There are a few different portable steps on the market, but none are as rugged, stable and nicely made as these Safety Steps. Safety Steps are the original and still the best on the market. 

They're made out of strong, rust-free tubular aluminum, and are lab tested to support up to 1000 pounds!

Thee platform is 14" x 11" and 8" high when open. The top has quality non-slip tread.

It's perfect for smaller vintage trailers. It folds to just 4" thick and has unique secure double-locking safety legs. The legs have a wide stance and rubber tips to prevent tipping regardless of where you step on it.
