RELAXOBAK Original Orthopedic Sacroiliac Seat (Black, 2-pk) Tailbone Shield and Pelvis Stabilizer - Keeps Spine in Alignment and Supports Coccyx, Back, and Hips, Holds up to 300lbs

It's like a miracle. This device has literally saved my husband's job. He is a truck driver and on a new job since a few months, driving a semi with hard seats, so after just three hours of driving, he is in pain, and was thinking he would have to quit again, and find a new line of work.Having had several back injuries, he previously quit a good driving job because he had to offload product, which was killing his back.After a year off the job--doing light duty style work, and undergoing weekly therapy--he felt good, and took to the road again, only to discover that the hard seat was again causing pressure and pain to his spine.It must have been Divine Providence that guided me to see this product, while looking for an accupressure mat for my stepson.My husband used the Relaxobak for the first time today, and he called me three times during his ten hour shift and commute to say how great his back felt--the whole day!! This is amazing, as I said, and I hope it continues to help.My husband came home refreshed, happy and pain-free.I am so happy, I could cry!!

Genius live in simplicity. RelaxoBak is quite simply the greatest asset for one's back ever devised by man. It offers complete back and tailbone support I've ever experienced. My back and tailbone no longer hurt. I no longer feel pain from sitting. My work involves trading the financial markets. I sit for long periods of time. When I have combined the dual effort of getting up once an hour for 2-4 minutes of exercise and using Relaxoback while I sit, it has given me complete relief for back pain. I no longer feel pain and it no longer is a distraction for me. I can give full concentration to my work. Thanks for everything your brilliant product has given me! It is a Godsend.

Comfy & help on my super comfy couch. I love kicking back on my couch and it aggrevates my back from time to time. Remember to position it correctly (it is labeled on the seat) and it does prompt you to sit with your hips forward a little. Have also used it in the car for long rides. Could still use seat warmers with it. Not heavy, sturdy but not rigid, comfortable & allows your legs and sides to "spill over" and doesn't hurt or feel uncomfortable so anyone of any width can use this.

I have no idea how this is supposed to work. There are no instructions with the product and nothing online. They have multiple commercials for the product on their website but not one instructional video. I have tried using it multiple ways over 4 or 5 months and found it to be uncomfortable. It's hard plastic so my butt gets sore. (I'm slim but I have a bigger butt so there's a reasonable amount of "natural padding" but it still hurts after and hour or two. It's slippery so you tend to slide around and there's no instructions about how you're supposed to sit in it. When it's in the car, I find that I can't relax and my back hurts after a short ride. I think I'm just going back to a good ole cushion.

I bought a two pack and was going to give one to my son and ended up keeping it. I keep it on my couch where I sit and it has greatly reduced my back pain. I didn’t intend to keep it there, but it made that much of a difference that I will keep this little eye-sore under a towel on the couch now.

I can't believe that they work. I have a bad back and get a spinal epidural shot every two months. If I sit on a hard surface and put pressure on my lower spine I will be taking a pain pill within an hour. I have tried several types of cushions to no avail. When I saw these on Amazon and the low price plus past reviews I ordered two. When they came And I looked at them I laughed thinking I would stack them with my past cushion failures. These are not a cushion but a hard plastic and look cheap. After a few days I used them and I was astonished...they work and I can't do without them.

It is not as comfortable as I expected it to be. It is too slippery. When I sit on the pad, there is a need to adjust it and be careful that it is centered because I feel that it will move before I am settled down, especially when I am driving. I have not had it long enough to determine if it is helping my lower back. I am still using it. It is not causing me any pain. I will give you more in put as time goes by. Thank You.

This device does not appear to do much for me. At best, it stops me from sinking in to soft cushions of my chair. The plastic seems to lose its forms and firmness after a few days to the point where it bends all over and offers no support at all.
