Natural Acoustics sound panels

Natural Acoustics sound panels and bass panels. I only found them by complete accident typing in natural fibers. Their offerings are very reasonable and come in numorous colors. Have any here bought their panels? There made using natural fibers such as cotton and denim.They also sell mounting brackets made of natural pine wood.
Do they offer any controlled measurements of the absorption characteristics of the products?

Absorption Coefficients @ Octave Band Frequencies (Hz)
Thickness 125 250 500 1000 2000 4000 NRC
3” .95 1.30 1.19 1.08 1.02 1.00 1.15
5” .97 1.37 1.23 1.05 1.00 1.01 1.15
Natural Value
They offer this on their site. Their panels are rather thick 6" bass and 4" for acoustic sound panels.A set of 3 24"X24"4" will run only 119.00 for natural weave and colors an extra 10.00. The bass traps are 2 for 99.00 if you buy the 24"x24"6" panels. Slightly larger are a fraction extra in price. Mounting wood brackets are 3 for 39.99 but I am sure many will make their own for less.
Wow. Those are impressive and surprisingly consistent values. Price is good, too. I have contacted them for more information. Thanks.

OK, I tried most of the reasonable searches for "natural acoustics" and haven't found this yet. Link please.
Seriously? Google "Natural Acoustics sound panels" - the title of the thread
FYI the cheapest panels I've found online are ATS Acoustics (link provided for the search engine challenged), whom I've also bought from and can't complain about service or product. 2' x 4' x 2" thick panels are $48.95, 4" thick panels are $59.95. However, the Natural Acoustics panels give you an extra inch thickness for each of the common sizes. They look nice -- please report back if you go with them.
