I have used Dream Green several times, and enjoyed several things about it. First is how it drapes - it handles really well when your quilting it (I've quilted it both on my DSM and on my LA - no problems at all), and I like how smooth it lies across my bed. And since I said something about the smoothness, as others have said, there is minimal "crinkle" - and I think that was mostly due to the cotton fabric, and not the batting. If that "smoothness" is what you're looking for, Dream Green is terrific. And finally, I really like the idea that using this product removes at least a LITTLE bit of trash from the landfill.
And as far as the comment about the product emitting fumes/gases... I think you would need to be more concerned with pretty much anything else in your home emitting gases... your carpet, leftover dryer sheets, and more. There are far more "gas emissions" from other places than the synthetic batts.
