Dual-function seating that converts into a sleeping surface — sofa beds, futons, and similar pieces — is carved out of the broader seating classification precisely because of its bed functionality, and the exclusion of garden and camping equipment keeps the scope focused on indoor residential and hospitality furnishings. The convertible-bed distinction matters commercially because these products compete directly with standalone beds and sofas, and retailers often import them as a cost-efficient alternative to separate bedroom and living-room pieces. Frame material (wood, metal, or other) may further subdivide classification at the tariff-line level.
