Aggrivated!! After having this box sit in the corner for weeks while we moved in, I finally went to put it together...the bolts really look all the same size..even though the direction sheet shows significant difference. I carefully looked at them as they arrived all in the same bag. Not being able to see any differences I started putting it together...assembly is easy but 2 of the bolts popped right thru the top...Looking again, there is a VERY slight difference but still difficult to notice and I have put together A LOT of furniture in my life!! Very disappointed in this product! Now I have a table that needs a new top already.
