Portable Adjustable Memory Foam Pillow

90 × 7 cm (35.4 × 2.7 in) — sized to encircle average adult neck girth (34–42 cm) with 2–3 cm of adjustable overlap. Weight: under 220 g — achieved via calibrated memory cotton density (45 kg/m³) and precision-cut nylon binding. Layering: memory cotton core (primary support), polyester cotton middle layer (soft interface), nylon outer shell (tear-resistant, quick-dry finish). Functional emphasis on passive adaptability: requires no inflation, batteries, or tools — support level changes naturally with user movement and ambient temperature. Warmer conditions soften memory cotton slightly for deeper contouring; cooler environments offer firmer resistance for active posture correction. Used daily by UK-based delivery drivers, freelance designers working from cafés, nursing shift workers during handover breaks, and retirees on coach holidays — universally praised for eliminating ‘neck kink’ upon waking and enabling restorative micro-naps without grogginess or positional discomfort.
