I would totally give this a zero as the directions make it difficult to figure out what goes where.  was so frustrated then got to the top and cant for the life of me figure it out.  its very cheaply made for what I paid.  so im wondering do I take it apart and ship it back?  Plus I didn't realize the top only holds 15 lbs.  so basically my two cats on it will be overloaded...and bottom 10 pounds.  this table sucks!!
