Yep, most furniture is from pine. But a lot of furniture makers use oak for their high end pieces and use extraction tech. to remove the sawdust, so they can guarantee that it is 100% untreated oak, a few of the more savvy ones have discovered that what was a waste product to them is actually a good little income stream for them, especially with the recent increased awareness of the general public about good food isn't that hard to produce yourself!
