I think that is a great idea! I actually slept in my recliner chair in the living room for about a week.
I then moved into a room that had a bed that was softer than mine and lower so that I could get in and out.
I live in a one level home.
Not to give TMI, but I would get spasms when I would sit to use the toilet, that my hubby would have to come get me off.
You will probably need a walker to get around and get you in and out of bed and on and off the toilet.
As far as the toilet, you might want to have the toilet paper ready before you sit down IF the holder is not right near you.
Showers feel great but you need to prepare for them, too.
If you have a free standing shower, that would be best.
If not, get help to step in and out of the tub.
Have grab bars available.
You do not have to get the permanent ones, they do make good ones that use suction.

Hope this helps and prepares you.
