This mattress is crafted with advanced breathable fabric that promotes 360° air circulation, effectively dissipating heat and moisture for a consistently dry and comfortable sleeping surface, making it ideal for hot sleepers and those with temperature sensitivities. The mattress cover, infused with chamomile extract, naturally relaxes and encourages deep rest.This mattress features a two-layer design: a top comfort layer of pressure-relieving, soft, rebounding foam; and a bottom support layer of high-density springs reinforced with high-compression technology. This synergistic effect ensures even weight distribution, maintains natural spinal alignment during sleep, and reduces tossing and turning-ideal for combination sleepers, offering customized comfort without sacrificing foundational stability. Our memory foam mattresses carry both CertiPUR-US certification (which measures odor, materials, performance, and durability) and the stringent OEKO-TEX certification. Size: medium.
