Abstract
A pool stair assembly includes step members having riser panels and tread panels, the step members joined together to form a multi-step structure. In illustrative embodiments, a spacer is located between a connection flange of a first step member and a riser panel of a second step member to form a channel therebetween, with one or more detents extending into the channel. A swimming pool liner includes locking tabs at predetermined locations that correspond to the channel, the locking tabs insertable into the channel to secure the liner to the step members. When the locking tab is inserted, a lip of the locking tab is compressed against the detent to move the locking tab past the detent when sufficient downward force is applied. The lip naturally biases back to its original position after passing the detent, preventing removal of the locking tab from the channel.
