Sealy Sienna Ortho Plus Mattress in Single, Double, King and Super King Sizes Combining an outstanding level of durability with firm support where it’s needed most, the Sienna Ortho Plus mattress is designed to help you achieve a deep, restful slumber. It’s been exclusively engineered at Sealy for those who prefer sleeping on a firmer mattress. It does this with the unique PostureTech Core Support system, which sees the springs get firmer as they compress. Not only does this provide deep-down comfort, but it also helps to relieve pressure as you sleep. Working in conjunction with this clever system is the PowerPack, which provides additional support to your lumbar region to alleviate those aches that can disturb a good night’s sleep. To top it all off, the Edge Guard is tucked inside the spring unit to provide edge-to-edge comfort and allow you to sleep across the entire surface of the mattress without fear of rolling off. The double-sided design ensures a longer lifespan, as you can flip and turn it every three months to ensure even wear, and it’s finished with a tufted surface for even more support. Please remember to measure your available space before ordering.
