Who decided desks should be 29" high?

I worked from home yesterday and it was a bit painful.  The desk I have is too high.

Yes, it used to have a keyboard tray.  But I don't like keyboard trays.  Maybe it's because I grew up with typewriters, but I don't like having my keyboard in my lap.

And if I use the keyboard tray, I am too far away from the monitor to see anything.  So I have to have the monitor sitting right at the front edge of the desk.  In which case, I might as well have a desk that is only 10" wide.

The tray is too low.  The desk is too high.  The porridge is too hot.

I know.  I know.  I'm being fussy.  But seriously, who decided desks should be 29" high?

I have only worked at one company where the desks were adjustable. Who logically thinks the same desk height works for me at 5'2" and my friend at 6'4"?

The chairs adjust.  But then my feet can't touch the ground and I need a foot rest.  My home chair is at the top of its adjustment but I am still an inch or more lower than is ergonomically correct.

I can't say I made an exhaustive search, but I searched Amazon and I visited Staples.  Almost all the desks are 29" high.  Some are 30".  A couple were 28 1/2".  I need something about 25" high.

Amazon had some adjustable desks, but it was mostly the working surface that adjusted, at an angle.  Those were probably intended for draftsmen.  And I didn't like the way they looked.

Yes, I could do custom.  But that is quite expensive.  At least in Arizona where wood is pricey.  So I am going to try to modify a ready to assemble desk and see if I can make it work.

My new job allows me to work half the time from home.  I can't be in agony the whole time.

Wish me luck.
