Review on Luxury Massage Seat Cushion: Heat & 8 Node Vibration for Home & Office Chair by Amanda Johnson

I didn't know what to expect from this seat cushion, but since I work at my desk all day I was willing to try anything! At the end of each day there is usually quite severe pain in the lower back and between the shoulders. I added this cushion to my regular work chair (it fitted well) and at the end of the day it reduced my discomfort significantly. Also, wanting to have as much of my back against him as possible seems to make me sit more upright (an added bonus!). It's definitely just vibrating, it doesn't massage by itself, but it relaxes nicely when it's warm. my muscles and possibly maintaining blood flow. I'm glad I bought!
