Bench is stylish and well constructed.  Took about an hour to put together, although it took a lot of staring at the single page illustration-only instructions to figure out what pieces went where.  Seems sturdy enough after completion.

However, the glide distance is maybe 2-3" at most.  A simple porch swing would serve a better purpose.  Even worse, when gliding back the entire glider tends to want to tip over backwards and the front legs rise up off the surface.  Huge turnoff!  Since I already coated the entire piece with good quality spar varnish, it is too late to return.  Will attempt to screw the front of the glilder directly to the wood deck in order to mke sure it won't rise up and tip backward while gliding.   I guess for only $149.00 you take your chances.
