Unlock the table top as if you were going to convert the dinette into a bed. The locking mechanism is on the underside of the tabletop, usually near the wall. Lower the base so it is even with the dinette seats. Some table tops must be turned 90 degrees for the table to lower.
Find the bolts holding the table to the floor. Use a socket wrench to remove the bolts, which may be hidden by carpeting. If this is the case, peel back the carpeting to find the bolts.
Lift the table up and off of the base and remove it.
Lower table leaves and lock into place. The locking mechanism is on the underside of the leaves. Check to see if the table is secured to the wall. If it is, use a cordless drill to remove the screws from the brackets. Remove the brackets from the table and the wall.
Find the bolts holding the table to the floor. The bolts may be hidden under carpet or under a panel. They are at each leg of the table or along a center pedestal. Peel back the carpet or lift the floor panel to expose the bolts.
