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）

Used for the recliner and sofas for my grandparents. They are comfy.

Works great

I use this for my pond prefilter. It does an outstanding job of polishing the water. I always had particles floating in my pond water when using just the expensive pressure filter. I change the foam filter every few days, wash, and reinstall. Now my pond stays crystal clear. ;)

I purchased this pad for someone else who is extremely thin and finds sitting for long periods of time, even in a recliner uncomfortable and unpleasant. The pad has been very helpful in easing his discomfort.

Expanded just fine within a few hours of removing from the package.

I would buy again

We are using this to cancel out the background noise. So far its done a good job

These really helped to remove the secondary echo sounds in my recordings. I used the stickers they provided to hang them and they worked well. These two large sections cover a corner mic set up very well. The foam itself feels rather durable and somewhat firm. Very happy with it.
