Anniebach I assume you can make your own transfers, so can get from bed, to wheelchair, wheelchair to loo, etc. etc. Also, will depend on whether you need the same chair when you go out (although I do know you do not do this very often).
My ex-husband used wheelchairs indoors for many years, but required hoists for transfers. There is so much to choose from, Some will lift you to standing position, others are just for indoor use, other can do both indoor and outdoors. You also need to ensure that ANY chair you use is really suitable for you and gives proper support to all parts of your body.
Easy to have a look at such catalogues like Careco - but would have thought the first place to start is to have a consultaion with someone from your care team. You do need to be sure that all your doorways are wide enough for a chair, and you may need some of things like light switches can be lowered to be accessible from the chair. Also, in your kitchen, might need to take away the base unit so you can get to the worktop whilst still in the chair.
Most chairs, simply plug into the electricity for batteries to be re-charged at night.
If you can manage without a chair, then a mobility trolley is very useful to help you get around safely at home and not have to try to carry things.
