CalCore Lumbar Back Stretcher with Acupressure Nubs for PT and Lower Back Relief

No booklet, however it works ok, just got to use ones imagination a bit. Found sitting on edge of bed, feet on floor, allows one to rock back and forth a bit.

I hardly ever give any Reviews.....but I thought this Product deserved one because it has helped make my back feel pretty good. It did feel a little uncomfortable when I first tried it. I could only do it for about 10 minutes at first.....but as my Lower Back started feeling less sensitive I could do it for up to 30 minutes. You don't want to stay in one position no longer than 5 minutes. Try building a Pattern where you make different moves. Then after using it try doing some Stretches while still on the floor. I do my own technique called Wag Your Dog Tail move. Act like you are Dog and Wagging your Tail while on all Four / Hands and Knees . Then Stretch your back by trying to make a Cat Screech Movement....LOL..... This is the best I can try to explain....LOL ......... Now if you have a Major Spine Problem I recommend to be very careful on doing this. It might not be for you....... Hope this helps........ I got mine for $15.... Great Price......Worth the money and I can tell it will last a long time without wearing out.

Very uncomfortable AND the least they could send is a users manual. My daughter tried it and said "OUCH".......

This product works great. The people who gave it low reviews obviously did not know what they were buying. It is firm yes, but it's supposed to be. It works like acupressure. If it hurts it means it is working out the knots in your back. It is a stiff foam but it is not so hard that you cannot lay on it. I sit on it, stand on it and use it as a back rest. It works great. I have had back problems for numerous years and it does work well. Unless you are a tall person, I suggest you getting one that is lower in inches. I think this one was 3". I m 5'3" and I think 2" would have been better for me for my back. Other than that, I still use it and it works great.

It did not help me.... also I think they could make it smooth and it would work the same.

I really didn't think it would work, to my surprise it does. When you lay on it and relax, really relax, you can feel it doing its job. However you will feel intense pressure and pain until your back adjusts to it. Remember to relax, its only temporary.

It really helps you stretch your back without pain very comfortable.

terribly uncomfortable - I had to return it
