## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice quality
  

*by D***S on Reviewed in the United States on May 6, 2024*

I just received this today.  It took about 5 minutes to install.  It appears to be good quality with metal buckles and reinforced stitching.  It fits nicely in my volvo xc90.  I travel long distances and felt badly about having my puppy crated for so long in the car.  He is not yet fully house broken.  This is perfect for him.  It is Waterproof in case he has an accident and protects most of the car from chewing.  I am thinking about putting some velcro on the passenger door to make it better form filling, and maybe a screen for that window so I  can roll it down.  Pup will be about 80 lb full grown, so we will see how it holds up.

    Best One Out There
  

*by A***R on Reviewed in the United States on August 14, 2024*

I've gone through two other mats and they didn't last and would sag as well, making the dog hair fall everywhere.  I love that the bottom of this mat is firm/sturdy and stays in place.  Love the side panels too.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works perfectly
  

*by F***M on Reviewed in the United States on August 17, 2024*

It is easy to put in and take out and keeps the backseat very clean.  Our dog loves the extra space and stability!
