Post a photo of the chair. Maybe add to the leg? Add a cushion? Shorten the table?

I looked at leg extenders but most are round and the square I found are too big. Also I don’t want to damage the bottom of the leg. I think at this point I might try to find some nice pads that are going to add more height. From what I’ve read the chair height I need is minimal 18” and this is a ways off. I could cut the table legs down but if I get new chairs then the table will be short. This is a tough one !

Could you show a picture of the bottom of the seat of the chairs? Would it be possible to somehow add something to that part?

That is, detach the legs and add something then reattach them.
My son did some facebook marketplace shopping recently (ok I actually did some facebook marketplace shopping for him!) and found a nice antique round wood table for $50. But when he got it home he realized it was too tall for the (standard height) chairs he had bought. He detached the base of the table, cut some part off, reattached, and has a proper height table.

I looked at the bottom of the table and how the legs attach when I put it together this morning. The legs attach in a slot that cutting wouldn’t work. The only option for cutting is at the bottom. Which I don’t hate it I keep the table long term and never change the chairs. I have much to think about. I agree now that I think about chair pads on period padded chair would be pretty awful. Hmmm!

My

Did you look at the bottom of the chairs?

Yes I looked at the chairs. They don’t have a way I could add anything. I have to really think about what to do next. Thanks to everyone for the suggestions 😊

There is a product on Amazon called Gorilla Risers used to elevate chair legs. I think they can add up to 1.5 inches.

Adding height to the chairs instead of sawing off legs from either table or chairs sounds the most benign. Don’t give up, there has to be a way to add and inch or two to the chairs.

What do your chairs look like? any way you an elevate the seat with a cushion without making the chair look dis-proportioned? Or can you install casters on your chairs?

I have 4 of these. Because they have fabric seats I don’t think a pad on top would work or look very good. Unfortunately. After living with the dilemma for a few days now I’ve decided to cut the table legs (at the bottom is the only choice) about an inch which will help some. Then the table will be 29”. The table is a west elm thrift store find that needs some love on the top so this will be quite the fun project that I hope works out ! Thanks to all for the suggestions and happy holidays!

Let us know if your plan works out.

Before cutting the table legs, perhaps you can consider reupholstering the seat (that's an easy job) and either make a thicker seat cushion using thicker foam or make a matching cushion to sit on top that can be attached underneath with velcro. The back of your chair seems high enough to take the extra thickness of the seat.

That’s a great idea. As long as I don’t destroy the chair components that would work. I’ll be checking on that. Thank you !!
