ERGO21 Seat Cushion Reviews

I purchased this seat cushion for my truck. We are full-time RVers and travel days can get pretty long. I’ve tried several cushions and it was turning into a Goldilocks and the Three Bears situation… “this one’s too thick,” or “this one’s too soft,” or “this one cuts off the circulation in my legs at the front of the seat.” This seat cushion has addressed all those issues and meets my needs perfectly.

If you struggle to sit in a car or at a desk due to sciatica or low back pain, this cushion is for you. As an Uber driver with over 2,200 rides, this product is simply the best of the best for assuring positive blood flow over the course of a long night at the wheel.

Love this cushion in my car. I drive a 2015 Hyundai Sonata and I’ve always felt that my lower back was being unsupported with the regular seating. I would always be adjusting every few weeks to fix my posture but was never satisfied in my driving position. I got one of these and put it on my car seat and wow. I feel like I’m sitting on a cloud. It supports my lower tail bone and my butt perfectly. It feels that cars should feel this way naturally but they don’t.

Got this and the lumbar cushion for my wife’s car. She likes it. Plan to get another set for my mother’s car.

I really like this seat cushion, after reading reviews ; I ordered , not disappointed at all ….most seat cushions make me sweat after seating awhile; can be embarrassing to say the least …..I have sciatica and Spinal stenosis & was operated on for herniated discs …..so I have problems with hard bottom chairs or too soft , Helps me when driving any distance …very comfortable …..I sent for a 2nd set , now have one set for car , one for bottom for my leather recliner …..

Best Review for Our Products

This cushion got rid of my pressure sores!

After a motorcycle stunt gone wrong, I ended up in a wheelchair for the last 50 years. I have tried all kinds of gel and air cushions. The gel cushions got hard after a few hours of sitting and the air cushions that I got provided good relief but there were always some pressure points from the chambers. Also, the cushions lose air after a few weeks and unless I pump and test the air regularly, I end up uneven. I read about the Ergo21’s LiquiCell membranes and was intrigued. I got their Ergo21 Sports/Wheelchair cushion a couple of years ago and after 8 or 10 days my pressure sores went away. The cushion had good quality foam that gave proper support without compressing too much. The fabric cover is a stretch type material that does not pinch my skin. I got this Ergo21 Travel cushion for my other smaller portable wheelchair, and it provided the same level of comfort with no pressure points. And this travel cushion works in my car and takes the numbness away without adding any height. Highly recommended. Thank You Ergo21

ERGO21 Office and Cars Seat Cushion Reviews

I love this seat cushion. I have been trying out different seat cushions to alleviate the pain in my back and legs. I’ve tried a memory foam cushion, and another highly rated ergonomic cushion – both were able to reduce the pain only slightly. This is the third type of cushion I tried. Within a day or two I was no longer in pain while driving or sitting.I ordered another one soon after. Great!

Jamie

Thanks for the feedback! We looked at 19 different foams, then  narrowed it down to seven. We chose this high resilience foam, that doesn’t bottom out and at the the same time offers support. The layer of LiquiCell prevents hot spots which prevents shifting, thereby keeping the  spine and neck aligned to give you long term pain free comfort. Feel free to all on us anytime we can be of assistance.
