I am a long-term planner. We want our present home to be so safe, comfortable and convenient that we can both (especially the lone survivor) live in it for the remainder of our lives, if/when physical and mental health decline.
I've always regarded good sleep as the cornerstone of good physical and mental health, starting with with the comfort of the bed and bedroom. We've already reaped the longterm benefits and the older we get, the more important health and energy become.
In older age, floor space in the bedroom can become a consideration. One might need future room for mobility aids and a helper or carer. ( zimmer, wheelchair. Commode?).
This is perhaps the last bed you will ever buy; the one you'll be using when you are much frailer than now. Think hard about the size of bed, and bedroom layout, that best suits a single old person. If you have the money, spend it wisely.
