Fit Cut Foam into Built-in Structure

What happens here

Take the freshly cut foam pieces and carefully place them into their corresponding sections within the built-in bench structure. Ensure that each piece fits snugly against the edges of the built-in, without excessive gaps or buckling. This step confirms the accuracy of the measurements and cuts, establishing the basic form of the custom couch.

Goal: Once cut, the custom-shaped foam pieces are carefully placed into the built-in bench sections, verifying that they fit snugly and correctly, forming the seating and backrest components.
