Now that you have considered the frame and seating support, it is time to look at what kind of filling is used for the cushions. The most common filling is high-density polyurethane. The higher the density, the firmer the cushion will be. Foam can be wrapped in softer material or cotton to make it softer. Dacron-wrapped foam is the cheapest option, but it won’t last as long.
There are alternatives to kiln-dried hardwood frames. Metal sofa frames are available, too, but metal can be prone to oxidation along with seasonal changes. Changes in humidity can affect metal frames, so look for one that has been treated to protect against atmospheric changes. Plywood frames as long as they are thick enough can also work well. As a matter of fact, many leading manufacturers now use well-constructed plywood frames.
This is another one for design pros and the design risk takers. In large rooms, a backless sofa (or chaise) is perfect for breaking up the room and creating conversation areas.
