I was looking for some solid steps for my kitties because they are large cats & the plastic onesare not sturdy enough.  These steps are nice & big & solid.  Even my husband was impressed when he was putting it together.  My only design suggestion would be to secure the tallest step to the next tallest step somehow because the tallest step kinda needs a little security so it won't pull away from the base. We use a tie wrap for each cylinder to tie the tallest one to the next tallest one.  Otherwise it was a Purrrrrfect choice & the rugging is a nice color. A very well made product. We & the kitties are very happy with it!  They LOVE to just sit on the top step & look around & the steps are nice & wide enough for a big cat. Thank you !!! :):)
