These are what I was looking for. The first batch I ordered 2 of them were complexly flat like a pancake and would not open up after 48 hours. I tried to get a partial refund and keep 4 of them but they made you buy 6 new ones as a replacement and then drop the other 6 off that were being returned for 2 being defective.Would recommend these for sound proofing or for anyone that has prostate issues. You can sit on these in your car seat and make it so much softer or use them to pack a laptop computer :)

Quality and price

These are absurdly cheap foam. Several never fully extended, close to half. They do little to nothing for sound reduction in any way. Basically throw a pillow in that area and random fabric being around will do about as much good.Strange strong odor.

I received these foam pads on January 5. The instructions said, "Separate and place for 24~48 hours". It is now January 22, more than 408 hours later (2+ weeks), and not one of the pads has fully expanded. Four of the six pads have expanded with about a 2" edge on one side that is still compressed. The other two have about a 5" swath along one side that remains compressed. As a result, I cannot recommend these.

Better than I expected
