【Medium Firm Support for Proper Spinal Alignment】Designed with a Medium Firm feel and offering minimal sink-in, this hybrid mattress provides strong support for your back and spine; ideal for back and stomach sleepers, its Medium Firm build helps reduce back pressure and maintains alignment throughout the night.
