breastfeeding pillow

Hello mommies, what's the best and practical breastfeeding pillow but not too bulky? I'm using one from bloom but the sides are not sturdy enough, my husband still puts something like a small pillow under the side so I can rest my arm holding my baby's head while breastfeeding but I can't do it alone when my husband isn't around. My back and arms are already hurting. TIA ?
