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.
This drastic reduction in wood´s moisture content is important so that the wood doesn´t warp or shrink with changes in humidity and temperature. Warping or shrinkage can destabilize your sofa, and even cause it to lose its shape. You would not see that happening in a quality sofa. Air drying can also work well, but since often times the process is not controlled enough, so you cannot be sure that the wood‘s moisture content is sufficiently reduced.
The seating support is also an important component in determining the quality of a sofa. It works in tandem with the frame and the filling. A sturdy frame provides an anchor for good seating support and filling augments it. You should always test the quality of seating support by sitting on a sofa before you buy it. It shouldn‘t sag, and it should provide good support in the seat and in the back.
