We bought two sisalpoles that we installed vertically, to create a decent climb for our cats. I personally don't like the toggle fixings that come with the furniture because I find them difficult to set when you've got multiple holes to do. Found that M5 cavity anchors (rated for 20-25kg each) were easier to set and better to work with.
The sisalpole is big, sturdy and the cats absolutely love climbing them. We've had other things from RHR before and they last a lot better. But because the sisal element is essentially replaceable, you can use the allan key to remove the sisal cylinder and replace it with another in the future. Very happy and the cats love it.
