I bought 2 of these, one for each cat.  They both LOVE THEM and lounge in them under a window during the bulk of the day.  So pleased with them and may buy another one for another room.  (My cats needed a little help at first to understand that the hammock is a bit moveable but is very sturdy.  I lifted my cats into it and gently let go so they understood they could actually stand in them.  Cats easily adapted.)
