1. Relieve lower back pain: This back support brace contains 4 memory aluminum strips, with a hardness about four times that of commonly used PP strips. Additionally, 2 steel springs are placed on both sides of the waist to offer relatively strong 360 - degree vertical support for the lower back, help prevent excessive muscle rolling, and ease the pressure on the intervertebral discs. 2. Can be worn inside: The back support brace uses four - way stretch fabric and 3D knitting technology, which can provide good fit, breathability and comfort, and also has varying degrees of compression effects. The inner layer is made of velvet fabric, giving a silky touch similar to a baby's skin, making it suitable for wearing as an inner layer. 3. Prevent back injuries: This back support brace is equipped with 2 elastic straps, aiming to add additional pressure around the lower back and help prevent back injuries caused by activities such as lifting heavy objects, standing or sitting for long periods, doing housework, or working. When wearing this brace, it may relieve issues such as lower back muscle pain, herniated intervertebral discs, sciatica, and scoliosis. 4. Detailed design: There are 2 silicone anti - slip strips designed on both sides of the waist to help prevent the lumbar support from rolling up when sitting, bending or performing other activities. The 1.5×3.7 wide - size Velcro and 2 elastic straps provide a relatively strong adhesive force. The PVC material commonly used in baby clothing is adopted, which is less likely to scratch the skin or damage the clothes. 5. Durable and with satisfactory service: The lumbar support uses double - stitching technology and has passed quality control, so it is relatively durable.
