IDASEN desk top.

I have a IDASEN desk (the motorized version). And a Bekant top on it. (I got the combo from marketplace).

I am moving and I am looking to make my top more sturdy, as I have two mounted 32" monitors on Dell MSA20 arms. This has caused a slight flex in the back of the table-top.

What I am looking for is suggestion on good table tops - that are sturdy to hold the weight of the monitors, while fits within IDASEN motors carrying capacity. Pardon my ignorance here.
