Safest baby sleep pillows recommendations?

I write this knowing that The LeachCo. Podster isn’t recommended for overnight sleep, and in saying that, we had to use it with my first child since she had reflux and it put her at a slight incline and helped TREMENDOUSLY. I was going to register for a dockatot this go round and then i read where it also isn’t safe for a baby to sleep in overnight. Has anyone heard of any horror stories with either The Podster or The Dockatot? I scoured the web to see If i could find any terrible cases such as SIDS when using either but instead i found nothing but 5 star reviews for both?
