Is investing in a breastfeeding pillow a good idea? Is it really worth it?

For my first 2 i use nursing pillow and i think is very useful. For my 3rd one i went to uma at mother n child and use a upright position to latch so the pillow was not necessary. I would think the latching postion is helpful especially when u are outside no pillow ard. If you can get the hang of upright latching then pillow is not required.
