We bought this set as a Mother's and Father's day gift for my parents.  They LOVE it.  My husband and I put together all four pieces in about an hour.  It is comfortable, sturdy and looks great.  The necessary tools come included but I would recommend a ratcheting screwdriver with a hex key adapter.  This made the assembly a LOT easier. I would not use a power tool because stripping the screws is easy unless you are a professional which we are not.
