My old cats loves this couch!  It elevates just enough for her to get in and out of comfortably and she can see farther across the yard from the patio door.  Oddly, my 18m Grand daughter loves them, too and lays across them 'Mata Hari' style.  The zipper on the cushion rear allows the addition of a warmer, great for the older kitties.  No assembly, thank you.  A big hit all the way around!

Pros: No assembly required
