I just finished this "TV Table". I wanted something more comfortable to use while I watch TV. The top is 20" deep by 30" wide. Total height is 25".
The table has casters so I can easily move it out of the way and so the grandkids can move it around.
It is also a great study table for the grandkids. See photo. The legs also can roll under the couch so that the table is closer to the person using it.
I made it from red oak scraps that were laying around.
