My current working desk is a 1" thick table.
Even though there is not much weight on top of the desk (screen, keyboard, laptop ), the table's own weight, given its top dimensions, 60" x 30" ( 150cm x 75cm ) means that an underframe is necessary. Simply attaching four legs will mean that it will start to sag after a year or two. ( This is right; isn't it? )
I fitted it with a Bekant underframe from Ikea. I lowered the Bekant to its lowest height and am not using a keyboard tray.
It's not quite right. My knees will sometimes bang on the underframe.
I see on the market a table that's 72" x 24". This one is made from maple ( the first is birch ). But the thickness is 1 3/4".
Sure, a 72" x 24" would be unusual for a desk. It's meant for a countertop. Still:
Can I fit four legs, and just four legs, on a 72x24 maple table and expect it not to sag?
Or is this a recipe for me to have a nice table for two years, and then inevitably see it getting worse and worse, until it's quite bad after five years?
