+61%
+12.5%
In this case study, we'll unpack how Lull Mattress achieved a 100% transaction increase and 61% ARPU boost by testing three radically different brand narratives instead of optimizing one mediocre message. More importantly, you'll discover how to escape the positioning trap that kills conversion rates in competitive markets: assuming you know which story resonates before you test it. These strategies will show you how to find your winning narrative through systematic experimentation, not gut feelings or competitor copying.

Lull Mattress operates in one of the most saturated direct-to-consumer categories imaginable, but here's what matters for your strategy: they're a perfect example of a brand that refused to blend into the "sleep better" noise that dominates their space. Like every company in a crowded market, they could have copied successful competitors or stuck with their existing messaging, but instead they chose to test fundamentally different positioning angles to find their unique conversion sweet spot. Sound familiar? Every marketing leader in competitive categories faces this challenge: you know your product works, but you're not sure which story about it will make people actually buy.
The "Everyone Says Sleep Better" Problem
You know that sinking feeling when you realize your entire category sounds identical and your messaging is basically a slightly different version of what everyone else is saying? That's exactly the reality Lull faced in the mattress space. Every brand promises better sleep, uses similar scientific claims, and targets the same tired, stressed consumers with essentially the same value proposition.
Here's what every growth professional in competitive markets learns eventually: when differentiation is hard at the product level, it has to happen at the story level. The mattress industry is littered with failed brands that had great products but couldn't find a message that cut through the noise. We knew from our initial audit that Lull's existing landing page was functionally fine but narratively invisible—it worked, but it didn't stand out in a way that made choosing them feel obvious. At Glued, we've seen this pattern in every saturated category: the winners aren't necessarily the ones with better products, they're the ones who found a better way to talk about their products. Our Free Website Audit & Redesign process revealed that their conversion problem wasn't technical—it was emotional and narrative.

Three Stories, One Experiment
This is where most agencies make a fatal mistake: they pick one positioning angle based on "best practices" or what worked for other brands, then optimize that single approach. At Glued, we believe the only way to discover your winning narrative is to test completely different stories against each other, not minor variations of the same theme.
Every marketing executive faces this positioning dilemma: how do you know which angle will resonate with your market before you spend months optimizing the wrong message? We designed three radically different approaches for Lull: "Sleep Experts" positioned buyers as becoming knowledgeable about sleep science, "Dream Environments" used stunning visuals to showcase different mattress features, and "Effortless Sleep" emphasized simplicity and price value. Each landing page told a fundamentally different story about why someone should choose Lull, targeting different psychological triggers and buyer motivations. At Glued, we've learned that message-market fit is just as important as product-market fit, and the only way to find it is through systematic testing, not assumptions about what should work.

When Testing Reveals Truth
Here's the insight that will change your next positioning strategy: customers will tell you which story they want to hear, but only if you give them genuinely different options to choose from. The results were definitive: 12.5% increase in begin checkout, 100% lift in completed transactions, and 61% improvement in average revenue per user. But here's what makes this strategically valuable—the winning narrative wasn't what anyone predicted.
You know that frustration you feel when your carefully crafted messaging falls flat despite seeming logical and well-researched? This testing approach eliminates that guesswork entirely. The data revealed which psychological triggers actually motivated Lull's audience to convert, which benefits they cared about most, and which way of positioning the brand felt most compelling. At Glued, we've seen this pattern repeatedly: the winning message is rarely the one that sounds best in conference rooms—it's the one that performs best with real customers making real purchasing decisions. The 100% transaction increase proved that finding the right narrative doesn't just improve conversions incrementally; it can fundamentally transform your business economics.

Key Takeaways: Finding Your Voice in the Noise
If you're tired of messaging that tests well internally but fails to move the needle externally, these insights will change how you approach positioning in competitive markets. The opportunity is massive because most brands are still copying each other instead of discovering their unique conversion angle.
1. Test stories, not just elements: Most A/B tests compare button colors or headline variations, but the biggest gains come from testing completely different narratives about why someone should buy. We didn't test "sleep better" versus "sleep great"—we tested whether Lull's audience wanted to become sleep experts, dream about beautiful environments, or embrace effortless solutions. At Glued, we've learned that narrative-level testing reveals insights that element-level optimization never will. If you want to book a call with us, we can show you exactly how this story-testing framework works for your market.
2. Crowded markets reward narrative courage, not safe messaging: You've probably noticed that the brands winning in saturated categories aren't necessarily the ones with better products—they're the ones telling more compelling stories. In the mattress space, everyone talks about comfort and support, but Lull discovered their audience actually responded to a completely different angle. Taking positioning risks is scary, but blending in is scarier for your conversion rates.
3. Buyer psychology varies more than buyer demographics: The same customer might respond to scientific expertise on Tuesday and emotional comfort on Thursday, depending on their mindset and motivation. At Glued, we've learned that testing different psychological approaches often reveals audience segments you didn't know existed, each with different conversion triggers and optimal messaging approaches.
4. Winning narratives compound across all metrics: Notice how Lull didn't just see conversion improvements—they saw increases in begin checkout, completed transactions, and average revenue per user. When you find the right story, it doesn't just convert more visitors; it attracts higher-value customers who are more committed to purchasing because the message resonated more deeply.
5. Message-market fit requires the same rigor as product-market fit: Here's the insight that every marketing leader should take to their next positioning discussion: you can't assume you know which story will work without testing it systematically. At Glued, our approach with Lull proved that positioning isn't a creative decision—it's a strategic one that should be data-driven and customer-validated.
