My husband and I desperately wanted to remain in the same bed as ALS has taken so much from us and we weren't prepared to give up sleeping together. Consequently, I spent months of sleepless nights trying to move his rigid legs so that he could get some relief. I looked at a number of adjustable beds but had concerns about how they would work. We finally got a Carroll hospital bed. It has a solid foundation (instead of springs which made it sink when he was still able to sit on the edge of the bed for transfers). It is electric and fully adjustable. We now roll it to one side of the room so that he can transfer from his wheelchair or commode to bed and once he is comfortably in bed, we push it next to our Queen-sized bed. There is a small gap between the two which I fill with a rolled blanket (affectionately called the "crevass filler" as we like glaciers). Because he can raise and lower the entire bed, the two beds are flush against one another. He is able to adjust the head and legs himself which means less accumulation of saliva at night and reduced swelling in his feet. It means I get to sleep! In the morning I roll the beds apart which allows me to turn him onto one side and the other for bathing and change of position. I wouldn't be able to do this very easily or safely (for my back) had we opted for a king-sized split bed. After so much worry, the quality of both of our lives has been very significantly improved. I hope you find a good solution for you and your wife. These decisions are SO stressful!
