adenocarcinoma - lobectomy - and a comfy chair

Hello, 

My name is Sara and I was just diagnosed with stage 1 adenocarcinoma of the right upper lobe of my lung.  Trying to prepare for recovery after surgery.  I have heard that a comfy recliner is a must because it is too hard to breathe lying down.

My doctor says the chair wont make any difference.  I still think I should be on the look out for a soft place to land. 

Any thoughts?

Thank you,

Sara
