This is just what I wanted.  Liked so well I ordered and have received a second one.  (I think it should be noted that it is not totally stable on carpet but is on wood or linoleum.)  I hope to correct this by putting carpet protectors under the legs.

Delivery was one day late, 'cause I am certain by the weather.  The tracking system notified me so it caused no problem.  I am very well satisfied with the whole purchase for the second time.
