A. Relieve lower back pain: This back support brace contains 4 memory aluminum strips, whose hardness is about four times that of the commonly used PP strips. And 2 steel springs are placed on both sides of the waist to provide relatively strong 360 - degree vertical support for the lower back, prevent excessive muscle rolling, and relieve the pressure on the intervertebral discs. B. 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 different degrees of compression effects. The inner layer is made of velvet fabric, bringing a silky touch similar to a baby's skin, which is quite suitable for wearing as an inner layer. C. Prevent back injuries: This back support brace is equipped with 2 elastic straps, aiming to add extra pressure around the lower back and help prevent back injuries caused by lifting heavy objects, standing or sitting for a long time, doing housework, working, etc. When wearing this brace, it can help relieve problems such as lower back muscle pain, herniated intervertebral discs, sciatica, and scoliosis. D. 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 doing other activities. The 1.5×3.7 wide - size Velcro and 2 elastic straps provide a relatively strong adhesive force. The PVC material usually used in baby clothing is adopted, which is less likely to scratch the skin or damage the clothes. E. Durable and with satisfactory service: The lumbar support uses double - stitching technology and has passed quality control, so it is relatively durable.
