Ever wonder how some D2C brands scale their product catalogues without drowning in complexity?
Most don't. They either freeze after launching a hero product (terrified that expansion will dilute focus) or sprint into chaos (launching everything, optimising nothing). The first approach caps revenue. The second burns cash.
SleepyHug took a different path, and the results speak volumes. In just 13 months, they scaled from a tight starting catalogue of 39 SKUs to a comprehensive sleep ecosystem with 500+ products.
This piece breaks down exactly how they did it. You'll see the selection framework that determined which products to launch (and when), the operational backbone that made over 500 SKUs manageable, and the analytics infrastructure that maintained economic integrity.
Whether you're running a mattress brand, a beauty line, or a home goods company, the principles are universal. Because a smart product line extension strategy is about capturing more of your customer's problem space while strengthening your core business.
Let’s find the product line extension strategy that scaled SleepyHug beyond ₹100Cr in under 13 months.
Let's start with a reality check: if your brand lives or dies by one hero SKU, you're renting shelf space until a competitor outspends you or a platform changes its algorithm.
But here's the trap. Add too many SKUs too fast, and you're suddenly managing 200 products with 20% dead stock, confused messaging, and logistics that bleed cash. So what's the middle path?
For D2C brands, especially in categories like sleep, home, or wellness, a product line extension strategy is about capturing wallet share across the customer's entire problem space.
However, most brands stumble during this as they confuse "more products" with "better strategy." They launch without validating demand, without building ops to fulfil, without checking if margins hold at scale.
Before adding a single SKU, SleepyHug spent months in research mode. Not market reports or competitor analysis - actual hands-on testing.
The team physically evaluated 300+ mattresses from competitors, testing everything from foam density to edge support. They mined thousands of customer reviews, looking for patterns in complaints and praise.
As a result, they had a ranked list of attributes that actually mattered to Indian consumers: cooling technology, spinal alignment, motion isolation, and honest pricing.
This wasn't an academic exercise. The mattress market in India is expected to reach a projected revenue of USD 4.5 billion by 2030[1]. Understanding which specific foam configurations and features drove satisfaction became the foundation for every extension decision. This was all about proving product-market fit in this industry.
SleepyHug launched with just 39 SKUs - a deliberately constrained catalogue that covered three core categories:
Each category had essential size variations (single to California King) but nothing more. No confusion. No paradox of choice.
This tight focus allowed SleepyHug to perfect their foundational products before extending. They could monitor quality, gather feedback, and understand purchase patterns without the operational complexity of managing hundreds of variants.
The focus was initially on nailing their supply chain process for scale.
Here's where SleepyHug's strategy diverged from typical D2C playbooks. Instead of launching whatever seemed trendy, they extended in deliberate concentric circles:
First, they filled gaps in their core mattress lines. If the queen-size medium-firm was selling well, they'd add king and twin sizes. If customers requested softer options, they'd introduce plush variants within the same model family.
This horizontal extension maintained consistent pricing and quality while addressing specific customer needs.
Next came functional innovations within existing categories. The AirCell Honeycomb Grid technology got integrated across lines. Orthopaedic variants with enhanced lumbar support joined the catalogue. Cooling gel layers addressed India's climate challenges.
Each addition solved a specific problem identified through customer feedback. Returns citing "too hot" led to cooling variants. Complaints about back pain triggered orthopaedic extensions.
Only after establishing mattress dominance did SleepyHug extend into accessories. But even here, the logic was tight: products that enhanced the core mattress experience.
SleepyHug recognised that accessories weren't just add-ons, but they were retention tools that kept customers within the brand ecosystem.
With 500+ SKUs, complexity in pricing strategy could have destroyed margins. SleepyHug prevented this through Intellsys.ai's pricing engine, which tracked:
Each SKU had defined pricing corridors. If competitive pressure pushed prices below minimum margins, the product was either repositioned or discontinued.
The discipline showed: despite massive SKU proliferation, SleepyHug maintained healthy unit economics throughout their scaling journey.
Most brands struggle operationally when SKU counts explode. SleepyHug built infrastructure ahead of complexity:
Working with a 40+ year experienced manufacturer provided process maturity from day one. Quality control, batch consistency, and production flexibility were built-in, not bolted-on.
The partnership enabled rapid prototyping and small-batch production, which are critical for the test-and-learn extension approach.
SleepyHug implemented Deal Run Rate (DRR) forecasting, calculating daily sales velocity separately for:
This prevented the twin disasters of stockouts (lost sales) and overstock (dead capital).
Nine fulfilment centres across five cities meant regional inventory & supply chain optimisation. Fast-moving SKUs were stocked deeper in high-demand regions. Slow movers were consolidated in central warehouses.
Every extension passed through a strict stage-gate innovation model:
Crucially, when early feedback identified issues (like initial cover stitching problems), SleepyHug fixed them across the entire affected range. This commitment to quality protected brand equity and led to sustainable brand growth even as variety expanded.
SleepyHug's journey from 39 to 500+ SKUs wasn't about having more products. It was about serving customers more completely. Each extension deepened relationships, increased value, and built competitive moats.
The SleepyHug playbook isn't complicated: Research deeply. Test cheaply. Scale quickly. Kill ruthlessly. Maintain quality religiously.
But execution? That's where discipline separates the category leaders from the inventory managers.

Q1. What is a Product Line Extension Strategy?
A product line extension is a marketing strategy that uses an existing brand to introduce a new item into the same product line. It helps attract new customers, increase market share, and offer variety without creating a new brand.
Q2. What is a product line and its example?
A product line is a group of related products under a single brand that share similar functions or target the same customer needs. For example, SleepyHug’s product line includes different types of mattresses, pillows, and sleep accessories designed to improve sleep quality.
Q2. What is an example of a product line extension strategy?
An example is SleepyHug, which expanded its product line from basic mattresses to include orthopedic variants, cooling gel options, pillows, and mattress protectors; catering to diverse sleep needs while staying within the same category.
