Laboratory rates cedar heartwood as “resistant or very resistant” to decay in its Wood Handbook, the highest natural-durability tier short of tropical hardwoods. That built-in protection is why most quality cedar swing sets carry a 20 to 30 year outdoor lifespan.
Cedar refers to several coniferous trees in the cypress family. The types used for outdoor projects include Western red cedar, Northern white cedar, Eastern white cedar, and yellow cedar. The wood has a reddish-brown hue and an aromatic scent. Cedar contains natural oils, often grouped as thujone, that make it resistant to rot, decay, and insect infestation. That natural durability makes it a strong choice for swing set frames and the cedar playset kits built for years of outdoor use.
Here are the main benefits of using cedar for a playset:
The main drawback is the higher up-front cost compared to pressure-treated pine or fir. Because cedar lasts so long, though, it often delivers better value over the life of the set. The cedar Gorilla playsets we carry run from $1,250 to roughly $4,979, with the popular Outing model anchoring the value end.
Pressure-treated wood is safe for today’s playsets. The arsenic worry that surrounded it ended in December 2003, when manufacturers voluntarily stopped making CCA-treated wood for residential uses including decks and play structures, according to the U.S. Environmental Protection Agency. Modern treated lumber uses copper-based preservatives that are far less toxic, and the USDA Forest Products Laboratory documents these alkaline-copper systems as the standard residential replacement.
Pressure-treated wood is made by forcing preservatives deep into the lumber under high pressure so it resists rot, fungal decay, and insect damage. The chemicals reach all parts of the board, not just the surface.
The wood preservatives approved for residential use today are:
The copper-based formulations make the wood inhospitable to wood-boring pests and microbes. Treated lumber is easy to spot by its greenish tint.
Benefits of pressure-treated pine include:
The trade-offs to weigh:
Pressure-treated lumber was once a genuine safety concern. The modern copper-based formulations have reduced that risk substantially when the set is installed and maintained properly.
Cedar outlasts pressure-treated wood by 2 to 3 times in a typical backyard. Cedar holds up 20 to 30 years thanks to its natural oils, while properly treated pine or fir usually lasts 10 to 15 years before decay sets in. The USDA Forest Products Laboratory durability ratings explain the gap: cedar earns a top natural-durability class, while untreated pine sits at the bottom and relies entirely on its chemical treatment to compete. Here is how the two stack up across the factors that determine how long a set survives.
Cedar’s natural oils act as a built-in fungicide, so even untreated cedar lasts 15 to 30 years outdoors. Pressure-treated wood depends on the copper preservatives forced into it to fight rot-causing fungi. Properly treated pine or fir holds up 10 to 15 years before fungal decay takes hold.
Cedar is naturally unappealing to wood-boring pests like termites and carpenter ants. Its oils make the wood inhospitable and discourage insects from burrowing into the cells. Pressure-treated wood uses copper compounds to do the same job, and well-treated boards are highly resistant to wood-destroying organisms.
The natural waxes and oils in cedar make it relatively water-repellent, and its density limits how much water it absorbs compared with softer pine. Pressure-treated wood resists fungal decay but is not waterproof. Treated boards will gradually warp, crack, and rot if they sit in standing water or constant moisture.
Cedar has good dimensional stability through sun, wind, and rain, and it weathers to a silvery-gray patina over time. Pressure-treated wood is more prone to checking, cracking, cupping, and splintering in weather extremes. The preservatives do nothing to protect against UV breakdown, so a surface finish is still needed.
Cedar should be cleaned, lightly sanded, and re-sealed periodically. A coat of water-repellent finish every 1 to 2 years keeps it protected, and our guide to staining a wooden playset walks through the steps. Pressure-treated wood also needs cleaning and refinishing, with sealant reapplied every 2 to 3 years, plus replacement of warped or damaged boards.
A properly installed and maintained cedar set lasts 20 to 30 years outdoors, which spreads the cost over decades. Most pressure-treated structures last 10 to 15 years before boards start needing replacement, and the higher long-term maintenance should be part of the math.
Pressure-treated pine wins on sticker price, but cedar usually wins on cost per year of use. Cedar runs about 20 to 30% more than pressure-treated for a comparable set, yet it lasts 2 to 3 times as long, so the up-front premium spreads across far more years. Here’s how the two compare on initial price, lifetime cost, and resale.
Pressure-treated pine and fir are the most affordable options for swing set frames. Per linear foot, cedar can run 2 to 3 times the price of basic construction lumber. Even so, cedar still costs less than tropical hardwoods.
A cedar frame’s longer service life spreads the initial expense over many more years, and you may not face full replacement until decades later. Replacing a pressure-treated playset after just 10 to 15 years, plus the repairs along the way, adds up to more over the full lifespan.
Cedar playsets hold their value well and can often resell for 50 to 70% of the original price years later, which offsets some of the higher up-front cost. Resale is one of the factors a playset buying guide weighs alongside durability, sizing, and yard space. Pressure-treated sets have limited resale value because of their shorter lifespan, and lingering safety perceptions can make them harder to sell used.
Here is how cedar and pressure-treated lumber compare across each major factor:
| Factor | Cedar Wood | Pressure Treated |
|---|---|---|
| Durability | Lifespan of 20 to 30 years | Lifespan of 10 to 15 years |
| Appearance | Warm reddish-brown color | Greenish tint from preservatives |
| Safety | Chemical-free play surface | Safe when dried and maintained; modern copper preservatives |
| Cost | Higher up front, lower long-term cost | Cheaper to buy, higher long-term upkeep |
| Weather Resistance | Stands up well to sun, rain, and moisture | Prone to cracking, splintering, and warping |
| Availability | Stocked as Gorilla cedar sets online and at suppliers | Pine and fir common at lumber yards |
| Resale Value | Holds value well if maintained | Limited resale due to shorter lifespan |
Your family’s needs, budget, and yard will decide whether cedar or treated lumber is the better fit. Cedar is the right call for most long-term homeowners who want a low-chemical set that lasts decades. Pressure-treated makes sense on a tight budget or for a shorter stay in the home. If you’re still weighing materials more broadly, our overview of the best wood for outdoor playsets ranks the common species side by side. Keep these factors in mind:
Weigh these factors and you’ll know whether cedar or pressure-treated lumber fits your family’s swing set needs today and for years ahead.
Cedar edges out pressure-treated pine for a backyard playset. It lasts 2 to 3 times longer, resists rot and insects without added chemicals, and gives kids a clean, natural play surface. Pressure-treated wood is a reasonable budget option, and it’s safe today now that the old CCA formulations are gone, but it asks for more maintenance and won’t last as long. Match the wood to how long you’ll stay in the home, how much upkeep you’re up for, and what your budget allows, and the set will deliver years of backyard fun.
Yes. Modern pressure-treated wood uses copper-based preservatives that are far less toxic than the older arsenic-based CCA, which manufacturers stopped making for residential use in December 2003. Let new boards dry fully and keep the set sealed and maintained, and it’s safe for children.
Cedar lasts 20 to 30 years outdoors versus 10 to 15 years for pressure-treated pine, roughly 2 to 3 times longer. Cedar’s natural oils resist rot and insects on their own, while treated wood depends on infused chemicals that lose effectiveness over time.
Pressure-treated is cheaper to buy, usually 20 to 30% less than cedar for a comparable set. Over the full lifespan, though, cedar often costs less per year because it lasts 2 to 3 times longer and needs fewer repairs and replacements.
Yes, but you have to wait. Fresh pressure-treated lumber holds too much moisture to accept a finish, so let it dry for several weeks to a few months until water beads stop forming, then apply an exterior stain or sealer. Cedar, by contrast, takes stain right away.
