Almost every wooden swing set sold in Europe is pressure-treated pine. Ours are cedar. That difference is the reason Woodlit exists, so this guide has an obvious bias — but the comparison below is honest about what each material does well, because a €650–3,500 purchase deserves facts rather than slogans.
The quick comparison
| Material | Rot protection | Feel and heat | Ageing | Typical trade-off |
|---|---|---|---|---|
| Cedar | Natural oils — no chemical treatment | Smooth; stays cool in sun | Silvers gracefully; one coat of sealant a year keeps the colour | Costs more upfront |
| Pressure-treated pine | Chemical impregnation | Rougher; prone to splinters with age | Warps and checks as it dries | Cheapest wood option |
| Metal | N/A — rust is the enemy | Dangerously hot in summer sun | Coatings chip, then rust | Thin tube frames flex and walk |
| Plastic | N/A | Comfortable | UV makes it brittle and faded | Low weight limits; outgrown fast |
Why cedar resists rot without chemicals
Cedar heartwood carries natural oils that repel moisture, fungus and insects — the tree's own preservation system. Pine has no such defence, which is why pine playground timber is pressure-treated: forced full of preservative chemicals to survive outdoors. The treatment works, but it is the reason treated pine should never be sanded or burned, and it does nothing to stop the warping and splintering pine is prone to as it seasons.
Cedar is also dimensionally stable — it moves less as moisture changes — which is why a cedar deck stays smooth underhand years after a pine one has grown splinters. And on a July afternoon, cedar is comfortable to touch when a metal frame or slide has become genuinely hot.
What cedar asks of you
Honesty works both ways. Cedar costs more than pine — that is the whole trade. And while it survives untreated, it looks best with minimal care: left alone it weathers to a soft silver-grey; a single coat of transparent sealant each spring keeps the warm tone. Every Woodlit set arrives pre-stained with a water-based finish, so year one is covered. That annual coat also keeps the structural warranty fully active.
How our sets use it
Every Woodlit set is cedar throughout — there is no pine hidden in the framing. On the Family Play range the main beams are 86 × 86 mm, roughly twice the section of a typical garden swing set's framing, which is what lets those structures carry adults and earn EN 1176 certification for public sites. Kids Play sets carry a 5-year warranty on wood, metal and hardware; Family Play carries a limited lifetime warranty.
The questions buyers actually ask
How long does a cedar set last? A well-built cedar play system is a 15-to-20-year fixture with basic care — long enough that the children who open it will be teenagers when it is still standing.
Is pressure-treated pine unsafe? Modern EU-approved treatments are regulated and widely used. Our objection is practical, not alarmist: treated pine splinters, warps and needs re-treating, and we would rather build from a wood that protects itself.
Metal never rots — why not metal? It rusts instead, flexes under enthusiastic swinging unless heavily built, and turns hot enough in summer sun to end play until evening. Wood carries none of those problems.
