This won't be for everyone but I figured I would share just in case it may help other dog lovers. I purchased this dog hammock for the back seat of my CX-3.
Overall, I would say the product is well made and it fits just about perfectly. It even came with a seat belt leash to keep my puppy in place. The selt belt only works on the two outside seat belt buckles. I will attach some pictures. The only other pre-warning I can think of at the moment is that this does not protect the doors. I haven't figured out an alternative for that just yet, but if you use the leash, you shouldnt have to worry much. There is more pictures and information on the Amazon site. I hope this helps!
