Query: Good material - but weird

I got these for my pug - we had used the soft step dense foam products in the past. I wanted to try something new because his hips are starting to go. These steps are made of a durable material, but are at a very awkward incline and he can't hardly use them. I put a 4 inch book under the bottom step and that makes them usable. Without the book, he can't get up them. I've tried taking apart and reassembling - but to no avail. They also wiggle and are VERY LOUD. I'm actually back online here to purchase the soft ones again - unfortunately, I didn't keep my packing material so I can't send these back. :-(
