Several people who think that the table top is "tilted" connected the top assembly in reverse - makes me wonder about their spatial-perceptual function ...

I like how sturdy this is. It was easy to put together - easier than Ikea furniture. Some others commented the desk top was tilted when they put it together and others commented this was because one of the vertical pieces needed to be rotated. So, I paid attention to the angles on the drawing. (If the manufacturer is reading this, they should make this aspect more obvious on the drawing.) The wheels fit easily under our sofa.

Really nice quality and very simple to put together
