Hi ch47,
Bed or couch depends only on how much support each will give.
I just wanted to lie still on my very supportive and comfy bed. My couch, I thought was great before the treatment but during recovery it didn't quite feel good enough.
The best thing was in the shower: I had a shower seat in the shower, and a hand held shower head. These were very helpful.
I put items that were used a lot.. cup, plates, pot, etc, anything that I usually used, so that I didn't have to bend or reach. Everything at a very convenient reachable level. Also stuff in the bathroom,; you won't want to have to struggle to reach your shampoos etc. Also your fridge- items.. like milk, so there is no 'twisting' to reach something. Comfortable ice packs. (If allowed)
Have some favourite meals or beveridge that you enjoy, made up ahead of time- stocked and in the freezer, just ready to grab. Extra toilet paper on the back of the toilet.. little things like that are marvelous helps.
Maybe ask your friends to plan a certain day to visit, so everyone doesn't arrive at the same time!
Perhaps check your slippers, in good repair and supportive- no trip hazards. Maybe a slip-on pair of sandals would be best.
Put away any little scatter mats or things that might be a hazard when walking.
Just go through your normal day, checking that stuff is in easy reach and good repair.
Anything that makes life easier and safer is great! This is to make life easier, good self- care and to speed your recovery.
All the best!
