sideboard is not aggressively MCM. Just get some MCM or very contemporary chairs and a new less farm-y light fixture -- and as much as I love table cloths, placemats were invented in the 20th c. They don't have to be MCM placements. Any old placements will do.

by the way, you don't have to replace all those chairs at once. You could just buy 2 at a time and it would work. It might even be better if you always had a mix of chairs around the table instead of a matching set of 10

@mytwo cents thank you for the input! I am very open to changing the light fixture; any particular suggestions on style? The one there now was only intended as a cheap placeholder upon removal of the 1980s brass atrocity that came with the house, but 3 yrs later I haven't improved upon it...

Could you do 2 of these over your dining table?

By the way, the drawers and pulls on your built in cabinet could be recovered in peel-stick-wallpaper in a fun MCM style I think I might paint that whole unit charcoal, just a deeper shade than the walls, and remove the top shelf and insert a hexagon wine hive in the bigger new opening. And then goof around with the drawer pulls with paint or peel-stick paper.

I cannot figure out where you have space you have builtins on one wall and a rad on the other and you need 3' all around the table for chairs I do not see where it would go.I do however think the one tall cabinet is not working either .

Not the right location for that 60s piece of furniture. Not really any room for the sideboard. Your dining room is charming and the sideboard is.........not.

Maybe you could use it under a TV screen somewhere.

Sloppy photoshop but you get the idea.

I don't think it fits your room. Perhaps it coud be used elsewhere. I would remove 4 of the chairs from around the table, remove tablecloth and place a nice runner and definately replace the light fixture. These changes would improve the look of the room.

@Paul thank you for the interesting idea! Actually, most of those white built-in drawers are false fronts due to a staircase behind so blocking them off is a more appropriate idea than you probably realized!

@susan49417, @BeverlyFLADeziner, @patricia I really appreciate your input! I am hearing you that there may not be room for the fairly hefty sideboard without the chairs feeling squeezed. I also appreciate the reality check that the sideboard, though belonging to my dear grandma, maybe just isn't that lovely and I should find another room for it, if at all.

@Pearl216 I don't think there's anything wrong with Grandma's sideboard. I love that you want this reminder of her. Might be expensive to ship. I'd like to know how you do it. 

I hope you find a place for it and all Grandma's dishes. If it won't fit in the dining room, maybe somewhere else, like maybe the adjoining living room?

@pearl216 That sounds great. My son settled on the opposite coast and I really wish I could magically transport all his books to him.

Not sure there is room for the sideboard. Your didning room seems a little crowded as it is. Might even suggest that you remove the tall cabinet near the room entrance. It's a beautiful piece but it just doesn't seem to fit.

I think the sideboard would work well as a console beneath a tv in another room. Do you really need to have your dining table at full length with all the chairs around it? How big is your family? I have an Eastlake dining table with five leafs. It can seat up to 16 people. But I have it broken down to 6 chairs in my dining room until I need it. (And, yes, I have my grandmother’s banquet length damask table cloth from the 1890s that “fits” the table. And I have used it!).

@ptreckel thank you! No, the table is not usually extended this large (110") - in the photos the room was set for 14 guests. Usually the table is smaller and has only 8 chairs, so that probably does help the room feel more spacious, though that wouldn't change the width of the table, which is the concern many are identifying about fitting the sideboard.

I don't think it fits (physically) in there, but it's a great style for a living room. It doesn't scream "sideboard" or "buffet". It's just an elegant cabinet that can go anywhere. (You just have to lug the china around for special meals, but I think that is okay.)
