It was easy to assemble. It took me about an hour and a half and I've never put a desk together before. The instructions were very clear. 
The desk was shorter than I expected but that is bonus for me. I am 4' 11" and have never ever had a desk in which I could sit with my feet flat on the floor and comfortably reach the key board. As a writer, it's a 5 star plus for me.  It's by far the best ergonomic desk for a petite person. For a taller person the feet are somewhat adjustable but probably not more than an inch. Check the height in the measurements. I love the L configuration. I have room to spread my research. A huge bonus. Great product!
