  • I have a herniated disc and tried everything — chiropractor twice a month for two years, pain meds, stretching routines, three different seat cushions. Nothing fixed the sitting problem. A friend sent me a link to Reliva™ and I almost didn't click it. I'm so glad I did. The first time I sat on it I felt my tailbone go into the cutout and the back panel hit exactly the right spot on my lower back. I drove for two hours that same day with zero pain. I actually pulled over to check if something was wrong because I couldn't believe it. Two months in — this thing changed my daily life completely.

  • I work from home and sit at my desk from 8am to 6pm most days. My lower back and tailbone were wrecked by 3pm every single day — I'd spend the last two hours shifting around trying to find a position that didn't hurt. I bought Reliva™ mostly because of the 60-day guarantee — figured I had nothing to lose. First week, I stopped shifting. Second week, I forgot I was even sitting on a cushion. It just works. The foam hasn't gone flat either — I've been using it every day for four months. I bought a second one for my car because I wasn't going to go back to sitting without it on long drives.

  • My mom has sciatica and I spent months trying to find something that would actually help her. She couldn't sit through church, couldn't sit at dinner, couldn't take a car ride longer than 20 minutes without pain. I ordered Reliva™ for her as a Christmas gift after reading through what felt like a hundred reviews. She called me a week after Christmas almost in tears — she said she sat through the whole service and then dinner that same day. First time in over a year. I've since bought one for myself and one for my dad. If you have someone in your life who is always in back pain and you want to actually help them — this is it.

Our Commitment To Every Driver

After years of customer feedback, design testing, and working with doctors and chiropractors, we built Reliva™ for one specific person — the driver who has already tried other cushions and is still in pain.

We know what it feels like to finish a long drive and barely be able to get out of the car. That's why Reliva™ uses an integrated one-piece L-shape design that keeps your tailbone off the seat and your lower back supported — at the same time, every single time you sit down.

Your pain-free drive is our goal. And we back it with a full 60-day money-back guarantee.

Built on real orthopedic support principles not just soft foam.

The World’s #1 Orthopedic Seat Cushion for Everyday Comfort

What is Reliva™?

Reliva™ is a one-piece orthopedic seat cushion built for people who sit for hours every day — at a desk, behind a wheel, or in a wheelchair.

It uses an L-shaped design that permanently connects the seat pad and the lumbar back panel. Because they are one piece, they never drift apart. The tailbone cut-out means your coccyx never makes contact with the seat. And OrthoFlex™ foam holds its exact shape through months of daily use — it does not bottom out like regular foam.

You just sit down. The cushion does the rest.

Why is Reliva™ the best way to stop sitting pain?

How Reliva™ works

Three things happen the second you sit down — all at once, without any effort from you.

1- Your tailbone stops touching the seat
The coccyx cut-out suspends your tailbone in open air. No contact means no pressure. That is why the pain stops so fast.

2- Your lower back gets pushed into the right shape
The integrated lumbar panel meets your lower back and holds it in its natural curve. You sit up straighter without trying. Neck and shoulder tension drops too.

3- Your weight spreads out — instead of pressing down on one spot
OrthoFlex™ foam maps to your hips and thighs and spreads your weight evenly. No more pressure building on your sciatic nerve or hip joints during long sits.

Frequently asked questions

Will it fit my car seat or office chair?

Yes. Reliva™ is 17.3 inches wide and 16.5 inches deep. It fits most standard car seats, office chairs, dining chairs, and wheelchairs. It comes in Large and Extra Large so you can pick the right fit for your body.

Will the foam go flat like every other cushion I have tried?

No. OrthoFlex™ Adaptive Foam is specifically made to hold its shape under daily use for 9+ months. It uses slow-rebound memory foam — not the cheap foam that bottoms out in a few weeks. This is the most common thing people notice when they compare it to other cushions.

It looks firm. Will it actually be comfortable?

The firmness is exactly what makes it work. It needs to hold your spine in alignment — a soft, squishy cushion cannot do that. Most people feel the difference within the first few sits. Think firm mattress, not hard floor.

Will it slide around in my car or chair?

No. The rubberized non-slip base grips the seat surface. The adjustable strap wraps around the chair back. It stays in exactly the right position all day — no readjusting.

What if it doesn't work for me?

You are covered by a 60-day money-back guarantee. Try it for two full months. If you don't feel a real difference, get a full refund. No hoops.

Can more than one person use it?

Yes. The cover is removable and machine-washable. It is easy to keep fresh for shared household use. Many families buy one for the car and one for the home office.

  • Pain-free after 18 months of trying everything

    ⭐⭐⭐⭐⭐
    I have sciatica and I honestly stopped believing anything would help. I have tried donut cushions, lumbar pillows, gel pads — all of them. This one is different. The first week I noticed I was not shifting in my seat every 10 minutes. By week two the end-of-day tailbone pain was basically gone. I ordered a second one for my car.

  • My lower back was screaming every day. Not anymore.

    ⭐⭐⭐⭐⭐
    I drive a truck for work. My back was wrecked by mile 100 every single day. I was skeptical about a cushion fixing that — but I took a chance. I drove 3 hours last week and felt nothing. No burning, no stiffness when I got out. This thing paid for itself on the first long run.

    Marcus T. — long-haul driver

  • I bought it for my mom. She cried when she called me.

    ⭐⭐⭐⭐⭐
    Mom has sciatica and could not sit on hard chairs for more than 10 minutes. I got her this for Christmas because I had run out of ideas. She called me a week later almost in tears. She sat through the whole church service and dinner that same day. First time in over a year. Best thing I have ever bought her.
