Would you include corner braces for the seat to rest?

I drew the plans for these chairs based from a chair I saw on youtube. I did not have the original plans, so I don’t know if these should have corner braces. There are a total of 8 chairs.

I am to the point where I have the back and the fronts glued together, but the sides are only dry fit. I haven’t built the slip seat yet, but plan to cut them out of a nice plywood, and then my wife will pick the fabric/upholstery.

I feel like I should add corner bracing for both structural (lateral) strength and to give the slip seat a little extra support. I would make the corner braces from walnut to match the chair. Do you think the corner braces are necessary? If yes, corner braces on the back and front, or just the back?

Also, if using corner bracing, would you fasten the seat to the corner braces, or just let the slip seat rest on top? There is a 1/4” rabbit on the front and sides so the seat will be recessed.

I would add the braces just to insure structural strength.

You ought to add the braces. My first set of chairs did not have them and depended only on the mortise-tenon fit. After a few years these began to loosen. They weren’t “grand-kid” proof. The braces are relatively easy to do but be sure the fit to the sides is good. I fasten the seat to the braces since it is convenient.

Can even be like these….Add a hole in each, to fasten the seat.

Okay, thanks for the quick responses.

I’m convinced. I do think I’ll proceed with getting all the glue-ups, and then I’ll measure the angles with my protractor so the angles will fit nicely.

Y’all know this is going to add a weekend to my completion date…..

1+ on corner braces. Pre-drill and counterbore the braces before installation. That way you can screw the slip seats in place from underneath.
Here’s a blog I wrote about attaching slip seats, and corner braces…
In that example we used threaded inserts, but I think plain ‘ol screws work fine too.

No going around that. The chair won´t last without, even if it looks and feels structurally sound.

How will you account for people leaning back on their chair, putting stress on the back M&T joints? Corner braces certainly can’t hurt. I think it is a good idea.

+1 to corner braces. Takes a little time but chairs always, always take a ton of abuse.

Just to follow up, here is what I came up with. There is a groove, 2 screws, and glue for each corner brace. There are 8 chairs.

Thanks for the advice.

I Would also do corner blocks or braces.

I would also use perelli(spelling?) webbing for the seat. This allows for the seat to give a little more. It creates a better feel and will prolong the life of your foam.

I believe perelli is a brand name. There are other manufacturers.

Stuff is expensive.
