Using this shower seat is easy. Just make sure it's properly installed on a suitable wall following local building codes. When you sit on it, keep in mind that it can support up to 360 lbs (163 kg), so don't exceed this weight. If you notice that the seat isn't firmly attached to the wall, the building owner or maintenance staff should take it out of service right away to avoid any risk of injury. For maintenance, since it has a water - resistant seat, you can clean it with a mild soap and water solution. Regularly check the self - locking mechanism and the brackets to ensure they're in good condition.
