I have this table too, and want to address the finish. In natural, there is NO finish. Wood is porous, dry wood is very porous. If you don't mind a change in color (test underside first!!!), I recommend what woodworkers from long ago have used, which is tung oil. build up several light coats. Another alternative is to use a good paste wax, but be aware that clear paste wax also eventually yellows. Any sealant of any sort will change the color slightly. We are a family of designers and builders, and my plan for this table is paste wax.
