Mattress Firm
Mattress Firm is a national mattress retailer with over 2,300 U.S. store locations and a large digital footprint. Their goal: elevate site performance and UX in time for a major launch.
The Challenge
High page load times, layout shifts, and sluggish interactivity were impacting conversions and increasing bounce rates—especially on mobile. The client needed a lightweight solution to drastically improve Core Web Vitals without slowing down their development schedule.
The Solution
Working closely with Mattress Firm’s in-house design team, Solara6 conducted targeted UX audits, focusing on homepage and mobile flows. We aligned with the client's UI component library to maintain brand cohesion, then implemented edge caching, predictive prefetching, and resource optimization techniques. The result: a faster, more intuitive user experience launched within tight timelines.

UX: Refined navigation and mobile-first layout stability
Collaboration: Seamless integration with in‑house design team using Solara6 audits and implementation
