Yes. This mattress is completely fiberglass-free. We use CertiPUR-US certified foam and no fiberglass in any layer. You can sleep with peace of mind knowing there are no irritating particles or hidden materials inside. What firmness level is this mattress? It is a medium-firm mattress. It offers enough cushioning to relieve pressure while maintaining solid support for your back—ideal for back, side, and stomach sleepers. A firm version is also available if you prefer a more solid feel. Will I feel my partner's movements at night? No. Independent pocket springs absorb motion at the source, and the foam layer dampens any remaining vibration. If your partner tosses, turns, or gets out of bed, your side stays undisturbed. Does this mattress sleep hot? No. The breathable knit cover pulls heat away from your body, while airflow channels between the foam layers let heat and moisture escape. It is designed to keep you cool and dry throughout the night. How long does it take to expand after unboxing? The mattress arrives compressed and rolled in a box. After unboxing and unrolling, it expands to full shape within 6–8 hours. Any mild new-mattress odor dissipates within a few hours.
