A stepladder of the folding freestanding type has steps only toward the upper end thereof and has a step deficient region toward the lower end thereof for receiving a smaller stepladder in nesting relation therewith so that the steps of the smaller stepladder provide user access to the steps of the larger stepladder. A nested sequence of such stepladders with all except the smallest one of that sequence being step deficient in a lower region may include several such ladders thereby providing the user with the option of selecting a ladder of a desired height from among several possible heights with the required storage space for the several ladders being the same as the required storage for space for a single ladder of the greatest height. Braces, supports and locking arrangements for fastening each ladder within the step deficient region of the next larger ladder are also disclosed.
A nested sequence of foldable stepladders of varying sizes each of the free-standing variety and with all except the smallest stepladder being step deficient in a region where steps of smaller stepladders make up for that deficiency by providing steps within the step deficient region of the next larger stepladder, each stepladder except the smallest of the sequence including exactly two steps, one near the top thereof and one near the bottom thereof and with each stepladder in the sequence except the largest thereof resting on the bottom step of the next larger stepladder in the sequence.
