If you ask owners of wooden swing sets what the best wood is, you'll get a variety of different answers. There are those who love their pine set, others who will tell you cedar is the best, and still others will say nothing beats a redwood swing set. The final decision is up to you, but there are several reasons that make redwood your best possible choice.

In order to fully understand the qualities that make redwood the best choice for your swing set, you need to know a little more about the wood itself. Not all redwood is the same and it's important you know exactly what kind you're paying for.

Redwood has a unique pinkish-red color which turns to gray as it ages. There are several grades of redwood, but one of the most commonly used grades for outdoor construction is called Con-Heart. The 'con' stands for construction grade and the 'heart' refers to the fact that it comes from the inner part of the tree, or the heart of the tree.

The natural resistance to rotting and insects only exists in the wood from the heart of the tree. The outermost wood requires staining every year, due to the lack of natural defenses against decay. Con-Heart wood needs no maintenance and if the company you're buying from tells you the swing set will need to be stained annually, you'll know it isn't the heart of the redwood.

Something to be aware of is the presence of any white wood in the swing set you're considering. This is sapwood and has no resistance at all to insects or decay. If you see sapwood, you're not getting Con-Heart wood, because heartwood doesn't have any sapwood. An advantage to wood from the heart of the tree is that its resistance goes throughout the wood so that exposed parts that have been sawed or nailed are just as safe from bugs and diseases.

All woods have a natural response to moisture, and even redwood will swell a bit when it gets wet and shrink slightly if it gets very dry, but it does so to a much lesser degree than other woods. Known for its stability, redwood is able to hold its shape with far fewer incidences of cracks, splits, or warped boards or beams.

When you're investing in a wooden swing set, durability is an important consideration. Because of its ability to fend off decay and bugs, a redwood swing set will still be in great shape and will look better than one built with a different wood, even 20 years down the road.

If you're going to pay a premium price for a premium wood like redwood, be sure you're getting what you're paying for. Companies have been known to use a combination of woods like redwood and red cedar, or Chinese Fir and still advertise it as redwood. Do your homework and know what you're actually paying for. Ask questions and read the fine print before you sign anything.

For the ultimate benefits of redwood, find out if Con-Heart grade redwood was used for all pieces of the swing set. This way you're assured of getting all the natural protection redwood has to offer, not just in the beams and larger pieces, but throughout the entire swing set.
