Look forward to bedtime again with the ISOCOOL 3” Mattress Topper featuring Serene Foam. This mattress topper features 3 inches of plush Serene foam, offering more consistent comfort than traditional memory foam. The quilted cotton cover is overfilled with luxurious polyester fiber and features Outlast Adaptive Comfort material, which helps balance your changing body temperature. Serene foam features Supportive Air Technology, which increases support while reducing pressure. Serene foam is not temperature-sensitive and reduces motion transfer, leading you to a more peaceful night’s sleep.
