The frames are constructed with all solid kiln dried Hardwood and engineered wood products. The stress points are reinforced with blocks to secure a long lasting frame. The sinuous springing system is manufactured with a reinforced 16 gauge border wire to maintain a uniform seating. Double springs are used on the ends nearest the arms to give balance in the seating. Cushions are made from hi-density foam cores with Dacron Polyester wrap to provide longer life.
