I was hesitant to buy this as it appeared that most of the positive reviews were from people that had not experienced accidents in the seat. I have been potty training my almost three year old for almost a month. We are doing well but still have the occasional mishap. I actually bought this cover for an upcoming trip where (fingers crossed) she would be able to make it over two hours without going potty. The cover arrived tonight and just for kicks I put it in her car seat (Britax Marathon). It fit perfectly. At this point we had somehow managed to not have any accidents in the car. Not even two hours after having the cover on the car seat, it was tested. We had a short outing and upon arriving home, I noticed her jeans were wet. Not feeling confident (after reading the reviews describing this as nothing more than a paper towel) I yelled for my husband to check the car seat as I cleaned my little pee monkey up. He brought in the cover and said that the only pee that got on the actual car seat was a little on the buckle where the cover has a hole (you can see in the product pics it's where the buckle feeds through). We were pleasantly surprised. I will note that my daughter was wearing jeans that probably aided in the absorption. Anyway, the cover is now hanging in our laundry room drying. I am satisfied with the $13 investment!Update- 12/2015- had this car seat cover a couple of months and daughter just threw up all over herself and car seat. This seat protector performed perfectly as we were able to remove it and just clean the straps that harness her in (we were two hours into a three hour trip through winding mountains). She had thrown up all over her pants but nothing got on her actual car seat due to this seat cover. I'm thinking we will keep this seat cover on her car seat even after she is done with potty training just to protect against other things like getting sick or spilling juice, eat.

I recently bought a britax car seat mainly because of this accessory. Car seat safety is important to me and therefore I haven’t used after market seat covers on the other car seats we have that do not have a cover like this made by the seat mfg. When I saw britax made this, it sealed the deal for me on which brand car seat I was going to buy. This cover is amazing and has saved me from having to clean the car seat on many occasions. It absorbs well. Keeps the liquid where it needs to be, fits well around the buckles, and has been leak proof. Worth every penny!

This is the best car seat pad out there! I've used three brands (summer infant, diono, and britax), and this was the favorite hands down. It has a liner on the bottom so it grips to the seat, which is awesome for kids climbing into the car seat themselves because it limits the sliding.The Diono pad would regularly rotate backwards, rendering it useless, when my son climbed into his seat. (It's worth noting that the Diono did well with absorbing liquid, though, as long as it was in place.)As far as functionality goes, it gets five stars! I have two toddlers (both boys), and both of them have "tested" this pad for its absorbency...with both urine and poop. I'll spare you the details, but trust me: it works. Very well.It washes beautifully. It's seen some things, man, but always comes out looking like new! I wash it on cold, and let it air dry-but the times I've accidentally put it in the dryer on a low tumble, it didn't alter the shape or effectiveness.I have three of these Pads and one Diono pad. Two are always in use, and two I keep as backup.These aren't a "I'll die without this!" Item, but for the work it saves in having to clean a convertible car seat, in my opinion, it's absolutely worth the cost.

So I figured I would write this review to help other parents out in their potty training journey. I was hesitant to buy this because I saw some reviews claiming it isn’t waterproof.To clarify, it is waterproof, but depending on the size of pee accident and the clothes your kid is wearing, the moisture can wick along the seams where the belly buckle comes out and then leak to your car seat cover underneath.The first time I used it, my daughter peed and it wicked down her pants legs and under the pad. I had to wash my car seat liner after all. She was only wear pants since we are potty training and the recline on her car seat is fairly upright.After this we decided to put her on cloth trainers just for car rides. The picture I attached shows a pee accident that did not leak/wick. So overall, I think it’s a great product, but it would be nice if they made the more fabric come up around the belly buckle. If your kid is in underwear and still having pee accidents, I wouldn’t expect it to hold up. If your car seat is a bit more reclined, then the gravity might help the pee go more towards the back than the belly buckle.

I bought this for my Britax car seat, which I had bought knowing I’d eventually buy this car seat protector. 99% of these are after market, which means they have NOT been crash tested, especially with each individual seat. This has been, and my toddler finds it comfortable. I will say that the back folds down at times which is annoying. Thankfully she hasn’t had an accident in it yet, but I know we’re protected if/when she does. I 100% recommend this to anyone who has a Britax car seat and is thinking about potty training. I intend to give mine to my nephew when he is ready (they also have the same seat).

This was/is a life saver. Don't have to worry about leakage of blowouts on the car seat anymore. I was previously just lining it with a cloth, until I came across this. I was a little worried that it wouldn't fit in the Maxi Cosi car seat, but it fits just perfectly!!!Perfect material that it doesn't get in the way of the seatbelts and still comfortable for her to fall asleep on right away.

ITEM PERFECT FOR CAR SEAT

From experience with a 2 year old boy this doesn’t seem to work very effectively in that this protector doesn’t keep wetness out of where the clips attach as the waterproofing doesn’t have a big enough margin. However was very effective everywhere else with catching wetness. This might work better for girls. I still needed to wash car seat on the two occasions when accidents have occurred although majority contained with this product. I would not buy this product again as not fit for intended purpose if you have to wash car seat regardless and not just protector.

Son buenos pero no son totalmente a prueba de agua, en varias ocasiones mi hija tuvo accidentes y la silla terminaba mojada y está cubierta empapada, tuve que comprar varios por si acaso ocurrían los accidentes en lo que mi hija controlaba bien sus esfínteres.
