This shelving unit was fairly easy to put together.  It requires a mallet, but I didnt have one so I used another heavy tool with a towel wrapped around it.  Two people is ideal, but I was able to do it alone.  

The unit is well built and very sturdy.  I opted for no wheels because it holds more weight that way.  The depth of the shelves are great for large storage bins, and just fits more items either way.  Overall a good choice for garages or anywhere you would need storage.
