The ZINUS 12 Inch Ultima is a three-layer memory foam mattress with a medium-firm feel, a tight-top polyester cover and a 500-pound weight limit. Its pressure-relieving memory foam sits over high-density support foam, and the top layer is infused with green tea and charcoal to limit odor and keep the mattress fresher. The foam is CertiPUR-US certified and the cover is OEKO-TEX certified. It suits sleepers who want a dense, conforming foam bed without springs, and it competes with other boxed all-foam mattresses on layer count and certifications rather than on cooling gel or a hybrid coil core.

Owners generally describe the Ultima as a firm, supportive foam bed that holds up well for the money, with many noting it softened slightly after the first weeks. Complaints center on heat retention, a strong new-foam smell at unboxing and slower expansion than expected.
This 12-inch memory foam mattress has three layers and a medium-firm feel. The memory foam conforms to the body to relieve pressure, and a 7-zone comfort system helps ease stress on the joints.
The foam is infused with green tea and purified charcoal to help keep the mattress fresh. The foam is CertiPUR-US certified, and the polyester cover is OEKO-TEX certified.
The mattress ships in a smaller box. Allow 24 to 72 hours for it to expand to its original shape. It comes with a 10-year limited warranty.
