The Bedside Commode Has to Clear the Bed and the Doorway: Measure Both Before You Choose One
Measure the gap between the bed and the wall, the doorway, and the walk from the bed, then compare every commode against those numbers instead of the photo.
A bedside commode looks small in the store and large in a bedroom. The first thing to fit is not the seat. It is the space between the bed and the nearest wall, and the path from the bed to the door.

Take three measurements before you choose one. Measure the height of the bed at the edge where your parent sits. Measure the open gap beside the bed where the commode would stand. Measure the narrowest doorway on the route to the room where the commode will go.
Match the seat to the bed
Ask the hospital therapist or nurse what seat height they recommend, and whether they assessed for a commode before discharge. Their notes are the best starting point. If they did not assess, ask who at the hospital or the doctor's office can answer that question before you buy anything.
Then check the seat against the bed height. A seat that sits far below the bed edge asks more of your parent than a seat close to it. Compare the two numbers with the therapist's note in hand.
Check the frame, the arms, and the weight limit
Look at the stated weight limit and make sure the person who will use it is within it. Look at the arm width. Many commodes with arms are wider than the frame suggests, and the arms can block the doorway even when the seat fits the bed.
Check whether the commode has a splash guard and a lid, and whether those parts add depth. Measure the full footprint with the arms open and with any part that folds out, not just the base.
Walk the route with the commode in mind
Stand in the doorway and picture the commode coming through it. Check for a threshold, a rug edge, or a cord that catches a wheel. If the commode has wheels, check that the brakes lock on your parent's floor surface before the first use.
For Medicare coverage of commodes and other equipment, the Medicare.gov durable medical equipment pages explain the doctor's order and supplier rules. The NIA home safety guidance also gives a plain checklist for clear pathways in a bedroom. Use both as reference, and use your measurements as the decision.
