What's in the box
Solstra Air Seat Cushion, hand pump, storage bag.
Size and materials
45 x 40 cm (17.7 x 15.7 in), about 3 cm (1.2 in) thick when inflated. Holds up to 440 lbs. Waterproof, wear-resistant TPU surface with silicone grip dots on the base and a dual-layer air valve.
How to inflate
Pull the valve, pump it up, lock the ring. About 60-70% full feels right for everyday sitting. On a plane go to about 40-50%, because the air expands at altitude.

Less pressure. More comfort.
Instead of letting one spot take all the pressure, 42 individual air cells help spread your weight across the whole seat.
Add or remove air until it feels right — softer for long flights, firmer for everyday sitting.
Pump it. Sit. Fold it away.
Open the valve on the cushion's edge.
Use the included pump. You choose the firmness.
Secure the valve and enjoy your seat.
Built for long sits
Stay comfortable on long flights without constantly shifting in your seat.
Take pressure off your hips and tailbone during long drives.
Stay comfortable through meetings, workdays, and hours at your desk.
Make hard bleachers and outdoor seats more comfortable.
Why Choose Air
Over Foam?
Built to fix everything foam gets wrong.
