This is the other half of a mini series reviewing the green restoration process. We now delve into the world of cushioning and fabric, and explore the many layers not usually seen underneath the final outer fabric.
Just as restoring the frame has multiple steps, see ‘The Chair Restoration Process: Part One, the Frame’, upholstery also has many steps that together create a final product. Each material used is in itself a step since one of the principles of upholstery is working in layers of tension to create strength and shape. We continue in the spirit of ‘quality over quantity’ and happily share the craft that makes green, custom upholstery an art.
Hand tied in 4-way or 8-way method
This is the step I’ve yet to see in the current retail market, and mostly characteristic of antique pieces. As you can see below, the labor is extensive, and requires strong hands, arms, and patience. The industry standard is hemp twine, the same material used for rope, and is incredibly strong when tied into layers. In fact, every old chair/sofa I’ve opened up or seen, 99% of them still have their hand tied springs intact. We’re talkin’ at least 50 years old! 8-way hand tied springs, along with horse hair used in genuine antiques, are the most enduring features of custom upholstery.
Foundational support and shape
The magic of webbing is it’s ability to curve with angles, as well as create flat surfaces. It’s application involves coordinating a webbing stretcher to pull the webbing tight, then stapling in two directions for ultimate security. High end, mass manufactured furniture tends to utilize webbing as the seat instead of using the costlier hand tied coil springs.
Supplemental support and shape smoothing
Also made of jute like it’s buddy Webbing, burlap adds a finer touch to the foundation. It provides a solid base that all later materials will rest on. It is hand sewn using thick nylon thread, and a stitch that both flexes with pressure and remains stationary to the spring or webbing underneath.
Foundational cushioning and support
Up to this point, all the other materials are available at most any upholstery supplier. Coconut coir is hard to find although it was used back in the day, antiques pre mid-century. I hand sew it to all the preceding layers, adding more strength and shape, and ultimately a solid base to support body weight and impact.
Smoothing and Contouring
Commonly used in quilts and blankets, unbleached cotton is sandwiched between the foundation and cotton muslin that will eventually contain it all. It creates a softer line by hiding the rugged foundation; it makes everything look smooth and pretty. It’s kinda like botox filling in the wrinkles so you appear more smooth…. After it is contained by muslin, it is beat with a rawhide mallet to flatten bumps and create a uniform surface. That last part is not like botox.
Contain the foundational layers
Simple cotton muslin is unbleached and has the strength to compress the previous Cotton Batting. If cotton batting is botox, then muslin functions like one’s skin. Unlike the face stiffening effect of botox, the combo of cotton and muslin make for a cushy n’ padded surface. This step is also helpful if you plan to reupholster your furniture every 3-5 years, needing only to replace the outer fabric rather than totally restoring the foundation every time.
Cotton Batting Again
Contouring and Cushioning
More layers are added in anticipation of the final outer fabric. You can still think of it as botox for upholstery.
The final layer
This stage is definitely exciting since we really start to see the piece’s personality emerge. Once I cover the frame, I move onto constructing cushions and pillows which means time spent on the sewing and overlock machine. When determining the shape of the seat cushions, I prefer a paper pattern so that everything is exactly symmetrical. It’s how garment construction is approached and my upholstery teacher never understood the extra work. I also make cotton muslin liners for every cushion and cozy pillow, and invisible zippers make it all look streamline.
