The hard floor is much easier to keep clean than the soft fabric base and allows more space for our dog.

Seems good quality
Super good quality, perfect for my car and my dog
Looks very high quality with waterproof fabric I haven't put it in the car yet. Fast Shipping
Very sturdy material, very simple to install, very convenient to remove, very easy to clean, also waterproof, it protects my seat very well, and my corgi likes it very much.
A moment ago I received it, a day before I made an import payment for the delivery to take place, it looks good, we have not yet used the case. There were details with the logistics of the parcel for delivery to my home, seller made sure that it was carried out. Thank you seller
So good.
a faulty one was sent originally, but a replacement one was promptly sent
Excellent service fast supply the only thing is that is a bit slippery but will put a mat on it
Great product A little challenge working out how it all goes together, but we all love a challenge But Great product Only issue is that there is no gap for the seat belt buckle to secure into the seat belt clip whilst the other end attaches to the dog collar/harness
Fitted great
Well designed product that fits well and puppies very comfortable . Been a great option for aging girl who finds it more difficult to jump into the rear of SUV
It’s easy to put and east to use. Great product
.
Looks great
I love it all
The middle slot was hard to get the insert into, other than that a great product! my 28kg maremma has enough room to be comfortable!
Best design and quality for this item. Easy to install and saves on much vacumning. Great overall --- Thank you
Great product, fits perfectly and delivered timely
Perfect fit
The solid base fits well between the front and back seats providing extra space….Unlike my partners car where my pup slides off of the back seat and is suspended in a hammock
Very happy with this product
The hard floor is definitely better than the soft ones. It’s difficult to get the seatbelt hooked up. The material could still be a bit less slippery but am happy with the product. I don’t regret buying it.
Sturdy
Ideal
Issues with a faulty product was handled swiftly and a replacement was sent
Much needed and very useful for keeping my car from being damaged by dog nails and covered in fur
Love my dog backseat extender! Very easy to install!!
Our 6 month old Shitzu loves it, plenty of room to move but is normally lying down on a towel just in case of toilet accidents. As she can see us through the net she seems to be calmer but does do a little whimper for a few minutes when we head off in the car then settles herself down. Glad we bought it as later on we will be caravaning with her.
It was perfect for what i wanted
Looks exactly as advertised. Fits in my Toyota corolla without any issues
Excellent, well designed and constructed product - I highly recommend it to all pet lovers who transport their pets in their cars
Great product, well made and fits my back seat well.
Fits well Dog is very comfortable now can lay down instead of sitting on long distances
It’s great
Love it. Heaps better than our last dog seat. Our Border Collie loves it.
It's good that dogs are a lot safer now, and the leather in my car is more protected.
Fits good. My dogs are mire comfy and stable
This dog back seat protector/cover worked really well for a Great Dane. It supported her and protected the car interior. The extra room provided by the base sheets is a great idea. Easy cleaning and looks like a long life product. The Service provided was great.
Ideal for our very large German shepard
