Looks nice but 550 lbs was probably tested on the sides not the middle because when person of 300 lbs steps in the middle it starts to bend and I heard small noise like crack. We tested it as soon as we got it and I do not recommend it unless you want to step on the side but then what if other side goes up. I got the impression that legs had anti slip pads or something by looking at the picture and description but it’s just plain wood and slides on the tiles like ice. I would not recommend this for seniors at all.
