The single biggest reason to consider this mattress is the layered gel memory foam construction that targets pressure relief while keeping motion transfer low, making it a sensible pick for couples and back sleepers who wake from pressure points. The mattress ships compressed in a box for easy setup and is fiberglass free with green tea and charcoal gel additions for a fresh-feeling sleep surface.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGel memory foam layer:\u003c\/strong\u003e Conforms to the body to ease pressure at shoulders and hips for more restful sleep.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 in profile:\u003c\/strong\u003e A mid-height build that combines plush top layers with a denser support core for durability and structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium firmness:\u003c\/strong\u003e Offers a balanced feel that supports spinal alignment while still providing noticeable contour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced motion transfer:\u003c\/strong\u003e The high-density support foam base helps isolate movement so partners are less likely to disturb each other.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiberglass free construction:\u003c\/strong\u003e Safer handling and disposal with materials that avoid fiberglass, while added green tea and charcoal aim to help control odor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoxed delivery:\u003c\/strong\u003e Arrives compressed for easy setup; simply unroll and allow up to 48 hours to fully expand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis mattress is a solid option for couples and back sleepers who appreciate \u003cstrong\u003epressure relief\u003c\/strong\u003e and want reduced motion disturbance.
