When it comes to the large and complex world of furniture, there are two main types: indoor and outdoor. There are some types that are a hybrid of the two, but these are few and far between because of the different processes used to make each kind. You can almost never use your indoor furniture on the outside, but you can typically bring furniture in from the outside and use it without any problems. Remember this when you are considering having an outdoor party, and are thinking about moving some of your chairs and tables outside the house into the garden for more seating space.
If you have some common sense, now would be a great time to use it. It is pretty obvious that some materials that are used on furniture are better for the outdoors than others. The type of furniture is obviously going to factor into this. For the most part, the materials that you pick for the outdoors needs to be sturdy, durable and firm. They need to be able to stand up to a fair amount of moisture, exposure to sunlight and fluctuations in temperature. Outdoor furniture is very strong indeed, so you should make sure you never take any of your softer, more sensitive bits and pieces outside. This means that ALL FABRIC is out of the question unless they are 100% waterproof.
Of course, while some indoor furniture doesn’t last long at all on the outside, others are able to stand the elements for a little while longer before you have to start thinking about taking them back in. A good example of this is anything made of wicker. It isn’t the strongest material in the world, but is sometimes used for outdoor furniture like patio chairs for certain areas of the world. While it can be exposed to the outside every now and then, keeping it out there for longer periods of time can cause it to lose its color, to rot, and to basically fail. Make sure that take it indoors when you are done using it.
If you have wooden furniture, you are going to be in luck. You can easily treat wood to be resistant to almost everything that nature has to throw at it, because it came from the outdoors. All that you need to do is put on a layer of varnish, and you are pretty much sorted out for the most part. You do still have to think about the type of wood and the thickness, but for the most part wood is able to survive better on the outside than most metals.
