Best Car Seat Liners of 2025

"I was initially worried after reading mixed reviews, but I’m so glad we purchased these. Installation is a breeze, the fabric is soft, and they wash beautifully. We’ve had a few accidents, and they’ve contained everything without leaking onto the car seat. The buckle area is a different fabric and not as absorbent, but it hasn’t been a problem for us. Highly recommend for potty training!"

"These car seat covers have been a lifesaver during potty training! They are fully waterproof and protect the seat from accidents, plus they’re machine washable for easy cleaning. The soft material keeps my little one cozy during car rides. I consider this a must-have for parents!"

"I purchased these after my toddler spilled water all over the car seat, and I knew potty training was coming. They are easy to install, high quality, and soft. They catch spills and accidents, making cleanup so much easier. I definitely recommend this product!"

"I hesitated to buy this protector at first, especially since many positive reviews came from users who hadn't experienced any accidents yet. However, after using it during potty training, I was pleasantly surprised. When my daughter had an accident, the cover did its job well. Only a little got on the actual car seat, which was a relief. For just $13, I’m satisfied with this investment!"

"When I purchased my Britax car seat, I mainly did it because of this seat protector. I was concerned about safety and had avoided aftermarket covers, but seeing that Britax made one changed my mind. This cover has been a lifesaver, absorbing spills and keeping everything contained, making clean-ups much easier."

"After a year of using this product, I have mixed feelings depending on my child's gender. For my son, there were a couple of accidents, but they tended to escape the protector. In contrast, my daughter had fewer issues, and the cover worked excellently for her. I still think it’s worth recommending for younger children, although it may not be perfect for boys."

"I find this car seat cover to be a lifesaver during baby blowouts. My baby tends to have them frequently, and this product has saved me from constantly having to wash the car seat cover, which is a hassle. It's very easy to clean; just rinse it off, dry, and reinstall. It might be a little bulkier than I’d like, but it does its job without interfering with the buckles. I would definitely recommend it!"

"I bought this for my potty training toddler, and it fits perfectly in the car seat. While it can get a bit scrunched and shifted when I’m putting him in and out, it’s not a hassle at all. I appreciate how easy it is to install and remove. I feel reassured knowing that if an accident happens, cleanup will be manageable. I’m very happy with this purchase!"

"This product has been fantastic for my son, especially during potty training. It fits snugly in his car seat and doesn’t leak at all, which is a big relief. I love that it’s soft and comfortable, making it perfect for little ones. I was so pleased after receiving it that I immediately ordered another one for family members who help care for him. I would highly recommend this to anyone!"

"I got this cover for potty training. Cleanup is so much easier! Instead of disassembling the car seat, I can simply remove the cover. The material is incredibly soft, and after multiple washes, it has held up well. It’s also perfect for beach days, just shake out the sand. I even bought one as a gift for another mom!"

"As a frugal person, I tried DIY solutions, but they just didn’t work. This cover fits perfectly and is non-slip with extra pockets. I was worried about it being velvet in the summer, but it’s not too thick, and my toddler stayed cool during our road trip. Although a bit pricey, it’s worth the investment!"

"I really like this cover overall. The waterproof bottom is perfect for potty training. However, I wish the pockets were designed to flap inward instead of outward, as my little guy struggles to reach them."

"After a day at the beach, I found that using this pad in my child's car seat made everything easier. It kept the car seat dry and simplified the process of taking off their wet swimsuit."

"I bought this for my potty training toddler and it has been a lifesaver. When accidents happen, it absorbs well. When we get home, I can just toss it in the washer and dryer without any hassle."

"I had high hopes for this product, but when my toddler peed in the seat, it didn't hold as promised. The car seat was still soaked underneath, which was disappointing since I wanted to avoid washing it all."

“I find the Piddle Pad great for protecting the car seat during potty training. I can easily move it from car to car, which is really convenient. I would definitely buy it again!”

“This pad is perfect for my stroller wagon. It's thick and comfy for both infants and toddlers, and I appreciate that it holds a decent amount of liquid. Plus, it's easy to wash, making it ideal for items without removable covers.”

“In our experience with the Piddle Pad, it fits well in our daughter's Diono car seat. It has helped with easy cleaning after she gets car sick, and I’m sure it will be a lifesaver when we begin potty training!”

“I didn’t purchase this until my daughter was 11 months old, and I regret it. She had a blowout in her car seat during her first week, and I wish we’d had this product earlier. It fits various car seats and is super quick to install. It’s soft and really protects the car seat, making the cleanup of poop and bodily fluids a breeze. I highly recommend it!”

“As a school bus driver with a heavy wetter starting potty training, I can’t stress enough how this product has been a game changer. I began with two, and now I’m thinking I need even more. If there’s an accident, I can just swap it out, keeping her dry throughout the day without the hassle of removing the entire car seat liner. It’s 1000% worth it and has never leaked!”

“I really should have gotten this sooner for peace of mind. It helps prevent my car seat from getting messy due to car sickness or spills. Cleaning the seats can be such a hassle, so this product has been incredibly handy!”

"I’m very happy with my purchase. There was some confusion about what was included, but they promptly sent out the missing items. I will definitely buy from them again. A++++!"

"At first, I thought the car seat liner would be too chunky and hot for my baby. However, once I received it, I realized it's actually really light. It feels soft and cottony without making my baby feel hot and muggy in the car seat. Plus, it’s super cute!"

"This infant car seat liner is so soft and fuzzy! I ordered it in gray, making it perfect for both genders. Though it’s not padded, it provides a soft feel for baby. The slits for the safety belts ensure a great fit no matter the car seat. I would give it a definite 5 out of 5!"

“I really love these! They definitely make cleaning the car seat easier when my kiddos have accidents. They are easy to use, although I wish they would stay in place better, but it’s not a big deal.”

“I had high hopes for these based on reviews, especially for my potty training twins. Unfortunately, after their first accident in the van, it went right through to the seat, leaving me very disappointed.”

“These have been a lifesaver for us! With all the traveling and my little one just potty trained, I wanted something to protect the car seat. They’ve worked wonderfully, are super soft, and easy to wash. No complaints so far!”

"This product fits my Uppababy Vista car seat well, but the slits for the straps are about an inch too small. The fabric is soft and lightweight, and I'm hoping it will help keep my black car seat cool."

"I expected this cover to be universal, but it didn't fit either of my car seats properly. The holes for the straps aren't right, so I'm planning to do some cutting and sewing to make it work."

"While I find it too simple for the price, it does keep the seat cleaner and is easy to wash. If it were more affordable, it would make more sense for the quality."
