definitely not oak ... it's pine, maybe fir. I'm beginning to think it's one of the "mediterranean" pieces that were popular in the 1960s -70s, as interpreted by a workshop in Mexico or a home craftsman. It looks like it was made of 2x6 and 2x12s. The clue to Mexican origin is the smell of the wood if you sand it - their usuyal pine species has a pungent spicy smell. Not a "labor chair" - those have hand-holds on the side for the woman to grab during labor pains.

I just finished decorating a client's house and she requested a chair and a half for her "reading nook". I personally had never looked for a chair and a half, but the good quality definitely starts in the $2400 range, after looking at the various furniture stores around here. I think you need to watch out for the back pillow seat rest in the above pic to look crumbled and disheveled after awhile. I ended up getting my client a regular stuffed/tailored chair and ottoman for her area for the $2400 instead. I thought it would be more comfortable for her, and also in her situation, the room was too small for the chair and a half.
