The biggest reason to consider this mattress is its combination of a pressure-relieving memory foam feel with a patented 7-zone comfort system that targets shoulders, hips, and lower back for steadier support through the night. It ships compressed in a smaller box for a reduced carbon footprint and arrives wrapped in an OEKO-TEX certified cover and CertiPUR-US certified foams for safer, low-chemical sleep.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-Zone Comfort System:\u003c\/strong\u003e Zoned support helps relieve pressure on shoulders, hips, and lower back for more even spinal alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure-Relieving Memory Foam:\u003c\/strong\u003e The top memory foam layer conforms to the body to reduce aches and pains in common pressure areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-Night Freshness:\u003c\/strong\u003e Infusions of green tea and purified charcoal help keep the mattress feeling fresher over time by reducing odors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified Safe Materials:\u003c\/strong\u003e All foams are CertiPUR-US certified and the cover is OEKO-TEX certified, produced without harmful chemicals for safer indoor air.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Shipping:\u003c\/strong\u003e The mattress ships compressed in a smaller box to lower its carbon footprint and is easy to move into a bedroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Year Limited Warranty:\u003c\/strong\u003e A long warranty provides reassurance and covers manufacturing defects for years of normal household use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Ultima is a good fit for side and back sleepers who want a memory foam feel with targeted support and pressure relief, especially if they value certified foams and a fresher-smelling mattress.
