Most back pain relief products only squeeze your back. Some, like inversion tables, or other hanging or rack products, provide too much decompression, are bulky or require multiple visits to medical providers, and only provide temporary relief. The MerryBack® is so different, we obtained a US Patent on the way it works. Its ergonomic design provides just the right amount of gentle decompression for long lasting relief, not just while you're wearing it. And... its portable, light weight and can be worn under your clothing! The MerryBack® is a three-in-one spinal decompression system that leverages your body's own architecture to transfer the weight of your upper body to your hips and off of your lower back where all that pain is, creating a lower back stretch that alleviates back pain while you sit or stand.
