ComfiLife Premium Comfort Seat Cushion Reviews

A customer insisted, "You WON'T be disappointed. This product is a lifesaver. Short Review: I have been using this product daily for almost three months. It has rid of all my tail-bone pain. Don't think twice - buy this product. You won't regret it."

"FINALLY SOME RELIEF FOR MY SCIATICA!! I have suffered for over 10 years with chronic back pain and excruciating sciatica. The back pain is constant, and the sciatica comes and goes. Sometimes just for a few hours, and sometimes for weeks or months. I've tried many different pillows over they years, and this is by far the best one for some relief while sitting. I am currently using this one on my computer chair, but have used it on my recliner, as well, as the sciatica doesn't care how comfortable the chair is. They are all the same with sciatica. This really has helped me, and I am thinking about purchasing an additional one for my car," a fan of the cushion shared.

Another said, "WORTH EVERY PENNY! Long story short: This product is keeping me from having to make a weekly chiropractor appointment."

An Amazon shopper said, "I bought this after reading the reviews and after trying several others that I sent back. I could not get along without it. I fell in December and fractured my pelvis. The only way i could be in any way comfortable was lying in an adjustable bed. That gets old! After I got the ComfiLife Comfort Seat Cushion, I got some of my life back! I can go out to eat with friends, watch television sitting up and even play on my computer. I have a friend who suffered the same accident several years ago & after she tried my cushion at lunch one day, she ordered two; one for the house & one for the car. She has recommended it to several friends with different conditions that make sitting painful."

"Finally, Relief From Pain When You Sit All Day. I use this on different types of chairs- not just office chairs, but even dining room or table chairs- as long as the chair is wide enough, the cushion is great. The cushion doesn't flatten out, but supports your seat all day... This is the best cushion so far that I've found for sitting pain free, so I have to give it 5 STARS," a customer wrote.

And this review really sums it up: "I have suffered for over 10 years with chronic back pain and excruciating sciatica. The back pain is constant, and the sciatica comes and goes. Sometimes just for a few hours, and sometimes for weeks or months. I've tried many different pillows over the years, and this is by far the best one for some relief while sitting.
