What makes seating sustainable?

Sustainable seating uses materials with verifiable certifications — FSC-certified solid wood, recycled plastics with documented post-consumer content, low-VOC foams and finishes — and is engineered for repairability and decades of use rather than a few seasons.

What certifications should I look for in seating?

Look for FSC certification on any solid-wood frames, GREENGUARD Gold for low chemical emissions on upholstered or composite pieces, B Corp certification on the manufacturer, and ISO 14001 (Environmental Management) on the production facility.

Which brands does Comosum carry for seating?

Ethnicraft (FSC oak, teak, walnut chairs and sofas), Heller (recycled polyethylene seating made in NY), Varier (Norwegian ergonomic seating), Greenington (GREENGUARD Gold moso bamboo), and Cane-Line (Danish outdoor seating in FSC teak and recyclable rope).

Are these chairs and sofas suitable for both home and commercial use?

Many are. Heller's recycled-polyethylene seating is specified for hospitality and contract use; Cane-Line's outdoor seating is rated for commercial patios and rooftop bars; Ethnicraft solid wood is built to residential and light-commercial standards. Check the individual product page for contract-grade ratings.

Do these ship from a US warehouse?

All Comosum orders ship from a US warehouse with standard freight options nationwide. Trade pricing is available for interior designers, architects, and commercial accounts.
