Here's where most upholstery jobs go wrong: the fabric goes on too early.
The pull is understandable. Fabric is the interesting part. You have the yardage, you've matched the pattern, you want to see the piece come together. But foundation work is invisible when you're done, so people compress it. They spend forty-five minutes on springs and three hours on the cover. Then they wonder why the seat sags in a year.
The sequence exists for a reason. Every step constrains what comes after it.
Strip first. Completely.
Before you assess anything, get down to wood and springs. All the old fabric, all the old foam, all the old webbing. Strip everything. Not halfway, not "mostly." If you assess a frame while it still has webbing and padding on it, you're reading the piece wrong. Joints that look like minor repairs can turn into something else entirely once the load comes off and you can get your hands on the structure. You can't feel racking through three inches of foam.
Strip to wood. Then look.
Assess before you build.
Four things: frame structure, spring condition, webbing platform, tacking rails. If a joint is loose, fix it before anything goes back on top of it. Upholstery doesn't stabilize a bad frame. It hides one — for a while. You will be the person who gets the call when it fails.
Build the foundation like it's the job.
It is the job. Springs, webbing, foam, dacron — this takes three times as long as installing fabric and zero of it is visible when you're done. The client doesn't see it. You build it anyway.
Coil spring retying is slow work. Do it right. Sinuous spring replacement means matching the original gauge, not whatever's in stock. New webbing gets stretched — actually stretched, tight enough that it's still supporting the foam layer in six months, not just today. Cut foam to the correct density and ILD for the application. A dining chair and a sofa need different specs. Wrap with dacron batting and take the time to get the profile right, because the profile you build here is the profile you're delivering.
Cover fabric is last.
This is not a moral statement. It's a sequence. The visible work happens last because it only works if everything before it is done correctly.
The sequence for a standard seat cushion:
- Strip to frame
- Inspect and repair frame — to bench if needed
- Springs — retie or replace
- Webbing — stretch and tack
- Foam — cut to dimension, glued to platform
- Dacron — layer and trim
- Fabric cut, with pattern alignment confirmed
- Pull and tack, center-out, all four sides, corners last
- Final check under raking light — seams, tension, no pulls or puckers
The governing principle throughout is center-out. It applies to webbing, to foam attachment, to the fabric pull. Establish center first. Tension radiates outward. If you start at a corner, you're chasing errors for the rest of the job.
Rushing to step seven because that's the part you're looking forward to is how you end up with a piece that looks right and fails in a year. The foundation is where the piece is actually built. The fabric is just how it gets handed over.
Do the invisible work. That's the job.
