I'm one of the ones that used Nu-Foam,so my advice is return it and get your money back!!

I used it on a chair that needed recovering,and in less than 6 mos it was as flat as a pancake.My friend had the same experience.It was too late for me to get my money back,but i did let Joann's fabrics know that it was useless stuff.

I went to an upholstery shop and got my foam there,and they cut the size i needed for no extra charge,so i'd go that way if i were you.

I buy the green foam at Joann's or foam from the Foam Factory.

I agree with others not a good product, does not have the recovery like the green or white rubber foam.

Thanks for all of the responses! I'm on my way to exchange the Nu-Foam for the green foam. Thank goodness I found out before I did all the work!!
