Craftsman-built frames are constructed using solid, reinforced, laminate hardwood for lasting strength and superior stability. Arhaus upholstery is made using wood certified by the Sustainable Forestry Initiative. Frames feature a recycled-steel Flexolator suspension system beneath seats for evenly dispersed, firm yet flexible comfort. Backrests are sustained by flexible, sinuous springs for resilient support and stability. Upholstery is padded with dense, eco-friendly foam made partly from sustainable, plant-based material. Seat cushions are padded with poly-fiber to create a relaxing, “sink-into” feel. Channel-stitching keeps padding in place for added resilience.
