I thought I already reviewed this, but am being encouraged to do so again.  Hopefully you won't find 2 posts from me.
To say I'm disappointed is an understatement, I had such high hopes.  My dogs hate this thing.  The small bits of carpet are surrounded by hard plastic, which scares them.  I can coax them with lots of treats to get up on the bed using this, but no way are they willing to go down on it.  They avoid it if at all possible, and jump around it or off of it.  My dogs are all about 60 lbs.
I plan on cutting some pieces of carpet and attempting to velcro them onto the steps, perhaps I can make this work - otherwise I just blew a hundred dollars on something that is worthless for us.  Wayfair does not accept returns that are assembled or even disassembled.  So I'm stuck with it.
