Ikea Hack: Stolmen
Ikea makes some good products. Sometimes it's just parts of their
products that are good. I seldom assemble Ikea products without modifying them
in some manner to suit my tastes and higher construction standards. What I like
about the Stolmen system is the adaptability and expandability on account of the brackets. Ikeas also manufactures open shelves and drawer components as part of the Stolmen line.
I wanted to make use of the brackets but I was unimpressed
with the upright posts that made up the basis for the whole assembly. They feel
flimsy and they are only affixed to the floor by a single adjustable bolt in a
manner that is convenient only for homeowners with few construction skills. This flimsiness is only partially overcome by additional struts that can be attached to the posts with bands and also require more holes in a wall, all of which detract from the look and the mechanical design.
The
posts are adaptable to various ceiling heights but are still limited to a range between 210-330 cm. Both the posts and their
necessary mounting fixtures were clear weak points in this system.
I thought it would be easy enough to find some steel pipes
to substitute for the Stolmen uprights but the fact that nobody else had done
this before me should have been a clue as to the inherent difficulty. Doing this hack in
China only made it take a lot longer, 3 years longer than I had anticipated. I began by measuring the diameters of the
Stolmen uprights. Officially Ikea lists the diameter as 2” or 5 cm. In fact,
the posts have two outside dimensions. The lower, wider section is 46.5 mm OD; the
upper, 39.8 mm OD. Ikea includes two sets of plastic sleeves and metal bands for the wall struts with each bracket
to accommodate these different sizes. The plastic sleeves act as a kind of cushion to protect
the surfaces from being marred and the increase the grip.
These outside dimensions are not commercial standards, which is Ikea’s corporate way of compelling consumers to buy the uprights if they want to take advantage of the whole system.
The breakthrough that I discovered came about by trial and
error. Using either set of the
plastic gaskets, I found that no commercially available pipe allowed for a secure fit. But
when I used two halves from the different gaskets, I found that the brackets
did hold securely around 1 ¼” pipe, which has an OD of 42.0 mm. This not
surprisingly falls within the dimensions of the upper and lower sections of the
Stolmen posts.

The pipe vendor whom I found to cut and thread the pipes
only carried galvanized and bare metal piping. Black pipe seems to be unknown in
the mainland. I wanted black pipe, but I settled for the galvanized. And as another indication that the
mainland is not DIY friendly, the pipe fitter didn’t sell floor flanges nor
did he understand how such an attachment functioned. I had to order the floor
flanges through Taobao. The pipe fitter, in spite of being helpful enough to fabricate
everything to my specifications while I waited, likely still doesn’t understand
what he constructed. The Chinese word for flange is: 法兰 fa3lan2, which is
clearly a borrowing. According to
the Taobao merchant, such fittings are only sold abroad because Chinese don’t
know about them. Another great example of circular marketing analysis.

The possibilities are quite boundless |
I found that attaching the clothes rod helped to steady the assembly as I first lowered it onto the concrete anchors in the floor and then eased it to engage with the anchors in the wall. |
I discovered this hack earlier when I first installed a Grundtal shelving system and was unhappy with the fit of the posts.
Please let me know whether this is helpful. I’ve included
the links in case any mainland readers want to tackle this project on their own.

Thanks for the good info. I think your post is the only place on the entire internet where the Stolmen pipe diameters can be found!
@Shawn Clover
I'm glad that you got something worthwhile out of this. I hope you share your hack when it's been finished.
