From 2019 to 2025, my MRIs told the same story: a herniated disc at L4–L5, pressing on the nerve. Sitting was the hardest part of every day. These are the habits that made it more manageable for me.
I'm not a doctor and this isn't medical advice. Every back is different. Your doctor or physical therapist should guide your treatment.
At the desk
- Get up every 30–45 minutes. Even a two-minute walk to refill water helped more than any chair adjustment.
- Set the chair so your knees are about level with your hips and your feet are flat on the floor.
- Sit all the way back so the backrest actually supports your lower back.
- Use a firm cushion, not a soft one. Soft cushions flattened under me within minutes. Firm, high-density foam held up.
In the car
- Move the seat closer so you're not reaching for the wheel and pedals.
- Fill the gap in bucket seats. Many car seats tilt you backward and down. A firm cushion levels you out.
- Stop every hour or so on long drives, even for a few minutes.
On flights
- Book an aisle seat so you can stand up without asking anyone.
- Bring your own cushion. Airline seats are thin and slope backward. A light cushion that fits in a carry-on makes a real difference.
- Stand and stretch whenever the seatbelt sign is off.
At the dinner table
This one surprised me. Hard dining chairs were sometimes worse than the office. Bringing a cushion to family dinners meant I could actually be present instead of counting the minutes.
FAQ
Is sitting bad for a herniated disc?
Long, uninterrupted sitting was the hardest thing for me. Breaking it up and having better support helped. Ask your doctor what's right for your specific case.
What kind of cushion helps with a herniated disc?
For me it was a firm, U-shaped memory foam cushion with a tailbone cutout. Soft cushions never held up. A cushion is for comfort, not treatment.
Should I use a lumbar pillow or a seat cushion?
They do different jobs. A lumbar pillow supports the curve of your lower back, and a seat cushion supports what you're sitting on. Some people use both.
Those six years are why I made the Sitvana Seat Cushion: firm, ergonomic and light enough to bring everywhere. You can see my actual scans and story here.
