Britax Car Seat Waterproof Liner - Moisture Wicking Fabric + No Slip Grip + Machine Washable + Crash Tested

People, I think it's unfair to expect this to absorb liquids like a diaper and completely protect your car seat on its own. It's waterproof, yes. But theres no absorbent material inside. It will contain poo and pee explodes for a child with diapers on its own, but if ones child is starting potty training, one needs to use this together with diapers at the bottom. A toddler can pee ALOT, and you can't expect this to absorb it all - of course if will seep through. We pad the seat with diapers - just open up 2-3 diapers and put them below this seat liner, on top of the car seat. Those will catch any stray messes and absorb the excess pee. When my son was with diapers, we just had to wash this when pee/poo leaked out of his diapers. Now that's he's in underwear, we only had to throw away the diapers soiled with pee and wash this liner. It works if you get more creative. I don't think there's any other seat that's padded like a diaper to fully absorb any leaks anyway. Yes, it moves. I Tried taping it down so my son can climb up the car seat without this slipping... Kinda works but becareful the tape isn't too sticky and destroys the car seat. It's not perfect, but I don't think there's another seat liner out there that is perfect anyway. Stop complaining and use it to your advantage!

Great waterproof liner, has reduced the level of cleans.

Calidad, ha funcionado bien hasta ahora, estamos en control de esfínteres

Love this product! It saves so much time (and sanity) if there is a diaper leak! We all know how tedious car seat cover removal is. Removal of this is simple, throw it in the wash, air dry and return to seat. I have 3 of them, one for each of two vehicles and a 3rd to have so I’m not without while one is being cleaned. Compatible with Britax Poplar.

It’s a little bit smaller than expected, and slides down when my daughter gets in her seat. The buckle cover isn’t like the images, it barely covers anything. We’ve had no accidents yet but I fear if we did they’d get onto the car seat. I bought this because of fast delivery so I could use it immediately, but I also bought another set and now they’ve arrived I think I’ll change to them because they seem better.
