After trying chairs, recliners,beds,couches; after going from room to room, wandering most the night I became desperate and sought professional help for my sleeplessness problem. A hospital bed was prescribed, and in short order my old bed and mattress were gone, replaced by an electrical marvel that It could do everything. You could adjust for bent legs and straight back; bent back and straight legs. Head high, feet low; feet high, head low. It came with a control that put you in almost any concievable position. But the bed was not designed by some simpleton so it would jerk you around and up and down at the press of a button. Nosiree. Changes come gradually and you can't tell right off if you are getting the change you want. You wait for the bed to utter a few moans and groans. Then it very gradually makes its move; accelerating as it goes. By the time you have a clear idea of what the bed is doing you may find yourself sliding to the foot of the bed. You pushed the wrong button! A call of nature may cause you to seek a lower bed for easier dismounting.. If you press the up button by mistake, when you get to the edge of the bed youi may find yourself looking down into an abyss, a daering bungee jump. Don't wait till the last minute to answer nature's calls.It takes the bed a while to slow, stop, reverse. In time I will master this gadget and it will prove its worth.
