I wasn’t sure what to expect when I ordered these and when they came I couldn’t imagine what was in the box bc they weigh a ton! But these have helped me get into my house (one outside of the front door and one in the garage to step into the house) with ease and safety. They are heavy which is a good thing bc they are sturdy. They have a handle in front so if you only need them for a visiting friend or relative you can carry them to store elsewhere until needed. Mine stay down always and I LOVE THEM. I got the 4 inch so make sure to measure before you order.
