I'm very pleased with the pet stair & so is my Chihuahua Jose pleased with it.  It's much easier for him to get up on the bed now.  Very sturdy.  He's only 8 yrs old now, but somehow or other, he hurt himself & wasn't able to use the other steps I had because they weren't high enough, but now there's no problem.  It will come in very handy when he gets older & maybe has arthritis.
