2. A straight narrow staircase
Using a ladder with the letter L will take up a lot of space. Therefore, we recommend that you use a straight narrow staircase like this only. At first glance the design of this narrow staircase is like a bamboo ladder and folding ladder commonly used by builders.
But with wood and polished edges of paint, the results look more modern. This narrow staircase is more suitable for use by adult family members who are still prime because there are no handles or barriers.
