Would some pictures help?

Where did you have your...
Where did you have your chair reupholstered?

Thanks Mark
Those photos help a bit. For example, our ottoman cushion seems to be about 1.5 inches thicker than yours, and its seam is nearly an inch above the sides of the footstool (where they curve up).
I also just think the "high density foam" is far too firm for the chair. I wrote too Knoll asking about thickness/density, but of course they responded that it is proprietary information.
Krenit, the chair was reupholstered by a single-person shop in San Diego who has done work for some of the modern furniture stores in the area. He did a beautiful job on the other aspects of the chair.

No offense, Mark
but your photos clearly show every cushion dimension EXCEPT the one that Warrigal seems most interested in.
Warrigal, I can't tell from Mark's photos how thick his ottoman cushion is. I also don't know how the age of his chair or whether it's been reupholstered. I do know that your original cushions were 45 years old, though, so I'm not surprised that the replacements are firmer and thicker.
Especially for a chair that's still in production, I wouldn't expect your upholstery guy to choose the wrong foam. He doesn't have to make any guesses as to the proper specs; Wombs are common enough that he can just walk to a showroom and touch one to see what it's made of.
And in fact, you can do the same thing. Every DWR has a brand-new Womb on display, and Boomerang usually has one or two vintage chairs. Have you visited those stores to see the foam on their chairs?
Anyway, here are photos that show the thickness of my (reupholstered, comfortable) vintage Womb cushions: Top photo shows how I'm measuring the ottoman cushion, middle shows the ottoman-cushion thickness (4"), bottom shows the seat-cushion thickness (also 4"). I didn't feel like unclipping the back cushion, but it also appears to be 4" thick.

Sorry, I did't see "its seam is nearly an inch above the sides of the footstool (where they curve up)".
The seams should definitely not be so high. Does the cushion fit onto the base without an air gap? Does the alignment improve if you flip the cushion over?

Oh, you could never offend me fastfwd. I'm an alcoholic...
and my ruler is just a board that some cheap-ass horny old dude picked up at Home Depot*.

If it's any consolation, Mark,
I'd put money on niceguy owning the identical item.

I
just spit vodka all over my Lilly jacket..

If it would get you to
smile in the next picture, it would almost be worth it!
Shame about the jacket, though. My sincere apologies. Send me the cleaning bill and the next round's on me.

mark I hold the copy rights to cheap ass dirty old dude, not tktoo2012 I charge 6 cents per use on this forum. I am so glad that person did not come in to our shop for the redo of the womb chair. foam can be tricky but following a pattern is not.

Thanks Fastfwd
Your photos help a lot. Yes, from looking at photos online and trying to gauge comfort, it seems these cushions are about an inch too thick (see the photos I've taken below). One inch is seems negligible, but it makes a difference.
It's also *extremely firm*! Much firmer than our Papa Bear seat cushion, which is 4" thick and definitely softer foam and much more comfortable (Papa was reupholstered several years ago by a prior owner).
- will "high density foam" compress?
- Any thoughts on what foam density/foam number I should request?
And Fastfwd, you bring up a good point about flipping the cushions. To answer your question, there is no discernible difference to me - it seems like the seam is in the middle, whereas on photos I see of other wombs, it looks like the section above the seam on the seat cushion is flatter than the lower section.
Photos are below (please excuse the computer and other clutter but I'm working from home today from the comfort of the Papa Bear chair)

Footstool
Oh, and re your other question Fastfwd, although the footstool cushion seam is about 1" above the side of the footstool, there is not really an airgap that I can see. But it does look overstuffed.
