OPTP The Original McKenzie Signature SuperRoll Lumbar Support - Low Back Support for Office Chairs and Car Seats

This one is perfect! Very comfortable! Customer service is beyond excellent! Very happy with purchase! Thank you!

長距離ドライバーです。 前は特に長時間乗った後は腰が本当に辛かった。そんな時理学療法士の先生から紹介してもらい購入。 長時間運転した後の腰のつらさがかなり楽になり、特に嬉しかったのが、車の乗り降りが本当にスムーズに。毎日使うものは妥協しないほうがいいなと実感。ずっと使ってもへたらない。 長く使えるので腰痛を持つ人にかなりおすすめ。

It is very helpful. You can drive as much as you want without anything pain or stress

通っていた整体で使ってみてとても良かったので、購入した。 とても腰への負担が減り、姿勢よく座れておすすめ。

My daughter is a physical therapist, and the McKenzie method is taught in physical therapy school. This back support was designed by the physical therapist McKenzie. After using the support in my office chair and in the car with leather seats on a long road trip, I had to discontinue use. Instead of alleviating back pain, it made my pain worse. The firmness is much too hard (and I think there is an even firmer version). The strap does not help keep the cushion in place really. You still have to constantly adjust the cushion if you move to make sure it is placed in the proper area of your back. My mother has different back issues than I do, so I gave the support to her to try. Since she is older, her skin is thinner with little fat underneath, and the cushion left a red imprint on her back. I am not sure the shape is a good fit for most backs either. The biggest problem is that the cushion is much too firm/hard.
