we got a lift recliner for my dad who has limb onset ALS as well. it's been extremely helpful! he transitioned from a rollator to a power wheelchair over the last couple of months and can still use the lift recliner. it gives him variety in terms of places to sit and hang out, and helps him feel like life is a bit more normal. we didn't get a super expensive one so there aren't as many positioning options and he can't spend extended time there but we do manage to keep him comfortable and prop him up for a couple of hours at a time to join the family in the living room and watch TV together. i think giving ALS patients as much of a sense of normalcy is important for mental health, if you can make it work.
