Review on 🐾 Domaker 4/5 Steps Pet Stairs 30 Inches High: Sturdy, Foldable, Lightweight - Ideal for Cars, SUVs, Jeeps, Trucks. Portable with Shoulder Strap in Black by Barbara Gonzalez

The product description said there were boards under the steps, but the steps still gave a little when my dog stepped on them. My dog is eccentric and won't walk on anything that isn't quite tight so they didn't fit us and we ended up returning them. That being said, I think they're great for a small dog or someone who is less concerned about having a little sag underfoot. They were easy to use and fold up nicely for portability with a built in handle. The ladder seems to be well made and can withstand even a large dog.
