We have a great recliner, and I used it during the day, but had no need for it at night. It's good for daytime inthat it keeps your head elevated, which may create less likelihood of fluids gathering in your lungs.
If you're sleeping prone in the hospital bed, you can probably sleep just fine in your own bed. Beware also of sweats, when sleeping, as some of us developed severe sweating (as in soaked), especially at night. If you have a leather recliner, you moght want to put a pad on it.
The Heart Hugger or Heart Pillows are also optional. Some people swear by them, others (such as myself) do fine without them.
Best wishes,
