It's a particle board covered by a melamine laminate.

Attempting to cut the above without "chipping" the melamine can be
iffy at best with a jig saw.

Use a good Bosch BiMetal blade that clears on the down stroke.

Bosch makes a 10 TPI down stroke blade specifically for this
application.

I forgot the blade number but check the 101 family.

Tape the cut line with masking tape, especially the top surface and
TAKE YOUR TIME.

Cutting thru the tape will minimize the possibility of chipping.

If you rush things, the blade will bend outwards leaving a crapping
surface.

Any chance you have a router or know someone who has one?

A router is the surest way to get a square clean cut.

Have fun.
