A heck of a challenge to put together!!  To us about 5 solid hours.  We really like the look and sturdiness and overall this has worked out well; but we did have to add a 4" block to each end of the top horizontal to "extend" it as our 70" TV feet/stand/footings were wider.  A bit of a bummer after all this work but once we paint the blocks black you hardly be able to tell.
