Teak Adirondack

A large number of woods are used for the manufacture of outdoor furniture.
There are: Alder, Cherry Braziillian, cedar, cypress, mahogany, pine, pressure treated and Shorea.
The timber may be over to Ebay.
btw Teak is a tropical sweet, excellent for indoor furniture, but when exposed to the weather, it will lose its oil content and cracking has occurred and may lose her beauty.

It depends on what the best would be available in cedar or redwood

if I remember correctly from us. woodworking program [one with Norm. in] he said that you should use teak for outdoor furniture if you can afford.

teak or redwood

The wood and the most popular for outdoor use are, in order of cost, teak, redwood, cedar and pressure treated pine. If this is your first project, I would go with PTP because it is reasonable in price, easy to work and lasts longer than cedar in the measurement of time and infestations of insects. Once the wood has dried, after construction, you can paint or stain as you want, even if it does not look too bad left as is.

If Rosewood is available, I suggest you buy rosewood which is durable and high quality. Here, provide furniture rosewood as high quality. Perhaps this will give you a good idea.
