I will begin construction of a kids table and chair set this week. For the chair, I planned to angle the back of the chair backwards at 10 degrees starting 3 inches above the seat ht. Seat ht will be 14 in, and floor to seat back ht will be 26 in. I am using red oak 1-1/4 in wide; the depth (front to back) fo the leg will be 1-1/2 in. I’m also planning to taper the seat back starting where the 10 degree angle offset begins and ending at the top to 3/4 in.

While discussing this with a very experienced wood worker, he was concerned that the angle would create a weak point in the chair back since I will in a sense be cuting throught the grain.

Should I be concerned about the strength?

Will a 5 degree offset with taper OR no offset with just a taper be enough to be comfortable?

Hey Lee
chairs are made like this all the time. There can be a problem if the grain changes right where the cut is ,but most of the time it’s fine.

I can see the short grain issue here, but a1Jim is right, a lot of chairs are made this way. I don’t always advocate looking to factory mass produced furniture for examples of how-to, but in this case I think you might be ok.
