This is like “If You Give a Mouse a Cookie” in that one thing is going to lead to another and another. I don’t hate the blue chairs, maybe paint the legs black and hang onto them until you can get what you really want? Was there something RH had that worked with it? A style you had in mind? I think now you need a bigger chandelier and some color on the window treatments and artwork.

Very pretty table. I think a tufted chair and a tall chair looks too heavy and detracts from the light and airy qualities of the table. I'd find something in a neutral tone and keep the wood legs a similar tone to the table. Crate and Barrel has many chairs $200 - $400 that would be in keeping with the style of this table.

I'd keep four chairs at the table and two chairs on either side of the window. They look too crowded together here as I group of six. I agree with others that your light has gotta go. This is going to be a stunning room.

Biggest issue?

Table i seems wrong shape wrong size for the space .......Length and width of room please..........? 54 or 60 table from RH ?

Not being critical but I don’t think RH makes anything that is ‘light and airy’! I think your chairs are fine and you could work with what you have by staining the legs towards gray if they really annoy you. I’d do that and focus on a new larger chandelier and window coverings first. Even if you don’t like the navy, it’s a ubiquitous ‘neutral’ in many prints and hides occasional stains (!) — pick a fabric pattern that you really like that has just a little navy in it somewhere and it will look great. Or if you’d rather a solid linen with a pleated header then find a couple larger framed prints that pick up the navy. Beverly suggested some great sources for chairs — Target also has a pretty good selection of curtain panels.
Tablecloths are hard to find for that size. You may want to use placemats or I have criss-crossed three runners (72”) which you can anchor with a centerpiece plant or arrangement.

Ikea has some nice linen panels that give the look of pleats when put on curtain rod. The curtains you have are too skimpy for a heavy dining table. N Johnson has some great input. I am not a fan of upholstered back dining chairs, but what ever style you chose,
have floor protectors on the legs. Maybe skip the rug.

I feel like that is a very casual table. The driftwood color (to me) makes it so. Is your style more formal and traditional or more eclectic? For me the table would look beautiful with white or off white tailored slipcovered chairs, and Id change the chandelier to something more simple. Id also add a round rug as I think the color of the wood floor is a bit too formal. Im no expert lol, so its purely opinion. What is your style?

Sorry...There is no good place on earth for round rugs. : ( A waste of money, and limited options. For all we know? The table was a mistake. Sorry on that too.

Well ,then a square one should be fine. Im sure that was an expensive table and she seems to love it so it does no good to keep reminding her that to you its a mistake. You have a great style and the round table choice that she made just has to be worked in ,she is asking for chair suggestions.

I asked as to room dimensions for one reason:

If the goal is a pretty room, new chairs.......whatever?

The time frame to return a thing is short. ......IF something else were better. Even from RH.

Good beginnings make good outcomes. We'll assume that is what the OP wants.?

I think the tufting is the major issue given the style of the table. This option from Arhaus might work and comes in lots of in-stock colors. I also agree with Beverly that you should change the light fixture. That will make a big difference.

Whatever chairs you decide, a rug is a must here — you need one with colors that will help connect the orange tone of the floors with the cool gray of the table. Right now, it looks like a floating gray circle in the room.

Just using this one as an example (the mock-up skewed the pattern and placement) …

Yes, definitely heavier panels. I like these oatmeal/gray PB ones:

Going to be blunt: I don’t like the bar cabinet in here at all. It’s too big and doesn’t connect with anything. I’d take it out and look for a more narrow console or buffet. Add art and accessories, and the room will come together. Example only:

Those are just general examples, as I don’t know the style(s) you like.

Re: chairs … if you search the name of your table, there are some examples of it with various styles of chairs and decor. You can see how this rug connects the warm and cool tones.

I need the size of the room IMO the table is very heavy looking for no real purpose and I agree a very casual table so maybe much more casual chairs. I do not see a rug the right size fitting in the space , yes to new drapes but not just panels on the sides IMO that is a cheap look either get drapes that are 2.5 x the width of the rod and get rid of the sheers .If you want buffet get one the same height as the table and the art you have is IMO too dark and for sure hung too high . Placee mats will be a better choice than a tablecloth or as mentioned table runners used like placemats I do that a lot. Never put all 6 chairs around the table unless this is needed everynight for dinner .I think a large round table looks best in a space that is also large a min. of 12x12' for that size round table.

I would step back and first decide on the direction/style you want for the overall room. You have a real mix and the type of chairs will set the stage for all other decisions in making the room feel better connected. With table feeling large in the room, suggest light feeling chairs and can add pads, if you like the look. I think it’s important to create a light, airy room.

As time and budget permits, coordinate by adding linen like curtains (on longer rods so they rest more on the wall), an updated chandelier, lighter art and use placemats vs tablecloth.

Taking another look at your situation…… if you can return the table I would. The gray is all wrong for the room

I think a fully upholsterer chair just adds to the heaviness of the table! These are from Hooker furniture. I have to agree with others here though that this table does not suit the size or style of this space.

Hi. The first photo seems fine to me, that the table has the look of the wall paint. Blue goes, I mean why not? Possibly a fabric like this? and are you needing another layer of curtains?

Some houzzers know about the 'curtain size tricks' -- the small window could have a much wider appearance with curtain rod that extends way far on each side... with your white sheers in the middle. I think navy and grey is a fine palette -- unless I"m missing something. I don't like the sticking out of console into the center circle - throws it off.
