The seat that stops your pelvis rolling back so your lower back finally gets a rest.
Built with car-seat engineering, not furniture foam. One piece that fits any chair you already own.
- Holds your pelvis level, so it can't roll back
- One piece. Nothing slides or shifts
- Nothing to take, nothing to adjust. You sit on it.
I work from home and sit for more than 8 hours a day. I'd tried everything. This cushion is the only thing that lets me sit all day comfortably.

Fits most chairs with a backrest. Office, dining, car.
You've tried the cushion. It helped for a week.



Then the shifting came back. The stiffness. The groan when you stand up.
Softer cushions, lumbar pillows, a better chair. They all help for a while, then stop.
That's because none of them fix what happens the moment you sit down.
It was never your posture. It's your pelvis rolling back.
Your pelvis rolls back. Your back pays for it.



On a flat or soft seat, your pelvis tips backwards. Your lower back slumps into a C, and your weight lands on your tailbone. Hours of that is the ache.
Car seats solved this years ago. They're not softer. They're shaped so your pelvis can't tip. That's why you can drive for hours and get out fine.
The PostureForm is that shape, for any chair.
One piece, two jobs:
- Pelvic Alignment. The cradle holds your pelvis level, so it can't roll back.
- Tailbone Float. An open channel lifts your tailbone off the seat.
- The back is part of the seat, so there's no gap and nothing slides apart.
After an hour, you're still sitting the way you sat down.
Why the others stop working
Each one makes the seat softer. None of them hold the pelvis.
They make the seat softer. None of them stop your pelvis rolling back.
Any chair. Ten seconds.



What it does that a cushion doesn't
The Car-Seat Cradle

- Lifts your tailbone off the seat
- One piece, nothing slides apart
- Grip base stays put
- Dense foam that holds its shape
- After an hour: still where you started
Foam, gel, donut, lumbar pillow
- Pelvis rolls back into a slump
- Tailbone pressed into the seat
- Two pieces drift apart
- Creeps forward during the day
- Soft foam that flattens
- After an hour: shuffle and re-adjust
Questions before you order
Will it fit my chair?
Most chairs with a backrest: office, dining, kitchen, firm armchairs and car seats. It's 42 cm wide, 41 cm deep. Not for deep soft sofas or backless stools.
Can I use it in the car?
Yes. It sits on most car seats and the back stays below the headrest.
I've had back pain for years. Will this help?
Whatever the cause, a rolled pelvis loads it. Holding the pelvis level takes that load off. That's all we claim.
Is it firm or soft?
Firm enough to hold you, soft enough to sit on all day. Dense foam, not a pillow.
Does it slide?
No. The base is a silicone grip surface.
Will people notice it?
It looks like part of the chair.
Can I wash it?
The cover zips off and goes in the wash.
What if it doesn't work for me?

I spent eighteen months and over $3,000 on my back. The fix was the shape of what I sit on. I can't promise what it will do for you. I can take the risk off you.
