You need to post a photo of your mom's current dining table.

I'm trying to but for some reason it's not uploading

Okay post has been updated with a pic

Either use the complete set or replace it. Mix and match is not going to be successful with this vintage table.

In addition, the scale of this table is massive. Is Mom moving in a place larger than what she currently has? If not the table needs to size down.

If she loves the table, how about parson chairs? Then you only have to get a similar wood tone leg.

Like this:

You can do leather, fabric any color etc.

What specifically does your mother dislike about her current dining chairs? The answer(s) might well help guide your search.

Things to think about:

1. Are the seats at the right height for the table?
2. Are the chairs light enough for your mother to move them easily?
3. Do the chairs provide optimum support wherever your mother needs it?

Ideally, you would not address form without first addressing function.

Do consider Beverly's question re table size/scale. She's a pro. During my own recent-ish renovation, I learned it was important to make sure my chosen dining table would fit in my renovated home, with room for folks to sit, push their chairs back, and even walk around the pushed-back chairs! As it happens, I didn't buy my first dream choice table because it didn't meet those criteria. I'm very happy with my informed second choice, and I was over the moon when I sat in my old dining chairs and they fit at the table.

It really depends on what else will be going on in the room style wise/her taste and budget. I’d suggest moving in first to decide. If she is open to second hand that could be a good option. New upholstery on the seat pads (really easy) is third option and the money saved on not buying new chairs can be used to update and coordinate the room.

Does your mother have any other pieces she want to use in her new dining room? Does she have a colour scheme in mind? What will the chandelier/pendant look like? It would help to make suggestions.

Got the pics but not helpful We need to know wat your Mm dislikes about the chairs she has ? Al lwe do is guess if we do not have info. My first thought was new uphostery could make them look very different .I dislkke head chairs and I think there is lots of space for the side chairs they just are crammed together in the pic . But you need to get info from Mom

The photo looks like she will need skinnier chairs to fit under the table. What are the widths of the host chairs and side chairs?

Budget range for six chairs?
