This is a great product! I have a large yellow lab who gets motion sickness while traveling. We just came back from a 14 hour trip to Conn. I ordered this product so I could extend the size of my back seat for him. The device was easy to inflate, about 5 minutes total for assembly. I was able to make my back seat more stable and flat for my dog. He had lots of room to turn around and get comfortable. I placed his large bed in the back and he was able to feel more stable and safe. I order this product from Inthecompanyofdogs.com for $69.95.

Pros: Easy to inflat and fits nicely in the gap

Cons: may be cost prohibited for those on a budget

INFLATABLE PILLOW SEAT EXTENDER SO YOUR DOG CAN SEE OUT. I NEVER HAD A DOG THAT WOULD STAY IN JUST SEAT BUT IF YOU HAVE THAT IS GREAT AND THIS PILLOW WOULD BE VERY HELPFUL.

Pros: THESE PILLOWS WOULD WORK

Cons: NONE
