I vividly remember the desk holding my 15" Trinitron slowly bending under the load, but I don't know what it would have weighed. I'd imagine that 20" was a bear to get out of the car and make your way inside with.

Similarly, I'm not sure how 13 or 14 year old me got a 27" Trinitron TV downstairs by myself. 34 year old me would need an entire bottle of Advil for sure.
