Just drill a hole in the side for the tubing to come out.

Thanks clt3 -- pretty close to the concept I had in mind. I think I want shelving but at least this gives me a place to start.

Appreciate your taking the time to respond!

Or just attach some baskets to the back of the nightstand for the mask and drill a hole in the back and keep the main body of the equipment inside the nightstand. You can get longer and narrower baskets so the stand doesn't have to be pulled out too far from the wall.

Jann, you can always attach shelving to any nightstand yourself. Just get some bracket and wood and voila!

Or you could just put everything in the nightstand drawer with a hole cut in the back for the electrical cord.

Here is a company that makes nightstands for the C-Pap machines.

Thanks Beverly27 -- this is such a good example of the functionality that I'm looking for.
