I am 3 weeks post surgery for the same thing you are going to have.
Before surgery I cooked meats, many, and froze in serving increments in the freezer (I also have large chest freezer). This way hubby would only have to heat meat and add veggies to meals. If no diet restrictions you could purchase frozen dinners and have handy in freezer for 3 weeks.
Bought a tall plant stand (from Big Lots, $15) right height to be a small table next to recliner for phone, meds,
"bell", etc. (put piece cardboard or other on stand so things do not fall through). Also bought low plant stands (Dollar Stores..$3 each) for bathrooms, toilet paper holder was on the wrong side. I pre-folded toilet paper in increments for use and stored in container on plant stands, made it more convenient, about 12 rolls toilet paper worth and will last about 3 weeks. I was not allowed to use arm/hand at all other than to stretch fingers for 2 weeks. Still not allowed to use shoulder myself for a total of 6 weeks, will be in sling that long. I am having passive physical therapy 3 times a week starting after 2 weeks from surgery.
My shoulder was the left this time and the lever on recliner was on the right, worked out just fine. I will have surgery on the right shoulder later and plan on purchasing a recliner with "power" and control on the left or possible one that will have long enough cord to put on the left or right. Recliners are anywhere from $300 to over $1,000.
Before surgery I prepared the recliner by covering with folded sheet, waistband elastic around back in two places, one for folded towel to support upper arm and it not fall out of reach, another for rolling a hand towel around for a neck pillow. Had a round long large neck pillow to use under knees (footrest and chair had a dip). Keep small pillows handy to stuff here and there for your comfort. 14" inch worked well for me, they were not fat, on thinner side from long term use.
Put a cover sheet and afghans handy for cover, I was very cold after surgery.
Buy about 6 ice packs and keep in freezer, you will need them, helps pain and swelling. Wal-Mart has them in area where heating pads are. Mueller Cold/Hot pack 6"x10" was the most practicle size. I also had two larger ones that worked good the first few days, covered more area. Placed a light weight hand towel over shoulder then put ice pack on.
If you have the option of having a "nerve block" that lasts 3 days, go for it. I had that and it was great, lasted 3 days and 4 nights. Mine had a container of med that hung around my neck. The first 3 days will be the most painful. A single nerve block shot will last only 18 hours at most.
Sleeping in recliner for 2 weeks worked best, could not lie flat in bed or get out of bed, too weak in beginning.
No way could I go to beauty shop to have hair washed, shoulder incision would land on hard surface and would be unable to get back up out of the chair. I cut a hole in end of garbage bag for my head. pulled over body (cute dress) and hubby taped opening to my neck and washed my hair in the kitchen sink. This kept the incision dry.
In addition, have things on hand in case of severe constipation from narcotic pain meds. Miralax, stool softeners, prune juice, things for low water enema (Fleet will not work on rocks). Drink, drink, drink, drink 2 liters or more water daily from the beginning in hopes you can avoid this problem.
I must head for PT right now, if I think of other things will let you know.
