Stone Age furniture
Before trees were chopped and wood was shaped for furniture and other stuff, men would work with stones (that is, of course, why they call it the Stone Age). This table is made out of stone (though glass is not very stone-age-y). This is something the Flintstones would probably have in their house.
We could get a little peek into the Stone Age watching The Flintstones; although we know not everything was actually like how it was shown (for example, men didn’t hang out with dinosaurs), the concept was entirely on point. I wonder what they used to carve rocks back then.
