Yawnder on Encinitas Boulevard stocks over 40 mattress brands for side-by-side comparison in the only showroom of its kind in San Diego County, earning Best Mattress Store honors from San Diego Magazine in both 2024 and 2025. Founded in 2015 as Sleep Sherpa by Ben Trapskin — a research librarian who spent 13 years evaluating information systems before applying that methodology to mattress testing — the company partners with DepthSight Innovations to run proprietary ASTM F1566 firmness and impact-force diagnostics on every floor model, a data-driven approach to sleep wellness that parallels the recovery-focused programming at CorePower Yoga on El Camino Real. Authorized brands on the current showroom floor include Helix, WinkBeds, Nectar, Brooklyn Bedding, Avocado, Birch, and Nest Bedding, all available at or below their direct-to-consumer web pricing. The house-brand Yawnder Luxury Mattress is a 14.5-inch hybrid built with Talalay latex comfort layers, micro-pocketed coils, and a nine-inch nested tempered-coil support system handcrafted in California. Adjustable bases, massage chairs, and Technogel cooling pillows round out the sleep-technology inventory alongside the ergonomic seating and fitness equipment carried by Johnson Fitness & Wellness Store. Free white-glove delivery covers all of San Diego County, and every purchase includes the manufacturer's original 100-night to one-year risk-free trial with full-credit exchange coordination through the Encinitas showroom.
