Most use synthetic rattan (PE rattan or poly rattan) for the weave and polypropylene or similar plastics for molded parts, with many models mounted on powder-coated steel frames for added strength and weather resistance.
Some models include built-in under-seat storage or a storage compartment, and a few sets include an ottoman/footstool that doubles as a footrest or extra seat.
Widths in the listings range from about 40.7 inches up to 69.3 inches. Listed seat heights (floor to seat top) range roughly from 11.8 inches to 15.7 inches.
Listings commonly describe synthetic rattan as weather-resistant and UV-resistant and note water-resistant or outdoor-grade construction. Many product details still recommend protecting the bench with a cover during severe weather.
Many listings include padded cushions with removable, zippered covers that can be washed. Common care recommendations are spot-or-wipe cleaning for frames and removing cushion covers for washing per the care label.
Some models convert from bench to a day bed or sofa bed and offer multi-position or reclining backrests, adjustable armrests, foldable side tables (some with gas springs), and removable cushions.
