There is a chaise http://www.dwr.com/productdetail.cfm?id=4854 that I
quite like the look of but I'm not sure how the twist is done. If you
click on the View 6in Detail you'll see what I mean. The wood is flat
around the edge and then twists 90degrees on the x axis and 90 degrees
on the y axis to wrap around the top. It says 'carved from solid
walnut' but wondering if this is accurate. I guess it could be a
bandsawn from a solid chunk but seems more likely (to me) to be some
form of compound lamination. Thoughts, and if the latter any pointers
to where such a technique is described online.

No, not bent or twisted. If you look at more of the detail pics you will
see the grain is straight through, not around, the twist. A 5 axis CNC mill
job.

True. If you look closely at the last detail photo you'll see a joint at the
bottom of the curve and of course at the the top. The copy doesn't say it's
carved from one piece, just that it's carved from solid wood.
You're right, the top is a separate piece so I guess the piece just
twists around one axis. I've only ever seen bentwood pieces where the
bend is on the flat though, never twists hence the question. How easily
does wood twist in a lamination? I know it can do some pretty tight
bends but haven't seen any examples where it twists like this.
Look at the grain. It is carved (could be a cnc router), not bent.
You could steam bend/twist it, but the grain would twist with it.

You get great points for persistence. CNC routing setups start at
$6500. Carving a twist like that would take considerable practice,
especially to get the thickness consistant around the whole twist. If
your'e interested in carving, go for it!
I havn't tried it, but I bet with the right form(s), a lot of clamps,
bandsaw to resaw your board into layers, some polyurethane glue and
some practice, you could do it without the glue lines really showing.
Need to keep the boards in the same order they were sliced off. Tune up
the bandsaw on scrap 'til you have your slabs consistent in thickness.
Though the layers will be rough from even the best blade, the peaks and
valleys will match from board to board, leaving a near seamless glue
line without having to sand each piece (I have tried this part). You
might want to do a search for David Marks, host of tv show "woodworks".
He has done other bent laminations on his show and I wouldn't be
surprised if he hadn't tried a twisted one. See if he has a contact
link on his site.
Good luck.
I did check out the David Marks site, and he does have a chair in his
gallery that has a similar twist but there are no construction
details.. An email came back with the stock 'we're too busy to answer
emails' reply :)
I think I'll try the bandsaw/form technique and see how that works out.
With regards the forms, do you think a solid form, or just attaching a
clamp at both ends and twisting them would be the best way. Seems like
by just securing the ends the wood could twist more naturally.

Wanna bet?
Check the 2x4 pile at any BORG!
Now, if they can do it with cheap lumber, a real woodworker should be able
to manage an equivalent accomplishment in quality wood. <grin>
OR, you get lucky, and find some 'ready to use' parts in the 2x4 stack.
Then it's just a matter of applying the right 'faux finish' to make it
"look like walnut".
I'm not sure that is the case. Look closely and you can see where the sides
are joined together about halfway between head and foot. The grain
definately changes direction, which it would not do on a bent wood
technique.
The sides may very well be "Carved from solid walnut" -- you get $1000 plus
for a chair, you can put some time into it.

You will never get any wood to twist like in the images, even from
laminations
I actually wouldn't mind if my reproduction had the grain curving and a
CNC router is a little beyond my budget. Think I'll give it a whirl
after my current project is completed and post the results.
Thanks for everyones input on this.

Ammonia bending can easily achieve the 90 degree twist.

You could veneer it like that. Of course in this case it looks like it is
carved the way they say it is.

Absolutely gorgeous design, btw.
How?
Simple.
Soak for many hours (depending on temperature) in
Aminoethylethanolamine (AEEA) and form in hydrolic cauls, rinse, dry,
sand...
Could be Triethylenetetramine (TETA) and Diethylenetriamine (DETA) as
well. Depends on where and who did it.
Or not.

As you say, the sides look like a 90 degree twist. However, the top
appears to be a separate piece connected to each side (note seam near
top of chaise).
Also, the exact phrase is "Carved down from solid walnut,..." so I don't
think this precludes bent lamination of the sides.
~Mark.
Overkill. A 3 axis would do fine.

This piece is obviusly just an ordinary piece of 1 by 2 which is bent
and twisted to the desired shape. DAGS "wood bending"

I stand corrected. In the last of the detail pics it's indeed visible,
but it also seems as if the twisted part goes only to the middle of
the upward curve, just below the seam in the bolster there is a
discontinuity in the grain that looks like a glue line.
If i find the time i have to try and twist-bend some wood.
