Has anyone used this as a sleeper?

I did my research and this is not recommended for unsupervised sleeping but the doctor has recommended no bassinet unless we elevate it which he roles down the bassinet and use blankets to get his butt in place which is dangerous also. He has a choking episode and been diagnosed with reflux. I just want to know if anyone used this as a sleeper? What the outcome was? She told me there is no logical reason that this is unsafe but idk.
