Hard to say without seeing it. You could always add crown molding

It’s small/short. Only 26” tall and has doors on it. They will likely put stuff on top of it so that’s why I’m trying to fix the cupping.

OK scratch that idea then! Solid wood I assume? What joinery? Short of a plane or belt sander I’m drawing a blank without seeing it

Sorry at work and don’t have a good photo of the top from the right angle.

It’s being painted black so went with simple stuff. Solid doug fir simple butt joint pocket hole.

I have tried my belt sander, it just wasn’t feeling difficult to get just the right section sanded down and not oversanding the low spots.

It’s cupped like …. this is bottom—> ) <—>s my best plane for the job? I am a complete NOVICE with hand planing.

If you look at it from the side is it frowning or smiling?

Have you tried tightening the pocket screws more? You’ve got a crown on the top, if you can’t tighten the screws more you might just want to leave it be

I don’t think you want to solve this by removing wood. The better option is to force it flat – is there room to add a couple boards to the underside? Run them front to back and use screws to pull the top flat. Slot the screw holes at front and back to allow for expansion/contraction of the top.

The butt joints are glued as well, so tightening screws I don’t think is going to do anything. I think the same goes for attaching anything underneath. This is one of those I’m trying to fix something after it’s already put together sort of things unfortunately. Thanks for all the replies!

It may be glued but if it’s got a crown in the center then it isn’t tight there

You could cut the top off, then reprep or redo your top, and refasten. as a last alternative. A couple years ago, I had to redo a top because I didn’t like the final result. Was more work, but well worth redoing.

Agree, otherwise it become the “telltale furniture” and will bug you every time you walk by it.
