Memory foam as bass treatment?

Yes, but like all bass traps, needs to be placed well.

Thanks, guys.  

I did some research after posting (should probably have done that first) and the consensus was that it isn’t too effective.

I have lots of GIK panels but was considering ordering a few more and I have this mattress taking up space so thought I might cut it up.  Have since decided not to and order a few more instead.

@audiodwebe That’s the best way to go. 
I like the GIK devices. Their prices are reasonable?

I really like the GIK products (244 with and without the scatter plate).  I've got 10 in my small room, which I think is 13x14.  

Their prices are reasonable.  It's the shiiping that sucked!
