If your not looking for something fancy looking and a cheaper option. I bought a flush mount table insert off Amazon for $5, pvc pipe from Home Depot for less than $10 and a table off of Amazon for $40 (scored one in the warehouse). It mounts front and center and it’s pretty sturdy. Obviously not strong enough to stand on it but it does the job and much easier to eat on/have drinks on.
