Play yard changers?

Maybee • 👶 💙 = 2018, 👶 😇 x2 = 2020, 😇 x 2 = 2021, 👶🌈=?

Help! FTM looking for advice - was thinking of setting up a play yard on my main floor for baby during the day and using the play yard changer piece as a change station (rather than climbing stairs every time baby has to be changed).

Some of them look smaller than others area-wise , is this a reasonable plan, or are they small and only last a month or two (and then I’d have to find something else)?

Advice please! Thanks 💜
