I am getting ready to make a t.v. stand for a cleint and not sure about the top board thickness. The stand will be 58"w x 24"d x 24" h. Looking at the sag calculator it say 1" would be fine, but being for a cleint I want to make sure it wont sag to bad over the years. In the pic there is a middle support. This will not be in the the one he wants.
This will be made from solid ro except the back which will be ro ply.
Here is the front veiw
