Construction:
Support Structure/Chassis, Classic or Imperial styles:

Frame Members: one piece "U"-shaped or "oblong"-shaped; bends are mandrill-bent for wrinkle-free bends

Basket Supports: formed to fully support bassinet basket and fully heli-arc circumference-welded to Cross Members; welds are buffed to a smooth, bright polished finish

Cross Members: ends are coped for uniform fitting joints and fully heli-arc circumference-welded to Frame Members; welds are buffed to a smooth, bright polished finish

Cross Brace: ends are coped for uniform fitting joints and fully heli-arc circumference-welded to Cross Member; welds are buffed to a smooth, bright polished finish

Shelf: one piece with front, back, and both sides hemmed; hemmed edges are flanged down creating a unitized top and double-thick angle frame; corners are notched to fit the leg contour; unitized top and double-thick angle frame's vertical flanges are fully heli-arc welded to the chassis' frame members (welds are concealed)

(Note: In models where Shelf is used, the lower Cross Members and Cross Brace are eliminated.)
