The Spark Series Vertical Ladder is a simple metal climber with more useful features than its name would suggest. The steps are each curved inward, although the steps are still straight and parallel to the ground, which makes them stable and easy to balance on. The curved steps also help make it easier to use the outer bars as handrails. The straightforward nature of this design makes it easy for children of all ages to immediately recognize and use. The ladder is spaced a few inches away from the edge of the platform, which makes it easier for children to enter and exit it. The metal materials used in this climber are commercial grade galvanized steel with a powder coating of baked-on paint. The paint is available in a wide spectrum of customizable color options which can be chosen before completing your order.
