Didn't try out that one. A regular pillow (sleeping one) worked for me fine. I used to have a lot of pillows at my back for support, and one to support the baby.

What about arm pillow(that is wrapped around arms)?

U should get a feeding pillow which is u shaped/c shaped.. do not get the pillow that comes with the straps to tie it around the waist. I got a similar one from the hospital, and it was an absolute waste for me.
