Make sure that you are getting high-density foam because lesser-quality foam can start breaking down pretty quickly, causing sags, and the fabric does not stay taut when that happens. If you want a really soft seat, consider down cushions. These are considered to be the premium choice, and as you might imagine they are also among the most expensive. High-quality cushions have down-proof ticking under the upholstery fabric to prevent feathers from poking through. Cushions filled just with down are high-maintenance and can need daily attention.
Wood can hold a lot of moisture when it is first harvested. What makes a kiln-dried frame better is that the process gets rid of most of the moisture inside the wood. Kilns are huge ovens with very strictly controlled temperatures and humidity. The kiln drying process can remove approximately 93% of the wood's moisture.
Engineered wood is just what the name implies. It has been engineered to achieve its present form. There are two types of engineered wood, plywood, and particle board. Particle board is not suitable for sofa frames, or any weight bearing frames for that matter because they are made from wood chips and fibers glued together. Plywood is engineered by gluing several thin layers of wood together and can be strong enough for sofa frames depending on the type of wood, and the thickness of the frame.
