I was surprised to find a commode with all of these features at this price point, and I wondered if it would be stable. This item exceeded my expectations-- it feels very stable during transfers and when I'm sitting on it, there's plenty of room, the arms flip up and down easily, and it's easy to install or remove the bucket even with a liner. Assembly was straightforward but I recommend keeping all of the fasteners somewhat loose until all of the parts have been put together, and have something long and narrow (perhaps a phillips screwdriver, chisel, or awl) to use as a drift to align the holes. When I put it together, I tightened up the four screws in the frame early in the process. When I went to install the crossbar the holes for the C-clips were misaligned by 2-3in... once I loosened everything up again I was able to use an awl to align the holes, then install the clips, and finally retighten the screws.
