Airline seats are tiny, narrow, and rigid. They force your body into a position where all the pressure piles onto your tailbone and lower spine. After an hour, you start to feel the dull ache. After five, the pain radiates down your back and legs like fire. That’s the torture most flyers accept as ‘normal. The Sondur cushion uses a patented Air Cell design that absorbs pressure and redistributes your weight. It keeps your spine aligned so instead of feeling like your bones are grinding into metal, you feel supported. Like you’re sitting on a cloud that soothes your back and butt.
