1. A bed comprising:
a base forming a surface;
an upper frame including two or more frame members at least partially forming a rim around an opening into an interior space of the bed, and
walls extending upwardly from the base to the upper frame and around the surface to partially enclose the interior space of the bed; wherein
one of the two or more frame members is a movable frame member that is movable relative to another of the two or more frame members in order to adjust a height of a portion of the rim formed by the movable frame member relative to the base,
the movable frame member is movable between first, second, and third predetermined positions at which the height of the portion of the rim is at first, second, and third respective predetermined heights relative to the base,
the upper frame includes a locking mechanism configured to selectively lock the movable frame member at the first and second predetermined positions, the locking mechanism including:
a hinge assembly including a first hinge component and a second hinge component that are pivotally coupled together to support pivotal movement of the movable frame member and the other frame member relative to one another about a first axis, and
a first locking component slidably coupled to the second hinge component such that the first locking component is slidable relative to the second hinge component in a direction with a component parallel to the first axis in order to lock the position of the first locking component relative to the second component, and

the position of the movable frame member is biased to move from the third predetermined position toward the first and second predetermined positions.
