Breastfeeding pillow

Would you be okay to let your MIL make you a breastfeeding pillow or would you recommend that I get one that is made by a breastfeeding/baby company? FTM looking for thoughts from mom’s who have breastfed and know the comforts needed for it.

I’m just worried about lack of support and if the pillow doesn’t work for me, I will feel bad that I can’t use it and my MIL has never breastfed her kids or had newborns (kids adopted as toddlers) so I don’t want to hurt her feelings if it doesn’t turn out right.
