New Stairs for an Intex pool

I am currently in the market for a sturdier set of stairs for my above ground intex pool. I have an elderly mother who has trouble using the ones that come with it. Does anyone have any suggestions as to what would be a good alternative and where to buy it?

Thanks!

Not sure how big your pool is our how appropriate these would be for your pool, but google "wedding cake steps." See if that is something that you might could use.
