The step ladder with the armrest comprises two front legs, two rear legs, at least one rung, and an armrest. The armrest comprises a lateral tube, two vertical tubes, and a lock mechanism. The lateral tube is connected to top ends of the two vertical tubes, and the two vertical tubes are respectively and movably disposed in the two front legs. The lock mechanism comprises a link rod disposed in the lateral tube, two push rods, two pins, two pin springs, and two push rod springs respectively disposed in the two vertical tubes. The two push rod springs drive the two push rods to move upward to abut the link rod. The two pin springs drive the two pins to move laterally out of the through holes the two vertical tubes to be disposed in two of the plurality of positioning holes.

A pool ladder may have a first and second leg extension, each having a generally continuous profile; a first tread may comprise first and second through-holes, the first through-hole being sized to slidingly receive the generally continuous profile of the first leg extension, and the second through-hole being sized to slidingly receive the generally continuous profile of the second leg extension; and a first and second tread support. The first tread support may be engaged at a tread location on the first leg extension and may be separate from the first leg extension. The second tread support may be engaged at a tread location on the second leg extension and may be separate from the second leg extension. Each of the first and second tread supports may protrude from the respective leg extension a sufficient amount to prevent the first and second through-holes from sliding past the tread locations.

A ladder is provided having a base section and a fly section slidably coupled with the base section. The base section includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. The fly section includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. The various rungs may be coupled with their associated rails in an offset relationship such that they are not centered along a longitudinal center axis line of the rails. A rung lock device may be used which includes an arm pivotally coupled with the base section and configured to selectively engage various rungs of the second plurality of rungs to maintain the fly section in a desired position relative to the base section.
