【Comfortable & Breathable Hybrid Mattress In A Box 】 We have designed the SEMIELO 10-inch mattress with a hybrid structure to deliver the perfect night's sleep. This hybrid queen size mattress is made with a breathable bamboo charcoal cover, the highest quality memory foam, supportive & long-lasting high-density foam, and essential Individually-Encased Coils. These ingenious structural designs provide the most comfortable support for sleep. 【Skin-Friendly & Odor-Resistant Bamboo Charcoal Cover】We spend about one-third of our life either sleeping or attempting to do so. It is important to choose a mattress that is skin-friendly, especially for sensitive people. Our premium stretch-knit cover is infused with bamboo charcoal to absorb and dissipate heat to cool the touch surfaces. The bamboo charcoal cover also features odor-resistant and moisture-wicking naturally for a refreshing sleep. 【Pressure Relief & Low Motion Transfer Memory Foam Mattress】This medium-firm mattress is neither too firm nor too soft. Our high-quality memory foam adapts to your body size, shape, and sleeping position to ensure you get a great night's sleep. Specialized foams reduce motion transfer of a partner so your sleep is undisturbed. This queen mattress in a box is ideal for those who need support or suffers from a bad back. You can enjoy the cradle of your bed.
