A pregnancy test ad rewrote what a print page could do

A magazine page that responded to its reader

In the December 2017 issue of the Swedish women's magazine Amelia, IKEA Sweden, the Stockholm agency Åkestam Holst and the materials laboratory Mercene Labs ran a print advertisement that doubled as a working pregnancy test.^{1, 2} The page invited the reader to "pee on this", and the chemistry printed below the headline reacted with hCG, the hormone present in a pregnant person's urine, to reveal a discounted "family price" of 495 SEK on the IKEA Sundvik crib, down from the standard 995 SEK.^{2, 3} The advert appeared just before the end of the year and went viral globally in the first week of January 2018, reported as one of the most discussed pieces of print advertising of the decade.

The brief and the partners

The brief from IKEA Sweden was tactical in scope, an annual baby-and-children category communication for the Sundvik crib, but the agency's response moved the format. Åkestam Holst, the long-standing creative agency behind Where Life Happens for IKEA Sweden, proposed an advert in which the price information was visible only to the reader for whom the offer was relevant.^{2, 4} To execute that idea, the agency needed a way to detect a pregnancy on a printed magazine page without producing a separate kit or asking the reader to leave the page.

Mercene Labs, a Stockholm research laboratory specialised in functional surface coatings, took on the chemistry.^{2, 3} The team had four months to translate a clinical lateral-flow pregnancy test into a layout that could survive offset printing, magazine binding and consumer handling.^{2, 3} The starting point was the same antibody chemistry used in pharmacy pregnancy tests: a strip impregnated with antibodies that bound to hCG and produced a colour change.⁵ The challenge was to integrate the strip into a printed page, hide it under the existing artwork, and make it react cleanly enough to reveal the discounted price as a legible numeric value rather than as a generic positive line.

How the page worked

The reader saw a quiet image of the Sundvik crib with the headline "Peeing on this ad may change your life", a short brand line, and the standard 995 SEK price.^{3, 6} The instruction was deliberately direct: place the strip at the bottom of the page in a stream of urine, then wait. If the test detected hCG, a colour-change reaction inside the page revealed a second price strip, the family price of 495 SEK, behind the standard one.^{1, 3} If the test was negative, the page returned to its original layout with no offer revealed. The mechanism rewarded the reader for whom the discounted crib was relevant and asked nothing additional of any other reader.

The science was conventional but the substrate was not. Mercene Labs developed an absorbent paper layer that handled the urine volume, an antibody printing pattern that survived the printing process, and a colour reaction that was legible in domestic lighting. The page was bound into Amelia as a regular full-page advert with a small additional thickness. The four months of development produced a printable strip that worked at consumer scale.

The release and the viral reach

The advert appeared in the December 2017 issue of Amelia, with shelf life through the start of January 2018.¹ The campaign moved to international media on 8 January 2018 when Åkestam Holst and IKEA released a behind-the-scenes film and stills to global trade outlets. The Drum, Adweek, Dezeen, The Guardian and Today.com all covered the story between 9 and 11 January 2018.^{2, 3, 5, 7} The Snopes fact-check confirming the advert's authenticity went live on 11 January, and the Washington Post, Newsweek and the BBC followed in the same week.⁶

The reaction was wide and divided. Trade press treated the work as an exemplary use of medium, a category-redefining moment in print advertising. Mainstream press treated the work as a curiosity that prompted a conversation about pregnancy, advertising and intimacy in domestic media. Across both registers, the advert performed exceptionally on share metrics. Åkestam Holst reported earned-media reach in the hundreds of millions of impressions over the first week of coverage. The advert was nominated at multiple awards, taking two Gold Lions in Print & Publishing and a Bronze Lion in Media at Cannes Lions in 2018 and recognition at the Eurobest and Spikes Asia award programmes.⁸

What it argued for the brand

The advert sat inside the longer Åkestam Holst editorial relationship with IKEA Sweden that began in 2016 with Where Life Happens.^{4, 8} The agency's argument across that platform was that IKEA's most credible advertising was the kind that observed real life closely rather than dramatised it. The pregnancy-test page took that argument to its logical edge. Real life included the moment a pregnancy was confirmed; the brand's response was to turn that moment into the reveal of a relevant offer rather than an unrelated emotional appeal.

For the wider industry, the work became a reference case for measurement-as-mechanic in print, the idea that an advert could carry a measurement instrument inside its substrate and reward the reader's interaction with relevant content. The page is still cited in trade-press long-reads on print innovation, and Mercene Labs continued to work on functional print substrates after the campaign. For IKEA, the campaign confirmed that the brand's editorial confidence in Sweden could extend from television to long-form film to a single magazine page that asked its reader for something the rest of the publication did not.
