Support that doesn't give out.
High-density memory foam in an ergonomic U-shape. Made by someone who got tired of cushions that didn't work, and built one that does.
Ergonomic U-shape
An open tailbone cutout takes pressure off.
High-density foam
Holds its shape instead of going flat.
Non-slip base
Stays put on car and office seats.
Washable cover
Breathable mesh that unzips and machine washes.
I couldn't find a cushion that held up. So I made one.
Years of buying pillows that went flat taught me one thing: soft isn't support. Sitvana is the fix I wish I'd had.
