This polypropylene fabric is often referred to as "synthetic sagless" because it's a synthetic material that can take the place of traditional sagless jute burlap and similar fabrics. It offers high strength and low stretch for no-spring inside backs and spring cover applications.
Springtex is available in 3 oz, 4 oz, and 5 oz constructions. While we recommend the use of strip webbing with the 3 oz construction, strip webbing is not required when using the heavier constructions. Springtex is available in a wide variety of standard widths.
