Instructions show assembly drawings which are confusing as the table and benches are not pre-drilled or clearly marked for screw attachment. A customer service rep said the company has stopped pre-drilling holes due to the risk of children eating plastic drill cards. When I asked about pre-drilling the holes myself, she said that pre-drilling is not recommended for customers because the hole may be too big and then the screw will not fit properly and then the customer will get stuck on the table. I put it together and it turned out to be a very nice sturdy picnic set, FYI you may have to figure out the assembly yourself.
