This Novilla 10 inch gel memory foam mattress is a medium firm mattress covered with a soft and breathable fabric. The memory foam mattress suits back/side/stomach sleepers since it can automatically adjust according to the spine curves of the human body and effectively relieve pressure. Besides, the gel foam mattress can lower the motion transfer to guarantee undisturbed sleep, also regulate the temperature to offer you a cool sleep, and relax your body for deep sleep. Coupled with the comfort foam and high-density base foam, the mattress is not too soft or too firm so that the sleepers won't sink into the bed while sleeping, or have back pain. We are committed to creating a comfortable and affordable mattress for our customers. More importantly, our mattresses have been certified by CertiPUR-US, as well as tested by the SGS test, so you can rest assured and enjoy your new mattress! 1.
