I love it!! Its very sturdy on the sides and the inside is a nice 5 inches of padding! It makes a huge difference enabling them to see whats going on around them. 
     As you can see in the 1st two pictures, Lily jumped in while it was still on my living room floor! She insisted on eating her treats in it!!
     Before anyone panics, I was only putting it in the car, not driving anywhere without it, or them, buckled in! Any doubts I had about them liking it have been proven wrong.  We all love it!
     I  highly recommend this for parents of small furbabies!!
