The instructions were fairly straightforward.  A couple of the pre-drilled holes were not lined up accurately. One big problem was that when we attached the lid for the bench the spring hinges pulled/stripped the screw anchors right out of the wood in the back side of the bench.  We had to improvise and buy some longer bolts with washers and nuts to securely attach the bench lid.  Additionally, one of the flat hinges was not installed straight so the bench lid scrapes and sticks on one corner.
