The two main features in the structure of the My Back Booster Seat are:
1. Back support – the lumbar support in the lower back ensures that your back is fully supported
2. Lumbar Support – is the holy grail feature of the My Back Booster Seat. It fits your lumbar spine like a glove fits your hand. You have to try it to believe it. Your back will definitely thank you for finally providing it with the needed support.
