I'm using this against my bed so that i don't get woken up everytime my dog jumps off the bed. She weighs 70 pounds and these stairs are very sturdy, no issues with weight at all.  For some reason my dog will only go down them as she is afraid going up, but thats just her being afraid. I took a star off as I don't really like the slant in them... I find the slant too downward, it just causes problems for dogs that may already be afraid of stairs. I would recommend as product is very good quality and sturdy.
