I had been holding off on buying one of these cat trees for years, simply because they're sooo expensive and I figured 'hey I could make that for half the price!'. Then I stumbled upon Wayfair. 

Long story short, I bit the bullet and bought this tree. Best decision EVER! It arrived super fast and to my surprise, was not that difficult to assemble by myself. Looks way more expensive than it is, and suits my three cats just fine.
