Your new mattress may initially feel firmer than expected. Please allow up to 60 days to acclimate to your new mattress as it naturally adjusts to contour, comfort, and support you best. Premium memory foam is temperature-sensitive; it may feel firmer in cooler temperatures and softer in warmer ones. For your preferred comfort, please allow several hours for your memory foam mattress to adjust to the room’s temperature.
