Well-made and sturdy. Unfortunately there aren’t enough Xs in the XL as it is too narrow for a Ford Transit Custom Double Cab crew bench, meaning that the outer two seats didn’t align properly. Also not suitable for recessed seatbelt sockets, which this covers up and renders inaccessible; it is designed for seatbelt sockets that can be pulled up above the mat. Seatbelt extenders might be an option, but not for me as I sent it back.

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

Always trust well known brand however on this occasion wasn’t happy with how the openings for the iso fix are positioned as they do not align for both rear seat fixings.

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.

At first we loved this because it seemed like a decent quality and had all the nice attributes we typically look for. It is quick and easy to install and we really like the mesh that fits between the front seats so air can get through. However, after about 3 months of use the product tore at the seam. It was not stretched overly tight or even used that much. Nonetheless it is already in the trash because of the huge tear it got.

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.

Easy to install, heavy duty and perfect to protect my seats from the kids carseats

This seat cover is amazing! It is one of the only car seat protecting products that still allows full and easy access to the child car seat anchor points! Complete game changer! I would recommend every parent gets this. It fit in my 2017 Nissan Rogue like it was made for it. The only minor complaint that I have, is due to the location of the seat belt buckles in my vehicle the are more difficult to access but not impossible. Most vehicles with the buckles closer to where the back and bottom of the seat meet won’t have this problem.
Overall a must have for any parent that wants to save their car upholstery! 👍🏼👍🏼

Har en kona electric och skyddet passade utmärkt på baksätet då vi har två barn i åldrarna 2 och 5år så blir det lätt smutsigt och skyddet täcker bra!

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!
