There is so much good information here and I have gleaned much of it. Vic has been a go to guy several times. Thanks for all you share with us Vic!

I understand the need to through bolt the hinges to the wall. I know the hinges can support over 400 lbs each but does the seat give any when you sit on it or does it stay relatively rigid? Thanks!

rigid, except for the hinges flexing as I said above.  Here is a pic of what they are supposed to look like (this is my wife's seat...)

 

This is my seat

 

Not sure why they are flexing, given that they are supposed to support 500 pounds.  Input/ideas welcome.

Wooo-boy Vic.  You better not have that extra slice of apple pie:)

 

I think the 500lb load spec is valid only if the load is placed at mid point between the wall and the end of the arms (that are bent).  Your load is probably at least at the end of the arms. If your seat extends out past the end of the arms, you have a lever, and that increases the force on the arms greatly if you sit on the edge of the seat.

I did, and I still can’t do that kind of work.

I see what you mean - that would be concerning. Maybe an extra leg centered opposite the 2 hinges to take the pressure off the hinge. You could use another folding hinge attached to a piece of 1x1 stock. Good luck!

heheheh.  My wife made her famous ChocChipOatmeal cookies yesterday.  First time in months.  CoronaAid comfort food.  I had 6 of them.  Sigh... 

 

It is the back arm where my butt is (not the knees end) that bends.  Hmmm.

I feel the same way about fly fishing, sewing, hunting, hiking (like the 3pins do!), playing an instrument, parenting, cooking and many other things.

Now that is a good idea.  I have a few spare hinges.
