Sew foam, also
known as scrim foam or pleating foam, is a staple material in modern
upholstery, especially when it comes to creating pleated, quilted, or channeled
designs. Built with a t-shirt or brushed tricot backing, sew foam is
specifically engineered to hold stitches without pulling through the foam. This
allows upholsterers to sew directly into the material, forming clean,
consistent patterns in various applications from automotive seating to
motorcycles, boats, and more!
Unlike traditional cushion foam, sew foam is not meant to provide primary support. Instead, it acts as a top-layer material that adds a layer of padding, softens hard edges, and enhances the overall look of a finished piece. By giving structure and dimension to stitched patterns, sew foam plays a key role in achieving that professional, padded appearance seen in custom interiors.
At Albright’s Supply, we offer a range of sew foam options to suit different applications, preferences, and performance needs. From economical solutions to premium and specialty materials, each type is designed to support specific upholstery goals while maintaining ease of use during fabrication.
Our Economy/Regular sew foam options provide a reliable, cost-effective solution for general pleating, quilting, and padding. Available in both 1/4" and 1/2" thicknesses, these foams are well-suited for everyday upholstery projects. While the color and density may vary, they deliver solid performance for standard applications.
For those
looking for consistency in both appearance and performance, white sew foam
offers a uniform option. Available in a 1/4" thickness, it maintains a
consistent 1.4 lb density and 50 lb compression, making it a dependable choice
for projects that require predictable results. It is also compliant with
Proposition 65* guidelines and manufactured to meet California Technical
Bulletin 117** flammability standards.
Pink sew
foam is another consistent option, offering slightly higher density and
compression for added structure. Available in 1/4", 3/8", and
1/2" thicknesses, it provides flexibility depending on the desired depth
of pleating or quilting. With a 1.5 lb density and 60 lb compression, pink sew
foam strikes a balance between softness and support, while also meeting Prop 65*
and TB117** standards.
For projects
that demand sharper definition and more pronounced design elements, Super
Premium Purple sew foam delivers enhanced performance. With a denser
composition—featuring a 1.8 lb density and 75 lb compression—this foam is ideal
for achieving crisp diamonds, bold pleats, and highly detailed stitch patterns.
Available in both 1/8" and 1/2" thicknesses, it is a strong choice
for custom automotive interiors and specialty upholstery where visual impact
matters.
When working
in marine environments or other moisture-prone applications, Blue Marine Grade
sew foam offers added protection. Available in 1/4" and 1/2"
thicknesses, this foam maintains a consistent structure (1.4lb Density, 50lb
Compresion) while incorporating antimicrobial properties to help resist mold
and mildew, as well as being pink stain resistant.
An important note, no matter
the type, all sew foam is shipped compressed for efficiency. It is important to
open the material immediately upon arrival and allow it to expand for
approximately 24 hours before use to ensure optimal performance.
Understanding
the differences between sew foam options allows upholsterers to better match
materials to their specific applications. Whether the goal is cost efficiency,
consistent performance, enhanced definition, or environmental durability, the
right sew foam provides the foundation needed to bring upholstery designs to
life.
