Fantastic purchase for my wife! In her words..."very easy to put together,  very sturdy, great quality cover, and finally,  most importantly, her plants are HAPPY!!!"
I can't add anything to that except... happy wife,  happy life!  Definitely a 5-Star product.  Wayfair did it again. 
P.s. since posting it on her Facebook page,  we've had to send the greenhouse purchase information to 5 or more of her FB friends.
