Love these but insufficient directions. One star off only for that reason.

Hope this helps future buyers 

1. The leg section with T-bar is for the front (see picture)
2. I had 3 sizes of bolts. Used the longest for the 2 center holes that connect the legs to the base (keep  the shortest bolts for the square frame - see 3 below)
3. The square frame for the legs doesn’t fit at first. Needs a bit of elbow grease to line up the holes (and use the smallest screws here)
