How Ikea's New Joinery is Advancing Their Design
Seems the editor isn't aware that canting the legs is indeed integral to the design. The joint that they came up with is great for the flat pack design and simple assembly, but by angling the legs they are able to get rid of both the apron and the braces, because this does it by putting the legs in constant tension. Now if you go to IKea , you'll see that the legs still rack/ wobble - but far less.
I keep coming back to this article which illustrates evolution in table design quite well, because this concept (no substructure) is something I have spent a fair amount of effort on myself. I use a different technique (and a bit more complex) which uses tension and a broad stance against the underside of the top. The solution shown here captures the tenon in a tapered mortise giving a vise-like connection. The look is sleek but the result marginal and the volume of wood is a trade-off as a thick top is required.
RN, after posting that link, I had a flurry of studious views, received a bucket load of spam, and had one invitation to enter a pay-to-play European design competition. Ain't it grand?

So elegant The picture of the table with chairs Leaves me wondering when a complementary chair is forthcoming and Whether there would be a detail Wherein the rail of the chair back up from the topside Could be in line with chair leg from the underside As is and Wedged in only with the block from the underside Leaving the seat unsullied The bevel would be nice if curved
Very slick but I expect there's some transverse wiggle, probably could not dance on it.
Hi Chuck, please post a link to your work, I'm interested
You can see some here; www.chuckmackdesign.com though I have not upgrade the site for some time.

Pretty cool!
Scott, thanks for noticing. The concept with the colored legs is a true 'knockdown'. The connectors are spring steel clips from Modular systems - those together with the drop-in crossbar gives a sturdy result as does the 3-point single bolt system on the round table concept.
Nice prototype. What happens when the design changes? What happens when substrate qaulity changes? What happens with varied long-term addition stress (movement,usage, age)? Ikea furniture joints are NOT STABLE LONG TERM. You need flexible adhesive.
Is this really a material saving considering the tabletop has to be that thick?
It could if they constructed it the same as the tables in the link they provided

Really interesting and a great innovation. Question, I noticed the legs with the new joint aren't quite vertical. Do they have to be at an angle because they are not quite as strong as a apron and corner brace? Or was that an aesthetic choice?
I believe it's a bit of both. By splaying the legs, you set the physics up such that any weight on the table is driving the legs tight against the wedges, precluding wracking. And I think that aesthetically the table looks better with angled legs.
Angled legs would see a moment on the joint putting all kinds of stresses on the connection. Straight legs would only load the flange of the leg. This all assumes a vertical static load on the table. Bumping the sides of the table would put a moment on straight leg joints as well.
This is super cool. Hopefully we as consumers will be able to purchased router bits that enable the fabrication of this kind of joint soon!

Rain, you should get some kind of read-it-here-first award for positively linking the words "Ikea" and "boon... any time they move". Very neat.
That's a really nice looking table, so simple.
