How is it supposed to turn into a two step stairs It was compressed into a ball! How long does it take to inflate up, so it will resemble at stepper stairs. I do hope it is the genuine artarticle! Please let me know what I do about it, how long do I wait, for it to inflate

My dog ​​loves these stairs. easy to wash and clean

The cats happy too

Memory foam didn't expand on one side

Great little set of steps for my dog . Fits in really well and not overly big . Don’t be put off when you open the small box to find no more than a small roll of foam . You have to allow 48hrs for them to expand !!
