Topic tags/keywords: osb mdf desk

Moved to new house, larger home office and I need new furniture. I’ve got a rough design in my head but need some help with material choice(s).

The basic design of the desk will be a large U-shape following three walls. The actual desk-top will be supported in the back and sides by either OSB or MDF. These will be small sections so I won’t have to worry about the desktop bowing due to length or weight.

My question is whether or not OSB or MDF will be able to handle the compression of the desktop (which may have some shelving/bookcases resting on the desktop at the wall). I’m thinking the OSB would be fine (5/8” or 3/4” or whatever it measures these days) but would like some thoughts.

Anyone know if either would be fine? Just want to keep overall costs down which is why I don’t want to use 3/4 ply (which is double or more expensive than either OSB or MDF).

Thanks in advance.

Are you going for a laminate for the top or is this just a workbench more than a desk???

For short runs with an HPL and hardwood edge I’d say the MDF over OSB but I’d also want to be 100% sure there was no moisture risk

Ahh, let me clarify. The desktop will probably end up being 3/4” birch with oak or poplar edging. The OSB or MDF will just be the back of the desk that will be against the wall underneath and on the side of each section. I am anticipating each section to be about 4’ long (or possibly shorter). At least one section will have some book/storage shelves for binders and shoe-box size containers.

No moisture possibilities unless due to flooding or hurricanes.

(If I could figure out Sketchup, I’d rough out a drawing. For the moment pencil and paper is faster and easier for me to figure out)

If I am reading this correctly you want use the mdf as a ledger board. This will work fine, I have a desk the width of my room which is roughly 10ft. I have a printer cabinet in the center. On top of the desk is 3 computers and a light table. I have had this set up for 6 years.
