Consider the Mini 4 Step Value Line Dog Steps for great workmanship at a Value Price. The Value Line dog steps are constructed from OSB and needle punch carpet which is similar to automobile carpeting.
Your are buying less costly materials that do not impact quality or reliability. The carpet is thinner than the standard commercial carpet so the screws will be more visible. However, from a short distance away the Value Line looks very similar to the standard Bear’s Stairs models.
