The table height is actually 37", not 40". The height of the metal guard in the back brings the furniture to 40". We ended up buying 5" risers to make this a true cafe-style standing workspace. The piece is solid; however, the quality of the hardware isn't top-notch. Pre-drilled holes didn't line up perfectly and the table legs are awkwardly bent. Generally happy with it - our hastily-constructed work-from-home office is functional and comfortable
