The table is a solid piece and well worth the money.  The main section comes put together and the only assembly is adding the legs and lower shelf.  The assembly is not hard and takes 15 minutes, though it is easiest to finalize if you have another set of hands to hold the shelf as you tighten the screws.  
I did have one issue with the product.  Upon opening the package, I read a warning label on the bottom of the shelf that stated it is known in California that the product contains chemicals that are known to cause birth defects. The main reason I was shocked to read this was my wife is 38 weeks present and there was no mention of this on the website.  I went back to double check and could not find anything on the matter.  Outside of this, the drawer on one of the two tables we bought had come apart and I had to push the staples back together.
Overall, I am very happy with the tables.
