Download at Mod The Sims

This will go over existing stairs and will be usable as long as it is placed over stairs. There's two designable areas. Be sure to read what the creator has to say and which stairs are best for this. You can download this at Mod The Sims.
I just moved this up since it is out of testing and has been posted at Mod The Sims. I'm not sure if this is different than the testing version (like the breast sliders) but here it is anyway. You can use this for all ages and both genders.
