I purchased the 5 Panel Free Standing Gate several months ago. As a telecommuter, this helps me immensely! My office is in the living room so the gate allows my two Aussies to stay in the same room, yet separate from me. They cry less and are calmer, allowing me to concentrate on my tasks and not worry about rolling over them with my chair. 

Set-up is super easy. It can be closed and put away very quickly. It comes with a handy Velcro strap that you strap on it to keep it closed. It does not need a lot of space when closed. I place the standing closed gate by the side of my desk at the end of day. 

You could also leave it open since it has a door that you can easily walk through as needed. It is beautifully made and very sturdy. Since my apt is small, I stash it away every evening, which works out great since it signals the end of my work day! 

Pros: sturdy, no assembly required, easy to use and store
Cons: Not enough color options
