I love that this ramp folds in half and has a carrying handle. Much lighter than I expected. It does bounce a little when walked on, but it is sturdy and supports up to 800 pounds, so far between my husband, son, and wheelchair almost 600 pounds was supported easily. The sides have an edge barrier with a reflective security yellow and black strip the entire length on both sides. The edge barrier will keep the wheelchair from falling off the ramp. It gives plenty of space to push a wheelchair up the ramp. You need to balance the wheelchair between the ramps as you would using any ramp. There is a lip at the top to rest on a flat surface but the bottom doesn't have a lip which has not affected its use. The nonslip surface material gives plenty of friction. The step where I am using this is only one step that is about 6 inches from the ground so the ramp isn't at a steep angle but you could use this at a steeper angle.
