I just use my bed. Sometimes I like to sit up, other times I like to just lie down. If I had enough room for it and money to buy one, I would choose a nice Lay-Z-Boy type of chair that I would be comfortable sleeping in as well as sitting. My home dialysis unit provided the medical scale and a hospital bed table, but I’m on my own as far as chair or bed go. I only have a small apartment, but ideally, I would prefer to have my dialysis setup in a separate den or room. In that case, I would get a chair that I could sleep in for nocturnal. I find it less convenient using a bed because it limits where you can place things that you need for or during the treatment (because you end up having to have everything on the same side - dialysis machine, centrifuge for blood work, needle table plus a place to put sundries like food, drink.
