Resit’s launched a sensor pad that turns your chair into a posture tracking system

The modern workday means most people spend eight-plus hours in an office chair with no real information about what that’s doing to their body. How you sit affects everything from back and joint health to energy, breathing, and long-term movement quality. But no amount of time in the gym fully offsets eight hours of poor positioning.

The Resit Altair is a sensor pad that retrofits onto your existing office chair to track how you’re actually sitting in real time, turning that data into feedback designed to change behavior over time.

How it works

The pad captures posture type, pressure distribution, weight balance, and movement frequency throughout the day. The focus isn’t on holding a rigid upright position, but on variability, meaning whether you’re shifting enough to avoid locking into one place for too long.

When you’ve held a suboptimal posture for more than ten minutes, the pad delivers a haptic nudge subtle enough not to break focus. Then, session summaries in the app surface specific patterns, like consistent leftward lean or low movement during long stretches, rather than generic advice.

All of it feeds into a Sitting Score (0–100) built from three inputs: how much you move, how long you spend in poor positions, and how evenly your weight is distributed.

Resit’s sleep score captures how long you stay in sub-optimal postures.

“Over time, this turns posture from something abstract into something measurable and trainable,” says Alessandro Taula, Resit’s founder. “Real-time nudges drive immediate correction, while scoring and analytics drive long-term improvement. That’s how the loop closes: not just feedback, but continuous learning on your own sitting behavior.”

Altair is compatible with most major chair brands, including Herman Miller, Steelcase, Haworth, IKEA, and Amazon Basics.

Where to get it
