Installing a staircase can be daunting task. Fortunately for you Ambient has got you covered with all the components you need. Stair risers (also called up boards) are the vertical sections of the stair case. While it isn't necessary to match the risers to the treads (we also carry white risers for contrast) it can be a wonderful finishing touch on your project. Please be sure and look over the dimensions in the images above or feel free to give us a call if you have any concerns.
