An adjustable platform extension bracket for work platform systems comprises a post member having two posts joined by a plurality of positional structures. A first connection portion forms a first channel such that the first connection portion is symmetrical along an axis parallel with and passing through the channel. The post member is slidingly engaged in the first channel such that at least one of the positional structures is positionable in the channel. The bracket does not require any diagonal support. The dimensions of work platforms, particularly suspended work platform systems, may be extended using the adjustable platform extension bracket.

An apparatus includes a platform having a first end and a second end and a handle. The apparatus includes a first leg assembly rotatably attached to the platform in proximity to the first end. The apparatus includes a second leg assembly attentively attached to the platform in proximity to the second end. When the first and second leg assemblies are essentially perpendicular to the platform, the apparatus is in a use state and the user is able to stand on the platform and be supported by the first and second leg assemblies. When the apparatus is in the use state, the user is able to pick up the apparatus by the handle with only one of the hands without tipping the apparatus. A method for a user with hands to stand on an apparatus. A work platform having legs which are coplanar with the platform when the legs are in a closed position. The work platform having a hinge bracket with a tab against which a leg contacts and is stopped when the leg is in an open position.
