So, we have four dogs. Two medium size dogs and to itty bitty dogs and our bed is rather large. All the dogs have figured out how to get on the bed but my 20 month old struggles. Don't laugh at me but we use these stairs for her to be able to get on and off of the bed without hurting herself and they work wonderfully. Ingenious idea!!! When the dogs are feeling lazy they use them to but it truly is more for my daughter and it has saved us a lot of heart attacks. Love these stairs.
