Absolutely! It is the best option available! Then, like Manu, you can change your system three times a year wondering what is wrong with the sound.
There are lots of misconceptions and myths around about sound absorption. An egg crate, for example, is made to store eggs, not diffuse sound. A mattress is made for people to sleep on, not absorb sound. Why? Simply because, materials have to have certain density before they can absorb or diffuse sound. If you use a mattress, you have to stack at least three mattresses together to get a decent NRC of even 0.5. Professional sound absorbing materials are made with a enough density to achieve the NRC claimed.
In addition, mattresses will tend to sag. If stuck permanently to the wall, they will absorb (not sound) but a lot of dirt, and start smelling.
Before using or thinking of using any material, the first thing to do is to find out it's NRC.

I was wondering, if anyone tried using the inexpensive cotton/coir mattresses as material for treating room acoustics. looked like a cheap option, any opinions suggestions ?

This is interesting. Ofcourse NRC is an important value, but If high NRC is the target then would the room not become "anechoic" robbing of liveliness.
Since we are lucky to have coir in abundance which western countries may have not exploited was hoping it could be secret to be discovered. I just googled up and got some hits for rubberized coir for acoustic, Will dig in for more details and update.

Thank you Suri. You have not only proved the effectiveness of the coir and other mattresses, you have also provided a detailed BOM and an instruction manual. Can we add a 50K a month as alimony?Assuming that with all the bolts and pits, the walls do not crash.

these habits have to be supported by the (audiophile) ex-husband.
