Mid-century Furniture Finds

Found these amazing danish-style chairs and sofa at an estate sale. Frames in nearly new condition with little plastic feet on bottom still intact. Wood appears to be oak or maybe walnut — not sure. Stamped "Ridgeway Insp." on bottom of all pieces. Have original cushions for both chairs but not for sofa. Can anyone help me identify them more closely? Assume they weren't made in Denmark...but style and condition is so good!
