Can deck boxes be used for seating? What load can they safely hold?

Yes, many models are suitable for occasional seating. Look for the “sturdy design for seating” label on the deck box carton (this excludes models such as the DB6300, DB6300B, DB8300, and DB10300).

Depending on the size, one or two people can sit on deck boxes: small deck boxes can hold one person (about 150 pounds); the larger deck boxes can hold two people (about 300 pounds). This assumes ordinary care will be used while sitting.
