Box was damaged on one side when it arrived, but luckily nothing was damaged and all the pieces were there. Was easy to put up, does help if you have two people to hold it during assembly. Only took about 20 min. Fairly sturdy, comes with ground stakes. Tarp easy to put on, uses velcro, but it is somewhat thin. Love the size and if you want it smaller you can just put together half of it. More importantly, the cat likes it!
