Jute webbing vs S-springs: why we chose the old way
S-springs are cheaper and faster to install. They're also why your last sofa sagged.
Why sofas sag
A sofa's seat base is the single biggest determinant of how it ages. Three common approaches:
- S-springs (sinuous springs): steel zigzag wires. Cheap, quick. Sag in 3–5 years as the steel fatigues.
- Pocket springs: small pocketed coils. Comfortable but hard to re-tension.
- Jute webbing: woven jute strips interlaced across the frame. Slow to install. Lasts 15+ years with free periodic re-stretching.
Why jute
Every jute strap can be individually re-tensioned without dismantling the sofa. When one strap loosens over years, we pop the dust cover, pull the strap tight with a tensioner, and staple it. Twenty minutes. Zero cost.
That's why we offer lifetime free webbing re-tensioning on every setti we build — the structure makes it possible.
