48"X 24"X 2" Egg Crate Foam Panel, Black Sound Proof Foam Panels, Acoustic Foam, Noise Cancelling Foam Studio Foam Panel, Sound Panels Noise Reducing For Walls（1 PCS）

I purchased these for bedding for our newborn frenchies. Works great and easy to use. You’re able to cut out different sizings of your liking. Worth the money in my eyes since it’s been used several times and it’s been a year. Still in good condition.

Worked perfectly to line our gun cabinet base (I double layered it).

I read several reviews that spoke about this not expanding to the size listed (24 x 48") and that it was a hassle to get it to expand because of the water, but I went ahead and purchased it because of the price. I am happy I did. Within an hour, the foam had mostly expanded to full-size without doing anything but leaving it out. I didn't add water as the instructions mentioned. By the next day, it had expanded to the full 24 x 48 inches. I recommend just leaving it out and not adding water. I will definitely purchase again if needed.

Perfect thickness for the car seat. Comfortable and easy to cut to size.

Excellent sound barrier
