    I'd happily pay for the traditional physical IKEA yearly catalog. I suspect that if they sold it in-store for a few euros (€2?) just to cover printing costs, many people would buy it. It's more than a product list, it’s a cultural artifact, offering a window into the aesthetics, values, and lifestyle of its time. I still keep their old catalogs, and I’m not alone.

      Fun fact - Getty Images used to send physical albums of their stock photo collections.

      It was some 25 years ago, I was doing freelance for an ad agency, and while visiting the office and waiting for my appointment to finalize some paperwork I was browsing through these. When my guy finally showed up to pick me up he asked if I liked them and said - you can get these for free, just write them. So I did and they mailed me 10kg worth of albums. Just like that.

      Just a cool memory from the past. Back then internet wasn't that rich, mobile phones were novelty, and when you visited a musuem or gallery and liked you bought a massive album to hold on to your memories.

      These days, when visiting such places (think sistine chapel) I don't even bother to do pictures at all. If I want to recall something I can find endless stream of top quality pictures made by professionals with equipment worth as much as my car and in clinical settings, with no crowds and perfect lighting.

      It was one if not the most effective advertisement which I’ve encountered in my life. We got it freely every year with post, and I dreamed as a kid to have such houses and flats which could be seen in them. The brand stuck me so well, that it’s my go to furniture store, since I moved out from my parents. I wanted to read it again last year to have some ideas for my new flat, and I was devastated when I’ve figured out that it’s not printed anymore. Even as I’ve been continuously online for 24-25 years, a digital “version” of it will never be the same. I won’t ever read it just for fun, which we did back then so many times (my whole family), that it became utterly damaged until the next year’s edition came. I would easily pay for it.

        I remember paging through the IKEA catalog and OTTO clothing catalog at my grandparents house in the summer. We were bored. I think this is just nostalgia. Today even if there was a print version, it wouldn't mean the same to people as it did back then. There's so much more stuff competing for your attention online all the time.

      > And behind the scenes, work on the next catalogue had already begun – a process lasting several months and involving planning, construction of interiors, photography and filming, all led by catalogue manager Mia Olsson Tunér.

      It is naive to assume printing costs are the only costs involved.

      I feel comfortable assuming IKEA had a better understanding of the economic fundamentals of the catalogue than HN commenters.

        No one is assuming printing costs are the only costs to produce the catalogue. The point of pricing the catalogue at printing costs is to cover the marginal cost of offering the catalogue for sale. The fixed costs of producing the calendar are incurred either way.

          Same way as IKEA restaurants were serving decent quality food for dimes.

          It was business decision. People were thinking - we have a day off, we could go there and there, do some shopping, and then we go there for food, or we could go to the IKEA and eat there.

          If you're "slave to the IKEA" and want to cherish your free day with consumerism, it was a no brainer if you wanted to shop on a budget and eat for free.

          Unforntuantely, catalogues are gone and so are days of cheap food in IKEA.

          A company I worked for stopped doing physical catalogs too - after having done so for a very long time. The cost to produce the catalog was insane, and had quite a bit of dedicated staff working on it full-time. Making a catalog is a specialized skillset, and has little overlap with the business' core competencies, such as website administration.

          Over time, the revenue attributed with the physical catalog declined year over year. People said they wanted the catalog, but it didn't translate into attributable sales. The ones that did order from the catalog were often the smallest, insignificant orders the company took in. The website and online advertising are where customers gravitated towards, and remain today.

          The amount of people that actually want a physical catalog, even for IKEA, I would wager pales in comparison to the amonut of people that want to browse the catalog on their phone or tablet. Pricing changes, stock comes and goes, products get discontinued, colors/materials are changed, etc. The website is always up-to-date, the physical catalog... is not.

          When I read comments like yours, I interpret them as people wanting nastolgic items more than marketing materials or ordering guides. The costs for the company are just too high to produce those anymore; well over $2 per catalog someone up-thread mentioned - we're talking more like $10-$20+ these days (not accounting for anything except print costs) for a full-color, glossy/professional catalog with hundreds of pages.

          I have serious doubts IKEA printing catalogs today would garner any new business. They would give away (or perhaps sell) some copies to existing, long-time customers with a fond memory of the brand and their catalogs - and I'm afraid that's it.

    A bit OT, but why is ikea internet store (any country) designed to be so unusable? Lists of available components hidden in pdfs tucked in obscure menu, no way to find compatible components, search flooded with tens of thousands of "combinations" — I mean, they obviously know what they are doing. What is the goal of making it such way?

      Also: why can't they show all sizes of a product jusst like when choosing t-shirt size on a normal shop?

      e.g. this dresser is available in many sizes but you wouldn't know from the product page: https://www.ikea.com/us/en/p/storklinta-3-drawer-chest-white...

      At best you can then search for "STORKLINTA" but the result list has the other sizes mixed with all sorts of other products such as beds: https://www.ikea.com/us/en/search/?q=STORKLINTA

        It's not super hard to back up (using the "bread crumbs" on the page you linked), to "Dressers & chests of drawers", pop down the "Series" input selector, and pick STORKLINTA. That gets you [1] which I hope shows all the dressers of that name.

        Not to explain away Ikea's byzantine system, a difference in size usually comes with a difference in use and environment.

        While a T-shirt has the same purpose in S M or L, a table isn't the same if it's lower smaller than 50cm or longer than 1.5m, or lower than 60cm or higher than 70cm. In a standard shop you'd call that a night stand, or a coffee table, or a kids' table or living room's low table etc.

        If you think of it as shopping for an environment (same as half of the in-shop experience: they'll show you full rooms where you can see products fit together) it makes sense. Somewhat.

      IKEA likes to find ways to get you into their physical stores because they know you’re going to end up buying more than just the items you came for.

      So they have a website that sort of teases you, but isn’t actually good enough to replace the physical stores.

      You’ll start on the website, but get frustrated with it and eventually just drive over to IKEA to find the items you want. And you’ll also come home with some candles, picture frames, and a couple packs of frozen meatballs.

        Also to note, shipping prices are egregious compared to the product prices. In most cases shipping a single product will cost 2 or 3 times more than the product price.

        They made efforts during COVID so they're obviously aware of the issue, and I'm sure they al see it as lost opportunity, but probably still don't want to eat the cost or go full Amazon and have their own centers.

        TBH as a customer I'm fine with keeping in-store price low instead of subsiding the online store.

          Shipping has always been a strong point for Ikea. Just look at how efficient most of their stuff is packaged, usually into very neat rectangular packages. They can fit a ton of stuff into a small volume, which improves shipping cost a lot. Last mile will always be relatively expensive, but shipping a truck load or a 40ft shipping container is relatively cheap. In the end it all comes down to cost per unit of volume, compared to the raw product cost per volume. A dense product will not nearly be affected by high shipping prices as much, and due to Ikea being insanely good at packaging, I expect they are outcompeting the rest of the market at this game by a decent margin.

      I'm probably part of that problem.

      While I don't shop that much at Ikea, I still remember their product lines, will sift through the dozens of combinations and PDFs, and take notes while looking at the building instructions to see what could be done with a product.

      Most of us will choose Ikea for the flexibility, and will happily do some amount of research anyway.

      Until reading your comment it didn't hit me that the site was so different from other brands, like Apple for instance. And I sure don't enjoy Apple's site. But then Ikea shops aren't traditional shops either, if sifting through pages of products isn't your thing, walking through sinuous paths all around the shop won't be either.

      It's a fundamentally different public.

      This is completely anectodal, but I have a friend who works there and he talks about a very change-averse culture.

      He has to sit through talks about how Ikea is a bussiness that already works very well and the most important thing is to avoid any changes that have even a 0.001% chance of making it not work. Many relatively trivial deployments have to be approved by a lengthy international bureaucracy, with a focus on preventing any automation that can eventually result in workforce not being needed. Things like that.

        Yep, this is it. I've heard similar.

        I worked for a few years at a 100+ year old privately owned (same family) B2B supplier with insane profits. Website was outdated but highly practical, sales/CRM (if you can call it that) systems were mostly command line and hadn't changed fundamentally since the 1980s. These systems worked, and any proposal to change anything took months of meetings and debates and review of every cost/benefit possible. Proving that a change directly translated to a clear revenue metric was nearly impossible– for at least this niche, would more modern sales software actually translate to more orders? (answer: not really, a question reanalyzed every few years in depth). Would a nicer website get more conversions? (also no, something A/B tested to death every few years). Changing the position of one product grouping by a few pixels might be a 6 month job, lol.

        By contrast, their fulfillment center was cutting edge, highly automated, and relatively experimental– if it improved the speed and cut costs, they jumped right on. These are much easier to measure as profitable.

      The 'Acquired' podcast episode on Ikea speculates that their "buy in person" was historically a cost advantage (especially over pre-assembled furniture that cost $$$ to deliver), as they didn't have to pay shipping/delivery. In the modern era of "expect free shipping as long as some minimum amount is spent", online sold and delivered sales have less profit margin, and one could imagine an intentional business decision to try and keep the in-person experience the "preferred" one for customers.

    Crazy how few of their decades old designs look "wrong" today. Their combination of high quality design, low price, and (depending on price...) workable to good build quality is pretty unique.
    • atombender
      11 hours ago
      Mind you, a lot of their designs are cheap knock-offs of contemporary designs.

      * The POÄNG chair is a copy of Alvar Aalto's 406.

      * Nakamura's earlier POEM copied both the 406 and a chair by Bruno Mathsson.

      * FROSTA (now discontinued) is a copy of Aalto's Stool 60.

      * KROMVIK copied Bruno Mathsson's Ulla bed frame.

      * BORE copied Mathsson's Karin chair.

      And so on. Ironically, some of these also have become classics of their own, or at least sought-after vintage objects.

      IKEA sometimes comes up with original, sometimes novel designs, but generally they copy better designs with worse manufacturing quality rather than coming up with original ones.

      And they are genuinely worse in terms of construction. For example, if you compare the wood quality of a FROSTA with Aalta's stool it's night and day. FROSTA is just plywood cut to size. The Aalto stool is solid birch, with a plywood top and an elegant solid birch veneer for the edge band, and the legs use a unique plywood-like join that is a thing of beauty [1].

        Personally, I support any sort of cheap knock-offs as long as they more-or-less last for some time. "Alvar Aalto's 406"'s price is JP¥304,200 from what I quickly found. Most expensive POÄNG is ¥16,990. Almost 20x cheaper. Increasing QoL for average people who can't afford expensive things is actually good.

        Yes, I understand the whole "copying isn't innovation" part of the argument, but it is for the greater good.

      I just renovated an Ikea table from 1980-something. Actually found it in the catalog too.

      It's solid wood, so it'll probably last another 40 years at least.

      The more striking thing is checking them against each other.

      The 1959 catalog had thin, svelte, curved and up angled designs. The Mid 80's had plump, puffy, overstuffed and was quite tame-loud, whereas the 2020's has "I'm not here, white-black-pop of color" aesthetics.

I have been trying to get a hold of them for weeks now, but with no luck so far. If anyone here knows someone at those places, please let me know.

    One of these catalogs is connected to an interesting story that happened to me not long ago. The situation took place in Poland. I recently visited a friend’s house, and there my attention was caught by an old chest of drawers that must have been made during the communist era (the PRL period). I asked my friend if he knew what model it was, since there weren’t many such pieces made in those days — there are catalogs and auctions, so these things must be documented somewhere. He told me that he had already searched for it online but couldn’t find anything.

    Out of curiosity, we moved the chest of drawers and looked behind it. There we found a small label with a production date (probably 1963) and the name of one of the Polish state-owned furniture factories. There was also the model name – quite enigmatic – and when I searched for it online, nothing came up.

    The mystery intrigued me so much that I spent several hours going through old PRL-era catalogs and online auctions. After quite some time, I finally came across a photo on an auction site where someone was selling a similar piece – another item from the same furniture set. The description was very detailed; the seller even claimed it was a unique piece and included an extensive history of these furniture items.

    It turned out that they were designed by Marian Grabiński, and the set was originally a wedding gift for Ingvar Kamprad, the founder of IKEA. Kamprad liked the gift so much that the furniture went into mass production – but only in Sweden. They were never available in Poland!

    The auction also included scans from one of the old IKEA catalogs from 1964 (pages 111–114, see thread link). But how did these pieces end up in Poland? I don’t know if the Polish company actually produced them for IKEA, but according to the description, at least prototype series was made in Poland and distributed among some communist party officials in limited number. This was never available to buy in Poland.

    As I later found out from my friend – his aunt actually was a communist party member and even held a fairly high position there so it made perfect sense.

    I was interested in when computers started showing up. I flipped through some years quickly. I see a terminal on page 158 in 1984 ('84:158). What looks like an 8-bit computer at '85:103 and a Mac at '86:190. Anyone see something earlier?

    This could be a game. When was the first flat screen TV? When was the first CD rack? When was the first microwave?

    There is a record player at '20:156. Did record players go away and then come back?

    There are at least two typewriters in 2020 ('20:56 and '20:61). I wouldn't have expected typewriters in a 2020 catalog. Maybe that's a Swedish thing? Are typewriters still common in Sweden?

      One thing to note is that the setting of a furniture catalog is meant to establish emotional connection to a setting which could cause you buy furniture.

      Midcentury stuff like record players came back into vogue in the 2010s and 2020s; a typewriter would be one extension of such a retro fashion. Even today a vinyl is a common item in the merch shops of modern artists and bands. https://a.co/d/9FFBuEF

    Woah...that brings back some memories. In a whole different timeline 22 years ago I was printing them for literal months. We did all European versions and it was 8 weeks of nothing but IKEA catalogs. They were highly optimized so for a language change we only had to switch the black cylinders. The whole IT was bonkers for the time we used SGI workstations for pre press and had like 100 bonded dial up connections for the mass of data. The pages came as TIF files and a catalogue was around 300GB. We were a rotogravure shop and did around 13m/s of 3-4 meters paper in width and around 4-5 kilometers in length. I think a whole run was 50 metric tons of paper. Good times but incredibly boring if the machine was dialed in.

    I hadn't noticed the lack of printed IKEA catalogs until now. Seems like they stopped making them in 2021. They used to just appear in the mailbox. (I'm in Sweden. They were literally sent to every household in the country every year.)

    I'm a fan of print layout catalogs over database driven web sites. Can't AI help with making an appealing paginated layout of a product database? I'd be happy with a 1 GB .pdf.

    Edit: Shoutout to the electronics supplier Reichelt in Germany for keeping the catalog alive:

      No need for AI --- I used to work up automated typesetting systems for a previous employer --- feed in the database as a properly tagged XML file, provide all the graphics in a folder, and a couple of typesetting runs later, one had a fully paginated PDF w/ ToC and Index.

      The problem is, no one wants to pay for this since no value is seen in such a paginated view --- even if AI could create such a typesetting routine.

        I mean, what I'm after is a page layout that is designed with compactness and readability in mind. Going from a product database to that requires quite a lot.

      I don't think you need AI but you do need to think about the audience for the printed catalogue.

      A few years ago I did the website for a retailer of clothes for the elderly, and they were doing it old school with the catalogue, printed order form and excellent customer service by phone. Their niche was the demographic every other clothing retailer avoided. Unless you have a similar niche, you have to ask about whether a printed catalogue is worthwhile.

      AI could potentially help but how do you plan and budget time for that? It could take anything between two minutes and two years to get right. Meanwhile you could do it old-school with artworkers slaving away. Alternatively, you could automate the process to use print stylesheets where you specify the page size and then populate the content with CSS grid layout. The printed catalogue could then be created on demand (and cached) so that it automatically updates itself. This could be a manageable process that you could plan and budget for.

      In your product database you could have fields for layout preferences so that you can specify the featured product for each page and what to downgrade in the presentation. I would say this is definitely viable and one reason this is not done is that any company still invested in print catalogues will have an artworker department and nobody in such a department would invest time into automating their job.

      Some would be hard for them to make at a reasonable price today and they wouldn't sell in big numbers at a higher price.

      Adam Savage recently posted a video about his favorite IKEA cabinet:

      The drawers have box joints which is something I can't imagine IKEA of today doing.

          Every single Ikea kitchen furniture unit I've worked with has been flat pack, made of chipboard and assembled with these bolts that attach to a sort of a worm screw (edit: cam dowel lock nut), and some dowels, maybe a few screws. Not a single sheet of real wood or plywood, no dovetail or finger joints.

      Wait, so you saw this already and didn't share it with the rest of us? How selfish!

    Very cool. I wonder how much of that 1950s IKEA furniture has survived to today.

      Likely more than today’s IKEA furniture will survive until 2100.

    Other than the flower patterns on the sofas, 1976 looks pretty modern actually...

    Where did the Eames chair lookalike disappear to after '68? I want one.

    I never realized that IKEA was over 80 years old.

      They were founded during WWII and they don't like to think about what their founder was doing during those years.

    The thing that has always driven me crazy about these catalogs is that I have an Ikea product that for the life of me I've never been able to find any reference to. So much so that I wouldn't even trust my memory if I didn't have an unopened set from 2002. It's called the GRILLBY, is a design by Gillis Lundgren, and it's a wire mesh wall mount kit for TRYGGVE shelves with hooks screwed into them.

    I thought they looked like the bees knees when I saw them in the store, and the price must have been right because I bought a ton of them. I've been able to cover my walls with shelving ever since, but they must have come from the twilight zone. I've always wondered if the price was right because they were being discontinued and cleared out, but I can't find out when they were continued in the first place.

    I'd be happy to hear if anyone has ever heard of anything like that.

      one must be very pissed to degrade a comment which lines out explicitly wrongly driven design which never took off (it would be existing today!), which looks and feels cold, which gives a feeling of loneliness, handing over some nice "hey-it-looks-good"

      the degrade of design & perception is remarkable.
