Fix Your Posture Without Trying.
Most chairs force your spine to compress, putting all your weight directly onto your tailbone. Our system integrates a teardrop footrest to actively take the pressure off your thighs and lower lumbar.
The CushionCave™ ergonomic U-shaped design suspends your tailbone, shifting the pressure to your thighs and hips for all-day relief.
