When this arrived, I was a little apprehensive.  It's a box full of lumber!  I put off building it because I thought it would be a pain.  I finally dragged it over to my air conditioner today and put it together and was pleasantly surprised that it only took me 20 minutes to assemble.  This is a no frills build, but it does the job and looks quite good.  I helps to know what you are getting.  It is unfinished cedar, it does have splintery bits at the ends.  The boards simply slide into a grove cut into the post.  All the boards are milled well, they slid into the groves easily, which was my biggest concern when I first opened the box.  There is nothing to keep the slats in place; in theory, if you picked it up, they could fall out the bottom.  In practice, it held together fine while I moved it into place.  And you could always add your own screws, nails, or glue if you foresaw moving it regularly.

All in all, I'm happy with my purchase.
