Very sturdy, well made, and attractive, but light for portability.  I like that it folds also, easy to store away.  That said my dog refused to use it.  She is afraid of her own shadow and has refused other items I have gotten to make it easier for her to get to the bed or the back of an SUV.  Almost sent it back, but while I was thinking about it, my cat made getting to her window hammock MUCH easier....  Took care of that...it stays.  

Pros: Great idea for small or senior pets.  Sturdy, attractive, great buy.
Cons: None.
