I read many reviews before purchasing this table.  Most of them said you needed 2 people to assemble this table.  NO YOU DON'T.  The reviews scared me and I asked my son, whom is an engineer, to assemble it for me.

When you take it out of the box, you will see 2 metal rings.  Place 1 on top of the other, & you will see 1 is larger than the other.  The same for the glass.  If I remember correctly, the small ring & glass are for the bottom, the larger ring & glass are for the top.  The instructions really should state this.
