I added Olov legs because I’m a coward and don’t trust the “wood” on the Kallax Shelves by themselves. (Along with smaller brackets to keep the table connected)

I also made a mount to hold up two more Olov legs in case I am doing heavier work on the table top.

Since the center leg isn’t screwed into a wall anymore and the base is supported by 2 legs I bolted the drop leaf arm to the table and added a brace into one of the Kallax shelves.

Old photos; forgive the mess, was still DIYing.

Been meaning to make this post for a while now. Might not be a surprise to folks here but I've not seen mention of it. I was so happy to stumble across this when planning my remodel as it's such an elegant solution. I have a modest 1 room flat with no space there or in the kitchen for a full sized table, and needed shelving along the wall. I love to cook and host, and wasn't gonna compromise on my ability to throw dinner parties.

It's perfect for me as I can just unfold the one side as you would the IVAR built-in table when I'm alone or with my partner, but can pull it out into the room when I've got more people over. I keep the large table cloth and extra table settings in the drawers, needed only in its full configuration.

Not visible in the pics, but I keep some old stacked stools in the narrow IVAR section on the right for extra seating, and they also double as mini coffee tables when called for. The only reason the table isn't quite flush with the shelving in these photos is because my baseboard catches the bottom of the drop-leaf. I plan to trim it in the future.

Altogether a wonderfully practical, versatile, and compact setup.
