    I have an Imac that is about 23 lbs I believe, and an LG monitor that is 17lbs. Will this handle it? I’m 6’1″ and in good shape so lifting and pushing is not an issue.

      Hi, for M3B the weight capacity is 35lb, so we don’t recommend for 40 lbs in total. Best

    I set this up on my office desk and started using it yesterday. I believe I sat for only 1 hour the entire day. This is a well made unit and I love the workspace on top. I have two large monitors and they fit perfectly.

    This product was delivered quickly and was fully assembled as described. It was packaged very well and was easy to remove from the box and set up on my desktop. It is incredibly sturdy and easy to use.
