Are you sinking into the furniture seat when you sit? If so, the issue may not just be your foam. A simple test you can perform is take off the seat cushion and press down on the decking area to see how badly it is sinking or not.
You see, underneath the furniture seat is a foundation that is commonly made up of either a plywood board, webbing, zig-zag springs, or coil springs on top of webbing. To determine what the specific issue may be with your furniture’s seat foundation, we can provide a free in-person assessment with an appointment.
If your seat foundation have only a plywood board then the issue is not the spring or webbing but likely the foam. You can order foam replacement through us.
If the seat foundation have webbing only then the issue may be that the webbing is too worn and needs new webbing to be re-stretched. Many imported furniture uses an elastic webbing for the seat foundation. Unfortunately, this material wears down quickly and requires replacement. The traditional method is to use jute webbing which is a more durable material and tightly weaved to create a stronger seat foundation.
If the seat foundation have zig-zag springs the two most common issues are that the anchoring nails on the spring clip attached to the wood frame are coming off or there are no twine tied perpendicular to the zig-zag springs to support.
This is the most challenging of the seat foundation issues to deal with and most typical in antique and vintage furniture. The proper way of tying coil springs is eight knots on top of each coil interconnected to other coils. Depending on what is needed, repairing this issue can be a combination of: (a) reinforcing the webbing with additional new webbing to raise the springs up (b) partial spring re-tie of ripped twine (c) complete spring re-tie and re-webbing.
