Laying comfortably

I bought a wedge pillow and a half moon pillow (for under the knees) off of amazon.com where I found the best prices plus delivery was free.   I used them for the first 3 or so weeks.  I could only sleep on my back.  I had an extended tummy tuck.  To this day I am still sleeping on my back but last night I laid on my side for the first time and was ok.  Its been 7 weeks since my surgery.  The pillows and the toliet seat riser (also amazon purchase) was a big help for me.  I didnt see the need for a chair rental.  I did ok with those pillows and some additional pillows. 

my surgery is Friday morning, so I guess I'll just have to try the wedge pillow under my back (and some others too, I'm sure) and hope for the best. Unfortunately, renting/buying a recliner or hospital bed isn't an option... Thanks for all of the responses!
