Abstract: A system for producing adjustable articulated beds. These beds use measurements taken from a particular human form applied to the bed construction. All beds made using this system have the following in common: a standard distance of four inches from the top of the intended user's head to the head end of the mattress; a mattress that increases in length as the bed is articulated upward and decreases in length when returning to supine position thus matching the change that occurs to the posterior length of the user with no slippage; standardized articulating mechanisms, to articulate the thighs and legs plus and increases the length of the thigh supporting sections when articulated upward, thus matching the movement of the human form; and standardized orbiculators to articulate the torso.
