The trellis fits perfectly in the spot in my yard for which I purchased it.  We will be training a wisteria vine on it and it is lovely.  However, it blew over two days after we placed it in the soil.  We solved this by purchasing anchors which should be sufficient to keep the trellis upright (keeping our fingers crossed!).  The trellis should have been manufactured and packaged with proper anchors for a more sturdy installation.  The instructions suggest concrete installation or the use of rot-resistant 2X2's, but that information should be available in your description of the item.
