Very sturdy, great usable space. I love the shelf under the desk top. I am able to have all my electronic devices plugged in and running, without taking up all the space on the top. The mesh metal of the under shelf also allows the electronics to breath, and they don’t overheat. It’s a fantastic desk. 
The packaging was also very well done, with extra corner braces, so no issues with damages during shipping. Would purchase again, and plan on purchasing the matching bookshelf soon!
