Question: How wide are the stairs themselves? All I could see is the width of the opening.
Document: When the stairs are lowered, it probably takes up twice the length of the space, so that's about all that's needed. The stairs are VERY sturdy, and the expandable parts on the side act as a hand rail for climbing up. Very slick.The only downside of this ladder vs others I've seen is that the opening is a fair bit smaller, probably 1/2 the size (because the size of the ladder is much smaller).
It's not cheap, but everything about this ladder oozes quality - except maybe their documentation. ;)They make it seem like it's a pretty easy install, and that you could potentially do it yourself - I decided to get a handyman I know to help me, and I am *VERY* glad I did.
I choose this ladder because I was restricted by the hole already in the ceiling, even though the opening was tight, it was easy to install. My wife and I installed it a couple of hours.
This ladder is a wonderful idea. The design is extremely clever and the ladder is high quality. However, I suggest potential users consider the opening space and the amount of space the ladder requires before ordering. In the smallest opening size available, the remaining space once the ladder is installed is small. While I would definitely recommend installing this ladder (2 people needed),  you might want to enlarge the opening space before ordering so you have the maximum space available for the items to fit.
BUT, once that was done, you can't argue that it's built like a tank and really well engineered.My ceiling was a bit beyond their default maximum height, so I also purchased an additional step - I believe you can safely add up to 2 of these according to them.
I've wanted to get a attic ladder for my garage for a while now, since it has tons of space available but accessing it is a pain. I had been checking out what was available at local home improvement places, but to be honest they looked like junk - then combine that with people on the net who complained that sometimes they fail, and it really didn't seem like the route I wanted to go.
We had a tight space, but needed access to the attic. This compact ladder fits the bill nicely. The ladder is easy to use. Even my wife is able to use this ladder without any problem by using the hook provided as part of the package. When it's closed, it is a very neat appearance. It extends easily and then the side of the ladder provides an excellent way to steady yourself and securely climb the ladder.
Since I'd rather not have it break and come crashing down on my cement garage floor, it's worth it for me. :)
Answer: yes
