Between these years Breuer experimented with flat aluminium in his furniture. It was not as strong as tubular steel but was considerably cheaper. The seats were targeted at the mass- market and were sold in Wohnbedarf in Switzerland. The concave bands at the back are structurally necessary but at the same time are aesthetically pleasing.

The seat above is named the Armchair, Model No. 301. It is made from painted aluminium with a painted and moulded laminated seat and back.

The image below is of model No. 313. The sun lounger has a bent aluminium frame with aluminium slats and beech armrests.
