Abstract
Our invention is related to a pop-up bed frame. Aspects of our invention include a bed-frame positioning assembly for raising and lowering an upper frame in a controlled manner. A bed-frame positioning assembly generally includes a set of scissor arms that is operatively coupled to a biasing member. Force exerted on the set of scissor arms by the biasing member either opens or closes the set of scissor arms, thereby either raising or lowering an upper frame coupled thereto.
