Someone put a knock off version in the diono box and returned it. Diono obviously did not check the contents!

This is a fairly thick seat cover. Very sturdy and stylish. Helps prevent wear and tear from small children and car seats.I have a 2024 Sienna and have this on the middle three seats. It fits well.

I have this under both my kids' car seats. I have a two year old, and am expecting baby #2 in 5 short weeks. It was incredibly easy to install this seat cover, and makes me feel much better about any potential snack spillage from my toddler, or spit ups I'm sure my newborn will have in the car.On that note, I wish I could tighten the straps that go around the head rest just a tiny bit more. It almost seems like the cover is slightly too large for my 2017 Honda CR-V, so the middle seat cover folds over itself a tiny bit, and I wish I could tighten the straps to do away with that. Regardless, I'm not trying to protect the back of the seats as much as the bottom, so I don't mind the cover being slightly on the large size.Overall though, it had absolutely NO effect on securing the car seats to the car, which was the most important thing, so I'm very pleased with this purchase!

This is perfect for the back seat of my new car. I brought this so that the kids carseat wouldn't ruin the fabric of my car.

Easy to fit and easily cleaned but just wish they were better fitted, the front covers get a crease down the centre of the seat pad part on mine anyway, doesn’t effect the overall quality because I think they are great but just wish they were a little bit better fitted

I have 2 kids who are both still in car seats. I was looking for a protective cover that was ‘crash tested’ and came across this. I have had this for over a year now on my backseat and it has been awesome. It has protected my cloth seats from EVERYTHING. There are no dents from the car seats either. Most importantly it is very secure and car seats don’t slip around on it. It is fairly easy to clean. The only thing that bothers me sometimes is in the middle, on the back rest part it protrudes a little but it is a big size and I have a Honda Civic. I was cleaning it today and thought I need to make a review for this because it has been amazing and I see myself using this for many years to come!

Thick materials! Base is one piece, backing zips to allow sections to be folded down. Will help save the seat from car seat imprints, any spills and a million crumbs. Will be easy to clean. Seat belts lined up perfectly on 2016 Dodge RAM Rebel. Only complaint - wish it was 10” wider to completely cover the top of the seat.

This fits in my truck perfect. I have a full size 2022 GMC Sierra and it covered the entire back seat. It has plenty of zippers and spaces to allow all the buckles and what not to fit through. Very glad we paid a little extra for quality !!

Fit my company SUV perfectly but some of the mesh pockets are coming apart within a week. Took off a star for durability. I love diono products.

I have a 2022 Subaru WRX compact car. I suppose it is considered a midsize car in today’s market. I was hesitant to purchase this rear seat cover as it is marketed as size XXXL. What does that even mean? Is it only for Chevy Suburbans and Hummer H2’s? My bench seat measures 48” wide and the description of this item states it will cover up to 55” wide. Being that I couldn’t find a Diono cover on Amazon that was XXL or XL, or L, or M, or S, I figured the 6” of extra width could be tucked in or could simply drape over the ends of the rear bench. Well, to my surprise this cover is literally the perfect size. I don’t know how this would cover the seats in the back of a large body on frame SUV but it’s perfect for my WRX. Look at the pictures I attached. There is maybe at most an inch of overhang on each end. Unfortunately I didn’t measure the cover before I installed it to see if the cover itself was 55” wide. The cover is thick and has padding in between the two outer surfaces. There are three pockets along the entire length of the front of the cover for storage. There is a zipper in the centre for 60-40 split benches or for a centre armrest. It appears to be very high quality and robust; like all Diono products. I will be purchasing another cover like this for my other vehicle.

I'm finally at that stage in life where I get overly excited about the perfect car seat protector. This has been my favorite purchase in my entire eight years of parenting. The Diono Ultra Mat XXXL is a game changer for catching all the little kid crumbs and spills. It's on the pricey side, but the quality is completely justifiable and cheaper than a full-detail-cleaning job. I just replaced two single seat protectors that have been in our car for years with my first two kids, as we are surprisingly expecting our third. I fully expect to be able to reduce the ungodly amount of hours spent cleaning boogers, and other mysterious substances from the crevices of my beloved vehicle and reclaim my weekends back with my family.We have a smaller cross-over SUV (Toyota Venza), and I originally thought this item would be too large for our backseat, as most products like this tend to not fit well, but luckily, the XXXL name is a little deceiving; it actually fits PERFECTLY across the entire backseat. It would easily fit larger vehicles as well. The holes for the seatbelts appear to be designed to accommodate almost any vehicle. It's also thicker and more durable than the other brands of seat protectors we have previously owned. If you love having a clean vehicle as much as you love your kids or pets, this is a product you absolutely need in your life. Trust me on this one!

This product is amazing , searched high and low for something to protect my new car back seats and after long time I found this, it's great quality and definitely worth £50. Fits perfectly to my new ford Kuga. Would definitely advise buying one if you have kids that are younger to protect the apolestrey.
