It is important to understand that this and a back brace are two completely different products. You already know that lumbar pillows are designed to be attached to a seat and provide support and enhanced posture. But, a back brace is totally different. This is designed to physically be worn around your waist and is used to stabilize your muscles. What back braces come in handy for is for people who suffer from severe back conditions. They can also help people who have labor-intensive jobs that require heavy loads from their back muscles.
