The cats love it!   One kitten and one 3 year old.   My wife and daughter put it together.  There was no complaints about the instructions, material labeling, or ease to build which is remarkable for these two.   Once down we agreed that is it as LARGE as it appears in the pictures.  We bought the light grey and it's perfect.   The fuzzy material seemed a little cheap however once put together we have to admit it's adequate and the cats love it.   It's TALL but sturdy.
