This step stool features a simple but ingenious safety design:  The guard rail can be installed on the left or right side and requires the child to turn safely toward the steps  -- not backwards like other models -- to look for the hand rail. The steps include non-slip treads for increased safety. Constructed in beautiful, durable birch plywood in safe, non-toxic natural UV finish that won't fade and withstands rigorous use. Made in the USA.  GreenGuard™ Gold certified.  Lifetime Warranty.
