## Customer Reviews

### ⭐⭐⭐⭐⭐ High Quality Foam Block
*by S***U on June 10, 2025*

If you practice any kind of posture alignment therapy and want a really cohesive exercise session this foam block is the ONE thing you need to really accomplish the pain relief and strengthening that comes with static (lying down) exercises.It's so great to not have to use a chair or other piece of furniture which can be cumbersome and distracting while doing your routine.

### ⭐⭐⭐⭐⭐ Just perfect!
*by S***M on March 10, 2025*

I do the E-cises that Pete Egoscue described in his book pain free. This bl9ck is perfect for doing the exercises. The block arrived on time and was well packed. I highly recommend it.

### ⭐⭐⭐⭐⭐ Quality item
*by K***B on January 1, 2025*

We try and buy quality products as opposed to the cheaper disposable items that are so readily available and this item has met and even exceeded our expectations. We purchased this for use with other Pain Free At Sea exercise equipment. The company owner Lisa has quickly answered our questions in a friendly and helpful manner. I have not received any form of compensation to write this review and endorse Lisa and her company without reservation. Thank you.
