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.
Kiln-dried frames are superior because you can be sure about the reduction of the moisture content to a satisfactory level. Another thing to remember about sofa frames is that a sofa frame that is made of kiln-dried hardwood is a much better choice than a softwood frame even if it is kiln dried. When you look for frames that will last, make sure to ask about how it has been constructed because that is just as important. A well-constructed frame has reinforced joints that are dowelled and glued and uses screws instead of staples.
Down used in combination with other materials is also a good option but also another expensive option. Pads made out of a Dacron polyester fiber and down, known as Blendown pads, are wrapped around high-density foam. These pads can also be used with springs that have been wrapped up in foam. High-density foam surrounds the springs, which are then wrapped in down pads. The result is a soft surface with a strong, resilient support inside. This is a good option because the cushions do not lose their shape easily.
