Many adjustable bases come with remote controls for easy adjustments. These bases are often compatible with various mattress types, including memory foam and latex. They can also offer additional features such as built-in massage functions, USB ports for charging devices, and under-bed lighting. Adjustable bases are popular for enhancing sleep quality and overall comfort.
