At first, it was easy to ignore.

David Miller, 47, works at a desk for most of his day. His mornings were usually fine. But sometime after lunch, the routine changed.

He'd lean left. Then right. Cross one leg. Uncross it. Slide toward the edge of the chair. Stand up for a minute, sit back down, and repeat.

He tried to solve it the obvious way.

Then came the appointment he had been putting off.

After the discomfort became difficult to keep ignoring, David booked an appointment with a physical therapist.

He went in hoping for a quick fix. He left thinking about something much more basic: how much of his day was spent sitting in essentially the same position.

The appointment didn't end with a miracle solution. It changed the question: move, adjust, change position — stop expecting one fixed setup to feel right for eight straight hours.

But one thing still bothered him about the cushions he'd tried.

They all decided the firmness for him. Too firm? That was the cushion. Too soft? Same problem.

That's what made an air-cell design interesting.

Not because air is magic, but because it introduces something a solid piece of foam can't offer in the same way: you can change the feel.

How is it different from the usual seat pad?
