@Markieamark Welcome to BoneSmart! There are several threads about recliners - you can use the search function here and put in "recliners" ... not all threads will be in the shoulder section but that's OK. Since you are having the right shoulder done first it might work best for you to look for a recliner to either rent or buy that closes the foot rest with either a button (electric) or closes by pressing with your legs. A hand lever is usually on the right side and that would be difficult and painful to use after a shoulder replacement.
Start practicing now to be one handed for a while ... especially if the right is your dominant side. Shoulder replacement means you'll have a sling with a padded bolster to wear for about 3-6 weeks. You can take that off to shower, dress, and do some gentle "swing the arm" exercises that you will be given in the hospital. But it is a bit awkward to wear that (not uncomfortable). You will be able to use the right hand to hold things down while using the left hand to do the work .... like opening a jar or spreading mayo on a sandwich. And the sling does make any clothing adjustments and hygiene needs a bit tricky.
As with any joint replacement you will need to practice patience .... heal first then work on range of motion and strengthening. And shoulders are complex joints with many muscles and tendons that will be traumatized during this surgery so they all need to heal which takes time.
I've had 2 shoulder replacements though mine were both standard ones not reverse ones. For me it took about 5-6 months to heal then go through the full physical therapy regime to get each shoulder back to full functioning. But everyone is different.
Best of everything for you! And do ask any questions you might have.
