Chairs are labeled assembly difficulty as 1 out of 5.  They are however 5+ out of 5.  The pre-measured holes do not line up with the frame of the chair.  They indicate on the instructions that you will only need the allen key supplied and a phillips screwdriver. This is not the case.  The seat cushions are not pre-drilled and you need an electric screw driver to attach to frame. These chairs are difficult to assemble and will take 2 people. The only reason I have not returned them is  it was too much work to put them together.
