I was disappointed in the quality of the product. The predrilled holes for the large bolts were too small and we had to go to the hardware store and buy a $25 bit to enlarge them enough for the bolt to fit in. Fortunately we are hardy but what should have been an hour job turned into a two hour job.  If we had not corrected the mistake ourselves and had returned the product, it would have been another hassle hauling the heavy box to ship back. The manufacturer needs to correct the size of the holes.
