What frame materials are used in commercial lounge seating?

Commercial lounge seating frames are typically made of kiln-dried hardwood, steel, or a combination. Steel frames provide the greatest long-term structural rigidity, especially for sofas and loveseats that see continuous heavy use. Hardwood frames (beech, birch, poplar) are lighter and common in mid-grade commercial products. Avoid particle board or MDF frames in lounge seating — they delaminate under repeated stress.
