I was super pleased with this cat scratcher. Arrived in 2 days, doesn't tip over easily at all. I looked for one that weighed at least 20 lbs and this one fit the bill. My cat is small but likes to run and jump on her scratcher and the older one always was tipping over.    

Pros: No assembley required, very sturdy, & right height. Looks just like the picture. 
Cons: None at all
