High productivity configurable workstation with multi-tiered work platform

A mobile, multi-tiered food preparation workstation comprising:

• a plurality of vertically-extending support posts, wherein each vertically-extending support post comprises a lower end and an upper end;
• first and second horizontally-extending frame rails, wherein the first frame rail comprises a first rail end and a second rail end and extends a first rail length between the first rail end and the second rail end and wherein the second frame rail comprises a third rail end and a fourth rail end and extends a second rail length between the third rail end and the fourth rail end;
• wherein the first frame rail is supported at first rail end by a first upper end of a first vertically-extending support post of the plurality of vertical support posts and at the second rail end by a second upper end of a second vertically-extending support post of the plurality of vertical support posts;
• wherein the second frame rail is supported at the third rail end by a third upper end of a third vertically-extending support post of the plurality of vertical support posts and at the fourth rail end by a fourth upper end of a fourth vertically-extending support post of the plurality of vertical support posts;
• a plurality of casters, wherein a respective caster is attached to a respective lower end of each of the first, second, third and fourth vertically-extending support posts of the plurality of vertically-extending support posts;
• wherein the first frame rail extends along a first horizontal axis and defines a forward boundary of the workstation and the second frame rail extends along a second horizontal axis and defines a rearward boundary of the workstation, wherein the forward boundary and the rearward boundary are spaced apart by a distance to define a workspace intermediate of the first and second frame rails;
• wherein the first frame rail defines a first support surface and a second support surface, wherein the first support surface is located at a first vertical distance from the upper end of the first vertically-extending support post and extends the first rail length, wherein the second support surface is located at a second vertical distance from the upper end of the first vertically-extending support post, wherein the second vertical distance is less than the first vertical distance, and wherein the second support surface lies inward from the first support surface;
• wherein the second frame rail defines a third support surface and a fourth support surface, wherein the third support surface is located at a third vertical distance from the upper end of the first vertically-extending support post and extends the second rail length, wherein the fourth support surface is located at a fourth vertical distance from the upper end of the first vertically-extending support post, wherein the fourth vertical distance is less than the third vertical distance, and wherein the fourth support surface lies inward from the third support surface;
• wherein the first and third support surfaces of the first and second frame rails lie in a first common plane and the second and fourth support surfaces of the first and second frame rails lie in a second common plane;
• and
• at least one frame member supported by at least two of the first, second, third and fourth vertically-extending support posts at a fifth vertical distance from the upper end of the first vertically-extending support post.
