Design phase
With clear design principles in place, I moved into high-fidelity design to quickly validate ideas with customers that same week.
• Built on the existing Cushy Sofa Bed product page to reduce scope and isolate key changes
• Designed three distinct variations across desktop and mobile to explore different approaches to fabric selection and comparison
• Created a high-fidelity prototype using Koala’s design system and existing components to ensure realism in testing
Validating designs through iterative user feedback
To ensure the designs supported confident decision-making, I validated the designs with participants who closely matched Koala’s target audience.
Across three rounds of unmoderated testing (22 participants total), I focused on:
• How easily users could discover and select the premium fabric option
• Clarity of material details and care information
• Whether the experience justified the higher price point and built purchase confidence
Rather than testing isolated variations, I shared and refined the design iteratively across multiple rounds of feedback. Each round informed targeted improvements, allowing the design to progressively reduce friction, clarify value, and better support higher-consideration purchasing decisions.
22 unmoderated usability tests across three rounds (6–8 users per round)
Objective 1: Improving discoverability of fabric options
The first objective was to validate whether customers could easily discover and understand the available fabric options when browsing the product form.
I focused on whether users could:
• Distinguish between the two available materials
• Understand which colours were available for each fabric
• Identify the price difference between standard and premium options
Objective 1 design iterations
Final iteration for the material selector in the product details form
Outcomes
• Over 70% of users noticed the material selector and supporting text link while browsing
• Users correctly identified that two fabric options were available
• Users understood colour availability per fabric
• Users clearly recognised the price difference when switching between options
Objective 2: Helping customers compare fabric options with confidence
I tested the “What’s the difference?” modal to assess whether it clearly communicated the value of each fabric and supported confident decision-making.
Objective 2 design iterations
Final iteration of the "What's the difference?" modal
Outcomes
• 72% of users opened the modal and could clearly articulate the differences between fabrics
• Users valued the side-by-side comparison table, finding it quick and easy to scan
• Customers understood the tactile differences between standard and premium fabrics
• Sustainability benefits of the premium fabric were clearly recognised
Objective 3: Building confidence through visual detail
I tested the “Take a closer look” modal to understand whether fabric close-ups and supporting information increased confidence in choosing the premium option.
Objective 3 design iterations
Final iteration of the "Take a closer look" modal
Outcomes
• 68% of users opened the modal and viewed close-up fabric imagery
• Users appreciated seeing the texture and weave detail up close
• Fabric information and care instructions were seen as helpful and reassuring
• A mismatch between fabric close-up colour and product imagery was identified, highlighting an opportunity to improve visual consistency
Synthesising insights and aligning on next steps
Following usability testing, I presented the findings to engineering and key stakeholders to align on what we learned, identify risks, and agree on clear recommendations before moving forward.
Insight 1
Price and choice still dominate decisions
64% of users preferred the standard polyester, driven by its lower price, wider colour range, and no perceived comfort trade-off.
Insight 2
The premium value proposition wasn’t clear
Users questioned why the bouclé fabric was positioned as “premium,” citing similar comfort, weaker visual cues, and limited information about feel and quality.
Insight 3
Sustainability benefits lacked clarity
While users noticed the recycled materials, they struggled to understand the broader environmental impact, reducing the perceived value of the premium option.
Insight 4
Limited colour choice reduced consideration
The single premium colour constrained appeal, with users indicating they would be more likely to consider the option if additional colours were available.
