This is the case of the sofas, as we use daily to sit or lie down, so it’s normal to lose their strength over time. Steepest parts of the sofa just sinking and lose their original appearance, the cabinet is no longer comfortable. If you do not see an option to change the overstuffed sofa the whole, the problem is the filling
To address the overstuffed sofa we have to know that the problem originates in the filling. If our sofa cushions have removable covers, what we can do is spread the filling. With a few sharp raps it will suffice to fill back to its original place. However, if it has suffered a lot, we will replace it with a new filling. Remember that to get the original appearance, the stuffing should be the same or similar to the above.
Another alternative is to fill the sheath of a standard and economical cushion overstuffed sofa. At the end, we would have to enter the cushion on the overstuffed sofa cover required by the settlement. If access to these parts is more complicated, for example, in the case of pads not removable, we will have no choice but to open one of the seams. The process is the same as with removable cushions.
