The Aurora Luxe is a strong choice if cooling is your priority: the GlacioTex cover integrates phase-change material into its fibers and stays highly effective through the early years, with cooling as its standout performance metric. It is best tuned for moderate-weight sleepers, for whom we project a 5–7 year comfort life, and the 8-inch Ascension coil core rarely fails within 10 years. The top CopperFlex comfort layer softens first, so heavier sleepers should rotate the mattress regularly to protect it.
