Simple to set up and sturdy. Comes with clear instructions and required Allen wrenches. I got two of the cheaper woven basket versions. I thought the basket version would be more comfortable due to its softer material and rounded shape. Cats are using them on both of our desks! Our largest cat is 15lbs and it has no problem holding him for hours. No wobbles!
One of our cats started pulling on the basket material and ripping it. I doubt he'll rip a hole through it, but something we'll keep an eye on. I hope there are ways to purchase basket replacements in the future.
