Review on Premium Magnetic Bubble Massaging Seat Cushion For Car, Office, And Home - Stress-Free Comfort All Day Long by Jamal Yang

The one elastic strap that's supposed to hold it in place on your seat was too small to fit around my seat well. It moved around every time I would get out. The strap snapped off within a day of use. I used a cheap elastic strap from the hardware store to secure the mat where the backrest meets the seat. It seems to be holding well now. Doesn't move around as much. The cushion itself does its job. I can definitely tell a difference while driving long distances. I make deliveries in my car so I spend a lot of time on the road. This mat does a good job of giving your muscles a little change of pace. Just wish the placement strap was better designed.
