One thing I found with a weights bench, too, was that since the top of it is foamy/squishy, I had to work on my stabilization even more. You should have seen me when I started on the weights bench - my bf was getting frustrated with me because I was having such a hard time with my balance and he was trying to tell me how to fix it and I couldn't follow his guidance very well. Thankfully, it got better pretty quickly.
I am really impressed at how much my balance has improved since moving to the weights bench. I hated it at first but now sing the praises of high step-ups.
