One drawback to 8-way hand tied seating is the cost due to the labor
involved in this type of construction. Sofas made in this fashion can retail for
several hundred dollars more than sofas made using Pirelli webbing
which uses a series of springs or coils that are covered by a synthetic
webbing. An advantage of the Pirelli seating system is that it is
less expensive to repair compared to a 8 way hand tied sofa.
But, ultimately the choice is up to you. Dependent on your needs is what determines the best sofa for you and your family.
The
traditional method for creating support in sofas is called 8-way hand tied. Within
this constuction method a series of twine is hand tied in eight different
directions. Of course, the advantage of this is durability. Sofas
made this way have been known to last for many decades.
