Excellent Experience
John Martin | May 29th, 2019
All around excellent experience, from requesting color samples, to ordering, to receiving product, to the quality the of foam not to mention the reasonable prices. My drum studio looks great with 3"x 24" x 48" acoustic wedge foam adhered to pegboard panels. Glue up was a breeze! My 3rd order from Foam Factory...consistently excellent.
Best deal around
Chris H | May 9th, 2019
After my purchase, I was contacted by Foam Factory to make sure I was satisfied and was given a link to this survey. I was shocked that nobody has left a review yet... I guess I'll be the first! I did a lot of price to value shopping before I bought the materials to dampen my new drum studio. Compared to every other site or outlet I could find, Foam Factory BY FAR was the best quality and best deal. For comparison, 28 3" 12x12 foam wedges on Amazon was roughly $125-150 for 'decent' quality stuff with decent reviews. I bought 48 3" 12x12 wedges for less than $90 from Foam Factory! That's 12 extra wedges for $40-50 less and the quality is fantastic! They also have the best deal on bass traps and corner wedges from what I could find available to the public. The quality is also bar-none. While my wedges/traps did come vacuum shrunk and slightly squished they expanded to normal size in less than a day (took about 12 hours) and hold their shape perfectly. They also do not have any odor like some of the cheaper brands. Anyway, my advice is to stop looking, this is the place to buy from!
