Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Great buy! Excellent quality and design. I don't think it can be installed by one person in one day though. I would say two people and two days. March 10, 2015
Rated 5.0 out of 5.0 by I liked the stairs I think for the price these stairs are a very good quality. Was a little tricky to put together. Had to watch the video a few times. Only problem I had was there was a gap between the top of the rail on the platform and the rail I had to add to keep anyone from falling down hole. Maybe I did something wrong but we fixed it by adding to the railing at the top. July 29, 2012
