Wood does not seem as quality, or heavy duty as the picture shows.  My chairs are also much lighter than the picture.  It has a very 'shallow' rocking motion, not a deep rock at all.  I have two of them on my concrete shaded patio and am afraid it will tear up the rocking legs due to the tenderness of the wood. I added a cushion and they do look great on my porch.  The back is high enough to give good back support.
