These look just like the pictures.  They should slide over my couch perfectly.  They have some good weight to them.  The glass is secured by section cups on each corner.  If they are ever tipped, the glass should stay securely on the base.  They are measured in height 19", 21" and 23".

Delivery was quick and there was not any real damage.  Just a few scratches here and there.  It was also very easy to assemble ( just attach the top).

Please excuse the mess in the pictures.  I'm in the process of moving/unpacking and their is foam everywhere from other packages I received.
