The Pebbl is the first physical product developed by Soul Sparks Collective.

The Pebbl is a posture-promoting floor chair designed to comfortably bring you in contact with your surroundings and allow you to focus on the moment, while sitting comfortably in various meditation poses.

Pump worked with Soul Sparks Collective and their design partner to design, prototype, and evaluate the Pebbl chair. The key features include a hinge that allows the chair to stay open comfortably while providing good back support and strength (when people lean back). The chair offers easily removable and washable cushions. And it is portable, allowing users to bring their Pebbl with them and practice mindfulness anywhere.

Pump helped engineer a solution that met these requirements, while also delivering a rugged and durable solution. We worked directly with the manufacturer to ease fabrication and assembly while also optimizing the cost to build.
