quality doesn’t come cheap, but a good-quality sofa will stay more comfortable and retain its looks for a long time. Consider buying the best quality that you can afford.
The eight-way hand tied springs system is one of the best support systems. The craftsman connects each spring to the adjoining one with a strong twine. The twine passes front to back, side to side and then diagonally in both directions, thus tying each spring securely. Another method is sinuous spring construction. Sinuous springs are “S”-shaped and run from the front of the seat to the back. These springs are supported by additional wires that cross from side to side. This also makes for a strong seat, and it might be the preferred option in a sleeker style or smaller frame because it requires less space.
How long a sofa will last and retain its shape depends largely on the frame, and a high-quality sofa always has a strong, sturdy one: The best frame is made out of kiln-dried hardwood. The process of kiln drying removes all moisture from the wood, enabling it to retain its shape and stability over a long period of time. A frame made of green wood can shrink or crack as it dries. Softwood can bend and break easily, while knotted wood is prone to cracks.
