The Forma collection
Forma Stacking Armless Dining Chair
About the design
Features
- Frame handcrafted of extruded aluminum in our workshop
- Superior quality powder coating applied for weather resistance
- Batyline mesh sling suspension adds comfort to the sit and overall functionality. Batyline mesh is easy to clean, as well as resistant to fading, stretching and stains.
- Stackable Design for Easy Storage - Thoughtfully engineered with special leg detailing, this chair stacks effortlessly—perfect for maximizing space when not in use.
- Our custom outdoor covers are strongly recommended as an extra layer of protection against the elements and natural aging
- If the furniture will remain covered and not used frequently, we recommend periodically taking off the covers to allow moisture and humidity to dissipate from inside allowing the furniture to breathe. This helps reduce trapped humidity if the furniture is not regularly used.
