When we bought a new bed, it was too high for our chubby dog to jump up on.  Rather than lifting her into the bed each night (she weighs 45 pounds!) we decided to save our backs and purchase these stairs for her.  They are sturdy and have a nice finish on them.  Like that the step treads are wide and have a carpet covering to alleviate slipping.  Just what we needed.  We are having to train Tipper to go up the steps since she's never seen a step before, but she's getting the hang of it.  Next, we'll teach her to go down instead of jumping off the bed!
