According to the Mayo Clinic, it is a good idea for older people to sit in a recliner for a few hours each day. Recliners are also good for old people with back pain because they can relax while being massaged. Some recliners are designed to help you get up and down more easily, and they are also designed to be more comfortable than straight chairs or sofas. However, it is important for people to sit up at a 45-degree angle and to alternate between sitting up and lying down in order to protect their bodies and prevent blood clots.
