That's nonsense. The glass top only weighs 70 lbs. That's very light and easy to carry. Assembly is simply setting the glass top on the legs. There may be good arguments for not getting glass, but yours isn't one of them.Just and fyi, the glass desk is very heavy so if you dont live in a 1st floor or private home it could be hard to get in and assemble.....
I work on a glass desk all day. It's quite comfortable, functional and attractive, winter or summer.
OP: By the way, you can buy the glass top and use it with different legs, including the ones shown in the other desk you pictured. So if you like the top but not the legs, buy the glass separately and buy whatever support you prefer.
