The cushion combo includes the seat and the lumbar support backrest. This means that there are two designs to address. The seat cushion has a U-shaped design which is recommended by orthopedic surgeons in helping sciatica, coccyx, and tailbone pain. The sciatic nerve pain and sciatica will be tremendously helped also by the design of the back support, which is well designed for an office chair.
The contoured shape of the lumbar support supports your spinal health, as it keeps your spine from slouching, promoting better posture. The better posture will decrease nerve pain, as your body will become accustomed to having tendons in the natural order, with shoulders back and hips set, decreasing sciatica nerve pain.
There are non-slip backsides to the seat, and adjustable straps for the back cushion, making it easy for office chair, office environment, wheelchair, or recliner access. The one possible downside to this product is that for very large people, the seat can feel a bit small. For normal-sized people who are not very overweight, the seat should fit perfectly according to our research.
