It needs a heavy duty support just under the table top so it holds the top on a straight plane.
I think that I will have to build a frame that won't flex or warp. However, I would have rather just paid a little more and bought it this way.
The rest of the cart is quite strong.
Also, the table I bought was supposed to come 36"x24", it came 40"x 24", which I love. I wonder if I bought another one what I would receive?? I would buy another if I got the same thing....
